Uses for Amnesteem Capsules

Severe Recalcitrant Nodular Acne

Amnesteem is indicated for the treatment of severe recalcitrant nodular acne. Nodules are inflammatory lesions with a diameter of 5 mm or greater. The nodules maybecome suppurative or hemorrhagic. “Severe,” by definition, means “many” as opposed to “few or several” nodules. Because of significant adverse effects associatedwith its use, Amnesteem should be reserved for patients with severe nodular acne who are unresponsive to conventional therapy, including systemic antibiotics. Inaddition, Amnesteem is indicated only for those patients who are not pregnant, because Amnesteem can cause life threatening birth defects (see BOX WARNING).

A single course of therapy for 15 to 20 weeks has been shown to result in complete and prolonged remission of disease in many patients.^1,3,4 If a second course oftherapy is needed, it should not be initiated until at least 8 weeks after completion of the first course, because experience has shown that patients may continue toimprove while off Amnesteem. The optimal interval before retreatment has not been defined for patients who have not completed skeletal growth (see WARNINGS:Skeletal: Bone Mineral Density, Hyperostosis, Premature Epiphyseal Closure).

Dosage for Amnesteem Capsules

Amnesteem should be administered with a meal (see PATIENT INFORMATION).

The recommended dosage range for Amnesteem is 0.5 to 1 mg/kg/day given in two divided doses with food for 15 to 20 weeks. In studies comparing 0.1, 0.5, and 1mg/kg/day,⁸ it was found that all dosages provided initial clearing of disease, but there was a greater need for retreatment with the lower dosages. During treatment, thedose may be adjusted according to response of the disease and/or the appearance of clinical side effects — some of which may be dose related. Adult patients whosedisease is very severe with scarring or is primarily manifested on the trunk may require dose adjustments up to 2 mg/kg/day, as tolerated. Failure to take Amnesteemwith food will significantly decrease absorption. Before upward dose adjustments are made, the patients should be questioned about their compliance with foodinstructions.

The safety of once daily dosing with Amnesteem has not been established. Once daily dosing is not recommended.

If the total nodule count has been reduced by more than 70% prior to completing 15 to 20 weeks of treatment, the drug may be discontinued. After a period of 2 monthsor more off therapy, and if warranted by persistent or recurring severe nodular acne, a second course of therapy may be initiated. The optimal interval before retreatmenthas not been defined for patients who have not completed skeletal growth. Long-term use of Amnesteem, even in low doses, has not been studied, and is notrecommended. It is important that Amnesteem be given at the recommended doses for no longer than the recommended duration. The effect of long-term use ofAmnesteem on bone loss is unknown (see WARNINGS: Skeletal: Bone Mineral Density, Hyperostosis, And Premature Epiphyseal Closure).

Contraceptive measures must be followed for any subsequent course of therapy (see PRECAUTIONS).

Side Effects for Amnesteem Capsules

Clinical Trials And Post-Marketing Surveillance

The adverse reactions listed below reflect the experience from investigational studies of Amnesteem, and the post-marketing experience. The relationship of some ofthese events to Amnesteem therapy is unknown. Many of the side effects and adverse reactions seen in patients receiving Amnesteem are similar to those described inpatients taking very high doses of vitamin A (dryness of the skin and mucous membranes, e.g., of the lips, nasal passage, and eyes).

Drug Interactions for Amnesteem Capsules

Vitamin A

Because of the relationship of Amnesteem to vitamin A, patients should be advised against taking vitamin supplements containing vitamin A to avoidadditive toxic effects.

Tetracyclines

Concomitant treatment with Amnesteem and tetracyclines should be avoided because Amnesteem use has been associated with a number of casesof pseudotumor cerebri (benign intracranial hypertension), some of which involved concomitant use of tetracyclines.

Micro-Dosed Progesterone Preparations

Micro-dosed progesterone preparations (“minipills” that do not contain an estrogen) may be an inadequate method ofcontraception during Amnesteem therapy. Although other hormonal contraceptives are highly effective, there have been reports of pregnancy from patients whocan become pregnant who have used combined oral contraceptives, as well as transdermal patch/injectable/implantable/vaginal ring hormonal birth controlproducts. These reports are more frequent for patients who can become pregnant who use only a single form of contraception. It is not known if hormonalcontraceptives differ in their effectiveness when used with Amnesteem. Therefore, it is critically important for patients who can become pregnant to select andcommit to use two forms of effective contraception simultaneously, at least one of which must be a primary form (see PRECAUTIONS ).

Norethindrone/Ethinyl Estradiol

In a study of 31 premenopausal female patients with severe recalcitrant nodular acne receiving Ortho-Novum^® 7/7/7 Tablets asan oral contraceptive agent, Amnesteem at the recommended dose of 1 mg/kg/day, did not induce clinically relevant changes in the pharmacokinetics of ethinylestradiol and norethindrone and in the serum levels of progesterone, follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Prescribers are advised toconsult the package insert of medication administered concomitantly with hormonal contraceptives, since some medications may decrease the effectiveness ofthese birth control products.

St. John’s Wort

Amnesteem use is associated with depression in some patients (see WARNINGS: Psychiatric Disorders and ADVERSE REACTIONS:Psychiatric). Patients should be prospectively cautioned not to self-medicate with the herbal supplement St. John’s Wort because a possible interaction has beensuggested with hormonal contraceptives based on reports of breakthrough bleeding on oral contraceptives shortly after starting St. John's Wort. Pregnancies havebeen reported by users of combined hormonal contraceptives who also used some form of St. John's Wort.

Phenytoin

Amnesteem has not been shown to alter the pharmacokinetics of phenytoin in a study in seven healthy volunteers. These results are consistent with the in vitro finding that neither isotretinoin nor its metabolites induce or inhibit the activity of the CYP 2C9 human hepatic P450 enzyme. Phenytoin is known to cause osteomalacia. No formal clinical studies have been conducted to assess if there is an interactive effect on bone loss between phenytoin and Amnesteem.Therefore, caution should be exercised when using these drugs together.

Systemic Corticosteroids

Systemic corticosteroids are known to cause osteoporosis. No formal clinical studies have been conducted to assess if there is aninteractive effect on bone loss between systemic corticosteroids and Amnesteem. Therefore, caution should be exercised when using these drugs together.

Warnings for Amnesteem Capsules

Psychiatric Disorders

Amnesteem may cause depression, psychosis and, rarely, suicidal ideation, suicide attempts, suicide, and aggressive and/or violent behaviors. No mechanism ofaction has been established for these events (see ADVERSE REACTIONS: Psychiatric). Prescribers should read the brochure, Recognizing PsychiatricDisorders in Adolescents and Young Adults: A Guide for Prescribers of Isotretinoin.Prescribers should be alert to the warning signs of psychiatric disorders toguide patients to receive the help they need. Therefore, prior to initiation of Amnesteem therapy, patients and family members should be asked about anyhistory of psychiatric disorder, and at each visit during therapy patients should be assessed for symptoms of depression, mood disturbance, psychosis, oraggression to determine if further evaluation may be necessary. Signs and symptoms of depression, as described in the brochure (“Recognizing PsychiatricDisorders in Adolescents and Young Adults”), include sad mood, hopelessness, feelings of guilt, worthlessness or helplessness, loss of pleasure or interest inactivities, fatigue, difficulty concentrating, change in sleep pattern, change in weight or appetite, suicidal thoughts or attempts, restlessness, irritability, actingon dangerous impulses, and persistent physical symptoms unresponsive to treatment. Patients should stop Amnesteem and the patient or a family membershould promptly contact their prescriber if the patient develops depression, mood disturbance, psychosis, or aggression, without waiting until the next visit.Discontinuation of Amnesteem therapy may be insufficient; further evaluation may be necessary. While such monitoring may be helpful, it may not detect allpatients at risk. Patients may report mental health problems or family history of psychiatric disorders. These reports should be discussed with the patientand/or the patient’s family. A referral to a mental health professional may be necessary. The physician should consider whether Amnesteem therapy isappropriate in this setting; for some patients the risks may outweigh the benefits of Amnesteem therapy.

Pseudotumor Cerebri

Amnesteem use has been associated with a number of cases of pseudotumor cerebri (benign intracranial hypertension), some of which involved concomitantuse of tetracyclines. Concomitant treatment with tetracyclines should therefore be avoided. Early signs and symptoms of pseudotumor cerebri includepapilledema, headache, nausea and vomiting, and visual disturbances. Patients with these symptoms should be screened for papilledema and, if present, theyshould be told to discontinue Amnesteem immediately and be referred to a neurologist for further diagnosis and care (see ADVERSE REACTIONS:Neurological).

Serious Skin Reactions

There have been post-marketing reports of erythema multiforme and severe skin reactions [e.g., Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN)]associated with isotretinoin use. These events may be serious and result in death, life-threatening events, hospitalization, or disability. Patients should be monitoredclosely for severe skin reactions, and discontinuation of Amnesteem should be considered if warranted.

Pancreatitis

Acute pancreatitis has been reported in patients with either elevated or normal serum triglyceride levels. In rare instances, fatal hemorrhagic pancreatitis has beenreported. Amnesteem should be stopped if hypertriglyceridemia cannot be controlled at an acceptable level or if symptoms of pancreatitis occur.

Lipids

Elevations of serum triglycerides in excess of 800 mg/dL have been reported in patients treated with Amnesteem. Marked elevations of serum triglycerides werereported in approximately 25% of patients receiving Amnesteem in clinical trials. In addition, approximately 15% developed a decrease in high-density lipoproteins andabout 7% showed an increase in cholesterol levels. In clinical trials, the effects on triglycerides, HDL, and cholesterol were reversible upon cessation of Amnesteemtherapy. Some patients have been able to reverse triglyceride elevation by reduction in weight, restriction of dietary fat and alcohol, and reduction in dose whilecontinuing Amnesteem.⁵

Blood lipid determinations should be performed before Amnesteem is given and then at intervals until the lipid response to Amnesteem is established, which usuallyoccurs within 4 weeks. Especially careful consideration must be given to risk/benefit for patients who may be at high risk during Amnesteem therapy (patients withdiabetes, obesity, increased alcohol intake, lipid metabolism disorder or familial history of lipid metabolism disorder). If Amnesteem therapy is instituted, more frequentchecks of serum values for lipids and/or blood sugar are recommended (see PRECAUTIONS: Laboratory Tests).

The cardiovascular consequences of hypertriglyceridemia associated with Amnesteem are unknown.

Animal Studies

In rats given 8 or 32 mg/kg/day of isotretinoin (1.3 to 5.3 times the recommended clinical dose of 1 mg/kg/day after normalization for total body surface area) for 18months or longer, the incidences of focal calcification, fibrosis and inflammation of the myocardium, calcification of coronary, pulmonary and mesenteric arteries, andmetastatic calcification of the gastric mucosa were greater than in control rats of similar age. Focal endocardial and myocardial calcifications associated with calcification of the coronary arteries were observed in two dogs after approximately 6 to 7 months of treatment with isotretinoin at a dosage of 60 to 120 mg/kg/day (30to 60 times the recommended clinical dose of 1 mg/kg/day, respectively, after normalization for total body surface area).

Hearing Impairment

Impaired hearing has been reported in patients taking Amnesteem; in some cases, the hearing impairment has been reported to persist after therapy has beendiscontinued. Mechanism(s) and causality for this event have not been established. Patients who experience tinnitus or hearing impairment should discontinueAmnesteem treatment and be referred for specialized care for further evaluation (see ADVERSE REACTIONS: Special Senses).

Hepatotoxicity

Clinical hepatitis considered to be possibly or probably related to Amnesteem therapy has been reported. Additionally, mild to moderate elevations of liver enzymeshave been observed in approximately 15% of individuals treated during clinical trials, some of which normalized with dosage reduction or continued administration ofthe drug. If normalization does not readily occur or if hepatitis is suspected during treatment with Amnesteem, the drug should be discontinued and the etiology furtherinvestigated.

Inflammatory Bowel Disease

Amnesteem has been associated with inflammatory bowel disease (including regional ileitis) in patients without a prior history of intestinal disorders. In some instances,symptoms have been reported to persist after Amnesteem treatment has been stopped. Patients experiencing abdominal pain, rectal bleeding or severe diarrhea shoulddiscontinue Amnesteem immediately (see ADVERSE REACTIONS: Gastrointestinal).

Skeletal

Bone Mineral Density

Effects of multiple courses of Amnesteem on the developing musculoskeletal system are unknown. There is some evidence that long-term, high-dose, or multiplecourses of therapy with isotretinoin have more of an effect than a single course of therapy on the musculoskeletal system. In an open-label clinical trial (N = 217) of asingle course of therapy with Amnesteem for severe recalcitrant nodular acne, bone density measurements at several skeletal sites were not significantly decreased(lumbar spine change > -4% and total hip change > -5%) or were increased in the majority of patients. One patient had a decrease in lumbar spine bone mineral density> 4% based on unadjusted data. Sixteen (7.9%) patients had decreases in lumbar spine bone mineral density > 4%, and all the other patients (92%) did not havesignificant decreases or had increases (adjusted for body mass index). Nine patients (4.5%) had a decrease in total hip bone mineral density > 5% based on unadjusteddata. Twenty-one (10.6%) patients had decreases in total hip bone mineral density > 5%, and all the other patients (89%) did not have significant decreases or hadincreases (adjusted for body mass index). Follow-up studies performed in eight of the patients with decreased bone mineral density for up to 11 months thereafterdemonstrated increasing bone density in five patients at the lumbar spine, while the other three patients had lumbar spine bone density measurements below baselinevalues. Total hip bone mineral densities remained below baseline (range –1.6% to –7.6%) in five of eight patients (62.5%).

In a separate open-label extension study of ten patients, ages 13 to 18 years, who started a second course of Amnesteem 4 months after the first course, two patientsshowed a decrease in mean lumbar spine bone mineral density up to 3.25% (see PRECAUTIONS: Pediatric Use).

Spontaneous reports of osteoporosis, osteopenia, bone fractures, and delayed healing of bone fractures have been seen in the Amnesteem population. While causality toAmnesteem has not been established, an effect cannot be ruled out. Longer term effects have not been studied. It is important that Amnesteem be given at therecommended doses for no longer than the recommended duration.

Hyperostosis

A high prevalence of skeletal hyperostosis was noted in clinical trials for disorders of keratinization with a mean dose of 2.24 mg/kg/day. Additionally, skeletalhyperostosis was noted in six of eight patients in a prospective study of disorders of keratinization.⁶ Minimal skeletal hyperostosis and calcification of ligaments andtendons have also been observed by x-ray in prospective studies of nodular acne patients treated with a single course of therapy at recommended doses. The skeletaleffects of multiple Amnesteem treatment courses for acne are unknown.

In a clinical study of 217 pediatric patients (12 to 17 years) with severe recalcitrant nodular acne, hyperostosis was not observed after 16 to 20 weeks of treatment withapproximately 1 mg/kg/day of Amnesteem given in two divided doses. Hyperostosis may require a longer time frame to appear. The clinical course and significanceremain unknown.

Premature Epiphyseal Closure

There are spontaneous reports of premature epiphyseal closure in acne patients receiving recommended doses of Amnesteem. The effect of multiple courses ofAmnesteem on epiphyseal closure is unknown.

Vision Impairment

Visual problems should be carefully monitored. All Amnesteem patients experiencing visual difficulties should discontinue Amnesteem treatment and have anophthalmological examination (see ADVERSE REACTIONS: Special Senses).

Corneal Opacities

Corneal opacities have occurred in patients receiving Amnesteem for acne and more frequently when higher drug dosages were used in patients with disorders ofkeratinization. The corneal opacities that have been observed in clinical trial patients treated with Amnesteem have either completely resolved or were resolving atfollow-up 6 to 7 weeks after discontinuation of the drug (see ADVERSE REACTIONS: Special Senses).

Decreased Night Vision

Decreased night vision has been reported during Amnesteem therapy and in some instances the event has persisted after therapy was discontinued. Because the onset insome patients was sudden, patients should be advised of this potential problem and warned to be cautious when driving or operating any vehicle at night.

Precautions for Amnesteem Capsules

Amnesteem must only be prescribed by prescribers who are enrolled and activated with the iPLEDGE REMS. Amnesteem must only be dispensed by a pharmacyenrolled and activated with iPLEDGE, and must only be dispensed to patients who are enrolled and meet all the requirements of iPLEDGE. Enrolled and activatedpharmacies must receive Amnesteem only from wholesalers enrolled with iPLEDGE.

iPLEDGE REMS requirements for wholesalers, prescribers, and pharmacists are described below:

Wholesalers

For the purpose of the iPLEDGE REMS, the term wholesaler refers to wholesaler, distributor, and/or chain pharmacy distributor. To distribute Amnesteem, wholesalers must be enrolled with iPLEDGE, and agree to meet all iPLEDGE requirements for wholesale distribution of isotretinoin products. Wholesalers must enroll with iPLEDGE by signing and returning the iPLEDGE wholesaler agreement that affirms they will comply with all iPLEDGE requirements for distribution of isotretinoin.These include:

• Enrolling prior to distributing isotretinoin and re-enrolling annually thereafter
• Distributing only FDA approved isotretinoin product
• Only shipping isotretinoin to
  • wholesalers enrolled in the iPLEDGE REMS with prior written consent from the manufacturer or
  • pharmacies licensed in the US and enrolled and activated in the iPLEDGE REMS
• Notifying the isotretinoin manufacturer (or delegate) of any non-enrolled and/or non-activated pharmacy or unenrolled wholesaler that attempts to orderisotretinoin
• Complying with inspection/audit of wholesaler records for verification of compliance with the iPLEDGE REMS by the isotretinoin manufacturer (or delegate)
• Returning to the manufacturer (or delegate) any undistributed product if the wholesaler is deactivated by the iPLEDGE REMS or if the wholesaler chooses to notre-enroll annually

Prescribers

To prescribe isotretinoin, the prescriber must be enrolled and activated with the pregnancy risk management program iPLEDGE. Prescribers can enroll by signing andreturning the completed enrollment form. Prescribers can only activate their enrollment by affirming that they meet requirements and will comply with all iPLEDGErequirements by attesting to the following points:

• I know the risk and severity of fetal injury/birth defects from isotretinoin.
• I know the risk factors for unplanned pregnancy and the effective measures for avoidance of unplanned pregnancy.
• I have the expertise to provide the patient with detailed pregnancy prevention counseling, or I will refer the patient to an expert for such counseling, reimbursedby the manufacturer.
• I will comply with the iPLEDGE REMS requirements described in the booklet entitled iPLEDGE REMS Prescriber Guide.
• Before beginning treatment of patients who can become pregnant with isotretinoin, and on a monthly basis, the patient will be counseled to avoid pregnancy byusing two forms of contraception simultaneously and continuously for at least one month prior to initiation of isotretinoin treatment, during isotretinoin treatmentand for one month after discontinuing isotretinoin treatment, unless the patient commits to continuous abstinence, not having any sexual contact with a partnerthat could result in pregnancy.
• I will not prescribe isotretinoin to any patient who can become pregnant until verifying the patient has a negative screening pregnancy test and monthly negativeCLIA-certified (Clinical Laboratory Improvement Amendment) pregnancy tests. Patients should have a pregnancy test at the completion of the entire course ofisotretinoin and another pregnancy test one month later.
• I will report any pregnancy case that I become aware of while the patient who can become pregnant is on isotretinoin or one month after the last dose to thepregnancy registry.

To prescribe isotretinoin, the prescriber must access the iPLEDGE system via the internet (www.ipledgeprogram.com) or telephone (1-866-495-0654) to:

1. Register each patient in the iPLEDGE REMS.
2. Confirm monthly that each patient has received counseling and education.
3. For patients who can become pregnant:
   • Enter patient’s two chosen forms of contraception each month.
   • Enter monthly result from CLIA-certified laboratory conducted pregnancy test.

Isotretinoin must only be prescribed to patients who are known not to be pregnant as confirmed by a negative CLIA-certified laboratory conducted pregnancy test.

Isotretinoin must only be dispensed by a pharmacy enrolled and activated with the pregnancy risk management program iPLEDGE and only when the enrolled patientmeets all the requirements of the iPLEDGE REMS. Meeting the requirements for a patient who can become pregnant signifies that the patient:

• Has been counseled and has signed a Patient Enrollment Form for Patients who can get Pregnant that contains warnings about the risk of potential birth defects ifthe fetus is exposed to isotretinoin. The patient must sign the informed consent form before starting treatment and patient counseling must also be done at thattime and on a monthly basis thereafter.
• Has had two negative urine or serum pregnancy tests with a sensitivity of at least 25 mIU/mL before receiving the initial isotretinoin prescription. The first test (ascreening test) is obtained by the prescriber when the decision is made to pursue qualification of the patient for isotretinoin. The second pregnancy test (aconfirmation test) must be done in a CLIA-certified laboratory. The interval between the two tests should be at least 19 days.
  • For patients with regular menstrual cycles, the second pregnancy test should be done during the first 5 days of the menstrual period immediately precedingthe beginning of isotretinoin therapy and after the patient has used two forms of contraception for one month.
  • For patients with amenorrhea, irregular cycles, or using a contraceptive form that precludes withdrawal bleeding, the second pregnancy test must be doneimmediately preceding the beginning of isotretinoin therapy and after the patient has used two forms of contraception for one month.
• Has had a negative result from a urine or serum pregnancy test in a CLIA-certified laboratory before receiving each subsequent course of isotretinoin. Apregnancy test must be repeated every month, in a CLIA-certified laboratory, prior to the patient who can become pregnant receiving each prescription.
• Has selected and has committed to use two forms of effective contraception simultaneously, at least one of which must be a primary form, unless the patientcommits to continuous abstinence not having any sexual contact with a partner that could result in pregnancy, or the patient has undergone a hysterectomy orbilateral oophorectomy, or has been medically confirmed to be post-menopausal. Patients must use two forms of effective contraception for at least one monthprior to initiation of isotretinoin therapy, during isotretinoin therapy, and for one month after discontinuing isotretinoin therapy. Counseling about contraceptionand behaviors associated with an increased risk of pregnancy must be repeated on a monthly basis.

If the patient has unprotected sexual contact with a partner that could result in pregnancy at any time one month before, during, or one month after therapy, the patientmust:

1. Stop taking Amnesteem immediately, if on therapy
2. Have a pregnancy test at least 19 days after the last act of unprotected sexual contact with a partner that could result in pregnancy
3. Start using two forms of effective contraception simultaneously again for one month before resuming Amnesteem therapy
4. Have a second pregnancy test after using two forms of effective contraception for one month as described above depending on whether the patient has regularmenses or not.

Effective forms of contraception include both primary and secondary forms of contraception:

Primary forms	Secondary forms
	Barrier:
tubal sterilization male vasectomy intrauterine device hormonal (combination oral contraceptives, transdermal patch, injectables, implantables, orvaginal ring)	male latex condom with or without spermicide diaphragm with spermicide cervical cap with spermicide
	Other:
	vaginal sponge (contains spermicide)

Any birth control method can fail. There have been reports of pregnancy from patients who can become pregnant who have used oral contraceptives, as well astransdermal patch/injectable/implantable/vaginal ring hormonal birth control products; these pregnancies occurred while these patients were taking Amnesteem. Thesereports are more frequent for patients who use only a single form of contraception. Therefore, it is critically important that patients who can become pregnant use twoeffective forms of contraception simultaneously. Patients must receive warnings about the importance of choosing one primary method and a secondary method ofcontraception and that the patient must be compliant in use as outlined in the Guide for Patients who can get Pregnant.

Using two forms of contraception simultaneously substantially reduces the chances that a patient will become pregnant over the risk of pregnancy with either formalone. A drug interaction that decreases effectiveness of hormonal contraceptives has not been entirely ruled out for Amnesteem (see DRUG INTERACTIONS). Although hormonal contraceptives are highly effective, prescribers are advised to consult the package insert of any medication administeredconcomitantly with hormonal contraceptives, since some medications may decrease the effectiveness of these birth control products.

Patients should be prospectively cautioned not to self-medicate with the herbal supplement St. John’s Wort because a possible interaction has been suggested withhormonal contraceptives based on reports of breakthrough bleeding on oral contraceptives shortly after starting St. John’s Wort. Pregnancies have been reported byusers of combined hormonal contraceptives who also used some form of St. John’s Wort.

If a pregnancy does occur during Amnesteem treatment, Amnesteem must be discontinued immediately. The patient should be referred to an Obstetrician-Gynecologistexperienced in reproductive toxicity for further evaluation and counseling. Any suspected fetal exposure during or one month after Amnesteem therapy must bereported immediately to the FDA via the MedWatch number 1-800-FDA-1088 and also to the iPLEDGE Pregnancy Registry at 1-866-495-0654 or via the internet(www.ipledgeprogram.com).

Pharmacists

To dispense isotretinoin, pharmacies must be enrolled and activated with the pregnancy risk management program iPLEDGE.

The Responsible Site Pharmacist must enroll the pharmacy by signing and returning the completed Pharmacy Enrollment Form. After enrolling, the Responsible SitePharmacist can only activate the pharmacy enrollment by affirming that they meet requirements and will comply with all iPLEDGE requirements by attesting to thefollowing points:

• I know the risk and severity of fetal injury/birth defects from isotretinoin.
• I will train all pharmacists who participate in the filling and dispensing of isotretinoin prescriptions, on the iPLEDGE REMS requirements.
• I will comply and seek to ensure all pharmacists who participate in the filling and dispensing of isotretinoin prescriptions comply with the iPLEDGE REMSrequirements described in the booklet entitled Pharmacist Guide, specifically the “Key Information for Pharmacists” section including the following dispensing information:
  • Prescriptions must be obtained no later than the “Do Not Dispense To After” date, and if not obtained, then the RMA must be reversed in the iPLEDGEREMS system and the product returned to inventory.
• I understand and will comply with the Non-Compliance Action Policy.
• I will obtain Amnesteem product only from iPLEDGE enrolled wholesalers.
• I will not sell, buy, borrow, loan or otherwise transfer isotretinoin in any manner to or from another pharmacy.
• I will return to the manufacturer (or delegate) any unused product if the pharmacy is deactivated by the iPLEDGE REMS or if the pharmacy chooses to notreactivate annually.
• I will not fill isotretinoin for any party other than a qualified patient.
• I will comply with the audits by the iPLEDGE Sponsors or third party acting on behalf of the iPLEDGE Sponsors to ensure that all processes and procedures arein place and being followed for the iPLEDGE REMS.

To dispense isotretinoin, the pharmacist must:

1. be trained by the Responsible Site Pharmacist concerning the iPLEDGE REMS requirements.
2. obtain authorization from the iPLEDGE REMS via the internet (www.ipledgeprogram.com), or telephone (1-866-495-0654) for every isotretinoin prescription.Authorization signifies that the patient has met all program requirements and is qualified to receive Amnesteem.
3. write the Risk Management Authorization (RMA) number on the prescription.

Amnesteem must only be dispensed:

• in no more than a 30-day supply
• with an Amnesteem Medication Guide
• after authorization from the iPLEDGE REMS
• prior to the “do not dispense to patient after” date provided by the iPLEDGE system (within 30 days of the office visit for patients who cannot become pregnantand within 7 days of the date of specimen collection for patients who can become pregnant)
• with a new prescription for refills and another authorization from the iPLEDGE REMS (No automatic refills are allowed)

An Amnesteem Medication Guide must be given to the patient each time Amnesteem is dispensed, as required by law. This Amnesteem Medication Guide is animportant part of the risk management program for the patients.

Amnesteem must not be prescribed, dispensed or otherwise obtained through the internet or any other means outside of the iPLEDGE REMS. Only FDA-approvedAmnesteem products must be distributed, prescribed, dispensed, and used. Patients must obtain Amnesteem prescriptions only at U.S. licensed pharmacies.

A description of the iPLEDGE REMS educational materials available with iPLEDGE is provided below. The main goal of these educational materials is to explain theiPLEDGE REMS requirements and to reinforce the educational messages.

1. The Prescriber Guide includes: isotretinoin teratogenic potential, information on pregnancy testing, and the method to complete a qualified Amnesteemprescription.
2. Pharmacist Guide includes: isotretinoin teratogenic potential and the method to obtain authorization to dispense an isotretinoin prescription.
3. The iPLEDGE REMS is a systematic approach to comprehensive patient education about their responsibilities and includes education for contraceptioncompliance and reinforcement of educational messages. The iPLEDGE REMS includes information on the risks and benefits of Amnesteem which is linked to theMedication Guide dispensed by pharmacists with each isotretinoin prescription.
4. The Fact Sheet for the iPLEDGE REMS includes information on the iPLEDGE REMS, the product indications and safety information. This handout is providedto both the patient who can become pregnant and the patient who cannot become pregnant. The Patient Enrollment Form for Patients who cannot get Pregnant isprovided to all patients.
5. Patients who can become pregnant are provided with a Guide for Patients Who Can Get Pregnant , which contains information on isotretinoin therapy includingprecautions and warnings, and a second Patient Enrollment Form for Patients who can get Pregnant concerning birth defects, and a toll-free line which providesAmnesteem information in two languages.
6. The booklet for patients who can become pregnant, Contraception Counseling Guide , includes a referral program that offers patients free contraceptioncounseling, reimbursed by the manufacturer, by a reproductive specialist, and a second Patient Enrollment Form for Patients who can get Pregnant concerningbirth defects.
7. The Guide for Patients Who Can Get Pregnant outlines the effectiveness of the approved contraception options (see Information For Patients).

General

Although an effect of Amnesteem on bone loss is not established, physicians should use caution when prescribing Amnesteem to patients with a genetic predispositionfor age related osteoporosis, a history of childhood osteoporosis conditions, osteomalacia, or other disorders of bone metabolism. This would include patients diagnosedwith anorexia nervosa and those who are on chronic drug therapy that causes drug-induced osteoporosis/osteomalacia and/or affects vitamin D metabolism, such assystemic corticosteroids and any anticonvulsant.

Patients may be at increased risk when participating in sports with repetitive impact where the risks of spondylolisthesis with and without pars fractures and hip growthplate injuries in early and late adolescence are known. There are spontaneous reports of fractures and/or delayed healing in patients while on therapy with Amnesteemor following cessation of therapy with Amnesteem while involved in these activities. While causality to Amnesteem has not been established, an effect must not beruled out.

Information For Patients

See PRECAUTIONS and BOX WARNING.

• Patients must be instructed to read the Medication Guide supplied as required by law when Amnesteem is dispensed. The complete text of the Medication Guideis reprinted at the end of this document. For additional information, patients must also be instructed to read the iPLEDGE REMS patient educational materials.All patients must sign the Patient Enrollment Form for Patients who cannot get Pregnant.
• Patients who can become pregnant must be instructed that they must not be pregnant when Amnesteem therapy is initiated, and that they should use two forms ofeffective contraception simultaneously for one month before starting Amnesteem, while taking Amnesteem, and for one month after Amnesteem has beenstopped, unless they commit to continuous abstinence from not having any sexual contact with a partner that could result in pregnancy. They should also sign asecond Patient Enrollment Form for Patients who can get Pregnant prior to beginning Amnesteem therapy. Patients who can become pregnant should be seen by their prescribers monthly and have a urine or serum pregnancy test, in a CLIA-certified laboratory, performed each month during treatment to confirm negativepregnancy status before another Amnesteem prescription is written (see BOX WARNINGand PRECAUTIONS).
• Amnesteem is found in the semen of male patients taking Amnesteem, but the amount delivered to a patient who can become pregnant would be about onemillion times lower than an oral dose of 40 mg. While the no-effect limit for isotretinoin induced embryopathy is unknown, 20 years of post-marketing reportsinclude four with isolated defects compatible with features of retinoid exposed fetuses; however two of these reports were incomplete, and two had other possibleexplanations for the defects observed.
• Prescribers should be alert to the warning signs of psychiatric disorders to guide patients to receive the help they need. Therefore, prior to initiation of Amnesteemtreatment, patients and family members should be asked about any history of psychiatric disorder, and at each visit during treatment patients should be assessedfor symptoms of depression, mood disturbance, psychosis, or aggression to determine if further evaluation may be necessary. Signs and symptoms of depressioninclude sad mood, hopelessness, feelings of guilt, worthlessness or helplessness, loss of pleasure or interest in activities, fatigue, difficulty concentrating,change in sleep pattern, change in weight or appetite, suicidal thoughts or attempts, restlessness, irritability, acting on dangerous impulses, andpersistent physical symptoms unresponsive to treatment. Patients should stop Amnesteem and the patient or a family member should promptly contact theirprescriber if the patient develops depression, mood disturbance, psychosis, or aggression, without waiting until the next visit. Discontinuation of Amnesteemtreatment may be insufficient; further evaluation may be necessary. While such monitoring may be helpful, it may not detect all patients at risk. Patients mayreport mental health problems or family history of psychiatric disorders. These reports should be discussed with the patient and/or the patient’s family. A referralto a mental health professional may be necessary. The physician should consider whether Amnesteem therapy is appropriate in this setting; for some patients therisks may outweigh the benefits of Amnesteem therapy.
• Patients must be informed that some patients, while taking Amnesteem or soon after stopping Amnesteem, have become depressed or developed other seriousmental problems. Symptoms of depression include sad, “anxious” or empty mood, irritability, acting on dangerous impulses, anger, loss of pleasure or interest insocial or sports activities, sleeping too much or too little, changes in weight or appetite, school or work performance going down, or trouble concentrating. Somepatients taking Amnesteem have had thoughts about hurting themselves or putting an end to their own lives (suicidal thoughts). Some people tried to end theirown lives. And some people have ended their own lives. There were reports that some of these people did not appear depressed. There have been reports ofpatients on Amnesteem becoming aggressive or violent. No one knows if isotretinoin caused these behaviors or if they would have happened even if the persondid not take Amnesteem. Some people have had other signs of depression while taking Amnesteem.
• Patients must be informed that they must not share Amnesteem with anyone else because of the risk of birth defects and other serious adverse events.
• Patients must be informed not to donate blood during therapy and for one month following discontinuation of the drug because the blood might be given to apregnant patient whose fetus must not be exposed to Amnesteem.
• Patients should be reminded to take Amnesteem with a meal (see DOSAGE AND ADMINISTRATION). To decrease the risk of esophageal irritation, patientsshould swallow the capsules with a full glass of liquid.
• Patients should be informed that transient exacerbation (flare) of acne has been seen, generally during the initial period of therapy.
• Wax epilation and skin resurfacing procedures (such as dermabrasion, laser) should be avoided during Amnesteem therapy and for at least 6 months thereafter dueto the possibility of scarring (see ADVERSE REACTIONS: Skin And Appendages).
• Patients should be advised to avoid prolonged exposure to UV rays or sunlight.
• Patients should be informed that they may experience decreased tolerance to contact lenses during and after therapy.
• Patients should be informed that approximately 16% of patients treated with Amnesteem in a clinical trial developed musculoskeletal symptoms (includingarthralgia) during treatment. In general, these symptoms were mild to moderate, but occasionally required discontinuation of the drug. Transient pain in the chesthas been reported less frequently. In the clinical trial, these symptoms generally cleared rapidly after discontinuation of Amnesteem, but in some cases persisted(see ADVERSE REACTIONS: Musculoskeletal). There have been rare post-marketing reports of rhabdomyolysis, some associated with strenuous physicalactivity (see Laboratory Tests: CPK).
• Pediatric patients and their caregivers should be informed that approximately 29% (104/358) of pediatric patients treated with Amnesteem developed back pain.Back pain was severe in 13.5% (14/104) of the cases and occurred at a higher frequency in female patients than male patients. Arthralgias were experienced in22% (79/358) of pediatric patients. Arthralgias were severe in 7.6% (6/79) of patients. Appropriate evaluation of the musculoskeletal system should be done inpatients who present with these symptoms during or after a course of Amnesteem. Consideration should be given to discontinuation of Amnesteem if anysignificant abnormality is found.
• Neutropenia and rare cases of agranulocytosis have been reported. Amnesteem should be discontinued if clinically significant decreases in white cell countsoccur.
• Patients should be advised that severe skin reactions (Stevens-Johnson syndrome and toxic epidermal necrolysis) have been reported in post-marketing data.Amnesteem should be discontinued if clinically significant skin reactions occur.

Hypersensitivity

Anaphylactic reactions and other allergic reactions have been reported. Cutaneous allergic reactions and serious cases of allergic vasculitis, often with purpura (bruisesand red patches) of the extremities and extracutaneous involvement (including renal) have been reported. Severe allergic reaction necessitates discontinuation of therapyand appropriate medical management.

Laboratory Tests

Pregnancy Test

• Patients who can become pregnant must have had two negative urine or serum pregnancy tests with a sensitivity of at least 25 mIU/mL before receiving the initialAmnesteem prescription. The first test (a screening test) is obtained by the prescriber when the decision is made to pursue qualification of the patient forAmnesteem. The second pregnancy test (a confirmation test) must be done in a CLIA-certified laboratory. The interval between the two tests must be at least 19days.
• For patients with regular menstrual cycles, the second pregnancy test must be done during the first 5 days of the menstrual period immediately preceding thebeginning of Amnesteem therapy and after the patient has used 2 forms of contraception for one month.
• For patients with amenorrhea, irregular cycles, or using a contraceptive method that precludes withdrawal bleeding, the second pregnancy test must be doneimmediately preceding the beginning of Amnesteem therapy and after the patient has used 2 forms of contraception for one month.
• Each month of therapy, patients must have a negative result from a urine or serum pregnancy test. A pregnancy test must be repeated each month, in a CLIA-certified laboratory, prior to the patient who can become pregnant receiving each prescription.

Lipids

Pretreatment and follow-up blood lipids should be obtained under fasting conditions. After consumption of alcohol, at least 36 hours should elapse before thesedeterminations are made. It is recommended that these tests be performed at weekly or biweekly intervals until the lipid response to Amnesteem is established. Theincidence of hypertriglyceridemia is one patient in four on Amnesteem therapy (see WARNINGS: Lipids).

Liver Function Tests

Since elevations of liver enzymes have been observed during clinical trials, and hepatitis has been reported, pretreatment and follow-up liver function tests should beperformed at weekly or biweekly intervals until the response to Amnesteem has been established (see WARNINGS: Hepatotoxicity).

Glucose

Some patients receiving Amnesteem have experienced problems in the control of their blood sugar. In addition, new cases of diabetes have been diagnosed during Amnesteem therapy, although no causal relationship has been established.

CPK

Some patients undergoing vigorous physical activity while on Amnesteem therapy have experienced elevated CPK levels; however, the clinical significance isunknown. There have been rare post-marketing reports of rhabdomyolysis, some associated with strenuous physical activity. In a clinical trial of 217 pediatric patients(12 to 17 years) with severe recalcitrant nodular acne, transient elevations in CPK were observed in 12% of patients, including those undergoing strenuous physicalactivity in association with reported musculoskeletal adverse events such as back pain, arthralgia, limb injury, or muscle sprain. In these patients, approximately half ofthe CPK elevations returned to normal within 2 weeks and half returned to normal within 4 weeks. No cases of rhabdomyolysis were reported in this trial.

Carcinogenesis, Mutagenesis, Impairment Of Fertility

In male and female Fischer 344 rats given oral isotretinoin at dosages of 8 or 32 mg/kg/day (1.3 to 5.3 times the recommended clinical dose of 1 mg/kg/day,respectively, after normalization for total body surface area) for greater than 18 months, there was a dose related increased incidence of pheochromocytoma relative tocontrols. The incidence of adrenal medullary hyperplasia was also increased at the higher dosage in both sexes. The relatively high level of spontaneouspheochromocytomas occurring in the male Fischer 344 rat makes it an equivocal model for study of this tumor; therefore, the relevance of this tumor to the humanpopulation is uncertain.

The Ames test was conducted with isotretinoin in two laboratories. The results of the tests in one laboratory were negative while in the second laboratory a weaklypositive response (less than 1.6 x background) was noted in S. typhimurium TA100 when the assay was conducted with metabolic activation. No dose-response effectwas seen and all other strains were negative. Additionally, other tests designed to assess genotoxicity (Chinese hamster cell assay, mouse micronucleus test, S.cerevisiae D7 assay, in vitro clastogenesis assay with human-derived lymphocytes, and unscheduled DNA synthesis assay) were all negative.

In rats, no adverse effects on gonadal function, fertility, conception rate, gestation or parturition were observed at oral dosages of isotretinoin of 2, 8, or 32 mg/kg/day(0.3, 1.3, or 5.3 times the recommended clinical dose of 1 mg/kg/day, respectively, after normalization for total body surface area).

In dogs, testicular atrophy was noted after treatment with oral isotretinoin for approximately 30 weeks at dosages of 20 or 60 mg/kg/day (10 or 30 times therecommended clinical dose of 1 mg/kg/day, respectively, after normalization for total body surface area). In general, there was microscopic evidence for appreciabledepression of spermatogenesis but some sperm were observed in all testes examined and in no instance were completely atrophic tubules seen. In studies of 66 men, 30of whom were patients with nodular acne under treatment with oral isotretinoin, no significant changes were noted in the count or motility of spermatozoa in theejaculate. In a study of 50 men (ages 17 to 32 years) receiving Amnesteem therapy for nodular acne, no significant effects were seen on ejaculate volume, sperm count,total sperm motility, morphology or seminal plasma fructose.

Pregnancy

Category X

See BOX WARNING.

Nursing Mothers

It is not known whether this drug is excreted in human milk. Because of the potential for adverse effects, nursing mothers should not receive Amnesteem.

Pediatric Use

The use of Amnesteem in pediatric patients less than 12 years of age has not been studied. The use of Amnesteem for the treatment of severe recalcitrant nodular acnein pediatric patients ages 12 to 17 years should be given careful consideration, especially for those patients where a known metabolic or structural bone disease exists(see PRECAUTIONS: General). Use of Amnesteem in this age group for severe recalcitrant nodular acne is supported by evidence from a clinical study comparing 103pediatric patients (13 to 17 years) to 197 adult patients (≥ 18 years). Results from this study demonstrated that Amnesteem, at a dose of 1 mg/kg/day given in twodivided doses, was equally effective in treating severe recalcitrant nodular acne in both pediatric and adult patients.

In studies with Amnesteem, adverse reactions reported in pediatric patients were similar to those described in adults except for the increased incidence of back pain andarthralgia (both of which were sometimes severe) and myalgia in pediatric patients (see ADVERSE REACTIONS).

In an open-label clinical trial (N = 217) of a single course of therapy with Amnesteem for severe recalcitrant nodular acne, bone density measurements at severalskeletal sites were not significantly decreased (lumbar spine change > -4% and total hip change > -5%) or were increased in the majority of patients. One patient had adecrease in lumbar spine bone mineral density > 4% based on unadjusted data. Sixteen (7.9%) patients had decreases in lumbar spine bone mineral density > 4%, andall the other patients (92%) did not have significant decreases or had increases (adjusted for body mass index). Nine patients (4.5%) had a decrease in total hip bonemineral density > 5% based on unadjusted data. Twenty-one (10.6%) patients had decreases in total hip bone mineral density > 5%, and all the other patients (89%) didnot have significant decreases or had increases (adjusted for body mass index). Follow-up studies performed in eight of the patients with decreased bone mineral densityfor up to 11 months thereafter demonstrated increasing bone density in five patients at the lumbar spine, while the other three patients had lumbar spine bone densitymeasurements below baseline values. Total hip bone mineral densities remained below baseline (range –1.6% to –7.6%) in five of eight patients (62.5%).

In a separate open-label extension study of ten patients, ages 13 to 18 years, who started a second course of Amnesteem 4 months after the first course, two patientsshowed a decrease in mean lumbar spine bone mineral density up to 3.25% (see WARNINGS: Skeletal: Bone Mineral Density).

Geriatric Use

Clinical studies of isotretinoin did not include sufficient numbers of subjects aged 65 years and over to determine whether they respond differently from youngersubjects. Although reported clinical experience has not identified differences in responses between elderly and younger patients, effects of aging might be expected toincrease some risks associated with isotretinoin therapy (see WARNINGS and PRECAUTIONS).

Overdose Information for Amnesteem Capsules

The oral LD₅₀ of isotretinoin is greater than 4000 mg/kg in rats and mice (> 600 times the recommended clinical dose of 1 mg/kg/day after normalization of the rat dosefor total body surface area and > 300 times the recommended clinical dose of 1 mg/kg/day after normalization of the mouse dose for total body surface area) and isapproximately 1960 mg/kg in rabbits (653 times the recommended clinical dose of 1 mg/kg/day after normalization for total body surface area). In humans, overdosagehas been associated with vomiting, facial flushing, cheilosis, abdominal pain, headache, dizziness, and ataxia. These symptoms quickly resolve without apparentresidual effects.

Amnesteem causes life threatening birth defects at any dosage (see BOX WARNING). Patients who can become pregnant whopresent with isotretinoin overdose must be evaluated for pregnancy. Patients who are pregnant should receive counseling about the risks to the fetus, as described in the BOX WARNING. Non-pregnant patients must be warned to avoid pregnancy for at least one month and receive contraceptivecounseling as described in PRECAUTIONS. Educational materials for such patients can be obtained by calling the manufacturer. Because an overdose would beexpected to result in higher levels of isotretinoin in semen than found during a normal treatment course, male patients should use a condom, or avoid reproductivesexual activity with a patient who is or might become pregnant, for one month after the overdose. All patients with isotretinoin overdose should not donate blood for atleast one month.

Contraindications for Amnesteem Capsules

Pregnancy

Category X.

See BOX WARNING.

Allergic Reactions

Amnesteem is contraindicated in patients who are hypersensitive to this medication or to any of its components (see PRECAUTIONS: Hypersensitivity).

Clinical Pharmacology for Amnesteem Capsules

Isotretinoin is a retinoid, which when administered in pharmacologic dosages of 0.5 to 1 mg/kg/day (see DOSAGE AND ADMINISTRATION), inhibits sebaceousgland function and keratinization. The exact mechanism of action of isotretinoin is unknown.

Nodular Acne

Clinical improvement in nodular acne patients occurs in association with a reduction in sebum secretion. The decrease in sebum secretion is temporary and is related tothe dose and duration of treatment with Amnesteem, and reflects a reduction in sebaceous gland size and an inhibition of sebaceous gland differentiation.¹

Pharmacokinetics

Absorption

Due to its high lipophilicity, oral absorption of isotretinoin is enhanced when given with a high-fat meal. In a crossover study, 74 healthy adult subjects received a single80 mg oral dose (2 x 40 mg capsules) of Amnesteem under fasted and fed conditions. Both peak plasma concentration (Cmax) and the total exposure (AUC) ofisotretinoin were more than doubled following a standardized high-fat meal when compared with Amnesteem given under fasted conditions (see Table 2). The observedelimination half-life was unchanged. This lack of change in half-life suggests that food increases the bioavailability of isotretinoin without altering its disposition. Thetime to peak concentration (Tmax) was also increased with food and may be related to a longer absorption phase. Therefore, Amnesteem capsules should always betaken with food (see DOSAGE AND ADMINISTRATION). Clinical studies have shown that there is no difference in the pharmacokinetics of isotretinoin betweenpatients with nodular acne and healthy subjects with normal skin.

* Eating a standardized high fat meal

Distribution

Isotretinoin is more than 99.9% bound to plasma proteins, primarily albumin.

Metabolism

Following oral administration of isotretinoin, at least three metabolites have been identified in human plasma: 4-oxo-isotretinoin, retinoic acid (tretinoin), and 4-oxo-retinoic acid (4-oxo-tretinoin). Retinoic acid and 13-cis-retinoic acid are geometric isomers and show reversible interconversion. The administration of one isomer willgive rise to the other. Isotretinoin is also irreversibly oxidized to 4-oxo-isotretinoin, which forms its geometric isomer 4-oxo-tretinoin.

After a single 80 mg oral dose of Amnesteem to 74 healthy adult subjects, concurrent administration of food increased the extent of formation of all metabolites inplasma when compared to the extent of formation under fasted conditions.

All of these metabolites possess retinoid activity that is in some in vitro models more than that of the parent isotretinoin. However, the clinical significance of thesemodels is unknown. After multiple oral dose administration of isotretinoin to adult cystic acne patients (≥ 18 years), the exposure of patients to 4-oxo-isotretinoin atsteady-state under fasted and fed conditions was approximately 3.4 times higher than that of isotretinoin.

In vitro studies indicate that the primary P450 isoforms involved in isotretinoin metabolism are 2C8, 2C9, 3A4, and 2B6. Isotretinoin and its metabolites are furthermetabolized into conjugates, which are then excreted in urine and feces.

Elimination

Following oral administration of an 80 mg dose of ¹⁴C-isotretinoin as a liquid suspension, ¹⁴C-activity in blood declined with a half-life of 90 hours. The metabolites ofisotretinoin and any conjugates are ultimately excreted in the feces and urine in relatively equal amounts (total of 65% to 83%). After a single 80 mg oral dose ofAmnesteem to 74 healthy adult subjects under fed conditions, the mean ± SD elimination half-lives (t_1/2) of isotretinoin and 4-oxo-isotretinoin were 21 ± 8.2 hours and24 ± 5.3 hours, respectively. After both single and multiple doses, the observed accumulation ratios of isotretinoin ranged from 0.9 to 5.43 in patients with cystic acne.

Special Patient Populations

Pediatric Patients

The pharmacokinetics of isotretinoin were evaluated after single and multiple doses in 38 pediatric patients (12 to 15 years) and 19 adult patients (≥ 18 years) whoreceived Amnesteem for the treatment of severe recalcitrant nodular acne. In both age groups, 4-oxo-isotretinoin was the major metabolite; tretinoin and 4-oxo-tretinoinwere also observed. The dose-normalized pharmacokinetic parameters for isotretinoin following single and multiple doses are summarized in Table 3 for pediatricpatients. There were no statistically significant differences in the pharmacokinetics of isotretinoin between pediatric and adult patients.

What is Amnesteem?

Amnesteem is a medicine taken by mouth to treat the most severe form of acne (nodular acne) that cannot be cleared up by any other acne treatments, includingantibiotics. Amnesteem can cause serious side effects (see “What is the most important information I should know about Amnesteem?” ). Amnesteem can only be:

• prescribed by doctors that are enrolled in the iPLEDGE REMS
• dispensed by a pharmacy that is enrolled with the iPLEDGE REMS
• given to patients who are enrolled in the iPLEDGE REMS and agree to do everything required in the program.

What is severe nodular acne?

Severe nodular acne is when many red, swollen, tender lumps form in the skin. These can be the size of pencil erasers or larger. If untreated, nodular acne can lead topermanent scars.

Who should not take Amnesteem?

• Do not take Amnesteem if you are pregnant, plan to become pregnant, or become pregnant during Amnesteem treatment. Amnesteem causes lifethreatening birth defects. See “What is the most important information I should know about Amnesteem?”
• Do not take Amnesteem if you are allergic to anything in it. See the end of this Medication Guide for a complete list of ingredients in Amnesteem.

What should I tell my doctor before taking Amnesteem?

Tell your doctor if you or a family member has any of the following health conditions:

• mental problems
• asthma
• liver disease
• diabetes
• heart disease
• bone loss (osteoporosis) or weak bones
• an eating problem called anorexia nervosa (where people eat too little)
• food or medicine allergies

Tell your doctor if you are pregnant or breast-feeding. Amnesteem must not be used by patients who are pregnant or breast-feeding.

Tell your doctor about all of the medicines you take including prescription and non-prescription medicines, vitamins and herbal supplements. Amnesteem andcertain other medicines can interact with each other, sometimes causing serious side effects. Especially tell your doctor if you take:

• Vitamin A supplements. Vitamin A in high doses has many of the same side effects as Amnesteem. Taking both together may increase your chance of gettingside effects.
• Tetracycline antibiotics. Tetracycline antibiotics taken with Amnesteem can increase the chances of getting increased pressure in the brain.
• Progestin-only birth control pills (mini-pills). They may not work while you take Amnesteem. Ask your doctor or pharmacist if you are not sure what type youare using.
• Dilantin (phenytoin). This medicine taken with Amnesteem may weaken your bones.
• Corticosteroid medicines. These medicines taken with Amnesteem may weaken your bones.
• St. John’s Wort. This herbal supplement may make birth control pills work less effectively.

These medicines should not be used with Amnesteem unless your doctor tells you it is okay.

Know the medicines you take. Keep a list of them to show to your doctor and pharmacist. Do not take any new medicine without talking with your doctor.

How should I take Amnesteem?
