Warnings for ACUVUE Theravision with Ketotifen
Included as part of the PRECAUTIONS section.
Precautions for ACUVUE Theravision with Ketotifen
Corneal Ulcers
ACUVUE Theravision with Ketotifen should not be inserted if the patient has corneal epithelial breakdown, corneal ulceration, dry eye disease, injury or abnormality that affects the eyelids or anterior segment of the eye. Contact lens wear may worsen these conditions and lead to sight threatening complications. If a patient experiences eye discomfort, excessive tearing, vision changes, or redness of the eye, the patient should be instructed to immediately remove the lenses, and promptly contact the Eye Care Professional.
Studies have shown that when daily wear users wear their lenses overnight, the risk of ulcerative keratitis is greater than among those who do not wear them overnight. Contact lens wearers who are smokers have a higher incidence of corneal ulcers than nonsmokers.
Contact Lens-Related Complications
ACUVUE Theravision with Ketotifen should not be used to treat or prevent lens-related symptoms including irritation, discomfort or redness. ACUVUE Theravision with Ketotifen insertion could result in serious injury if a patient is experiencing these symptoms. Patients should be cautioned that proper use and care of contact lenses and lens care products are essential for the safe use of these products. If patients experience symptoms of contact lens intolerance or keratitis, the lens(es) should be IMMEDIATELY REMOVED.
Chemical Exposures
If chemicals of any kind (household products, gardening solutions, laboratory chemicals, etc.) are splashed into the eyes, the patient should: FLUSH EYES IMMEDIATELY WITH WATER AND IMMEDIATELY CONTACT THE EYE CARE PROFESSIONAL OR VISIT A HOSPITAL EMERGENCY ROOM WITHOUT DELAY.
Acanthamoeba Keratitis
ACUVUE Theravision with Ketotifen should not be worn while swimming or in hot tubs. The lens should not be rinsed in water from the tap. Tap water contains many impurities that can contaminate or damage the lenses and may lead to eye infection or injury. Contact lens wear in these settings increases the risk of sight threatening eye infections from microorganisms.
Backup Spectacles
Eye Care Professionals should instruct the patient to always have a functional pair of spectacles with a current prescription available to use if the patient becomes unable to wear contact lenses, or in circumstances where contact lens wear is not advised.
Eye Protection
Patients should be advised to notify the employer of being a contact lens wearer. Some jobs may require the use of eye protection equipment or may require that the patient not wear contact lenses.
Concomitant Use Of Eye Drops Or Eye Medications
Eye drops or Eye Medications containing benzalkonium chloride should not be used simultaneously with ACUVUE Theravision with Ketotifen. Wait at least 10 minutes after eye drop application before inserting lenses.
Patient Counseling Information

Nonclinical Toxicology
Carcinogenesis, Mutagenesis, Impairment Of Fertility
Carcinogenesis
No information is available on the carcinogenic potential of ketotifen fumarate.
Mutagenesis
Ketotifen fumarate was determined to be non-mutagenic in a battery of in vitro and in vivo mutagenicity assays including: Ames test, in vitro chromosomal aberration test with V79 Chinese hamster cells, in vivo micronucleus assay in mouse, and mouse dominant lethal test. In addition, extracts of etafilcon A with ketotifen (19 mcg/lens) prepared in 0.9% sodium chloride or dimethyl sulfoxide were shown to be non-mutagenic in the Ames test.
Impairment Of Fertility
Treatment of male rats with oral doses of ketotifen >10 mg/kg/day (approximately 2,600 times the MRHOD) for 70 days prior to mating resulted in mortality and a decrease in fertility. Treatment with ketotifen did not impair fertility in female rats receiving up to 50 mg/kg/day of ketotifen orally (approximately 13,000 times the MRHOD) for 15 days prior to mating.
Use In Specific Populations
Pregnancy
Risk Summary
There are no adequate and well-controlled studies of ACUVUE® Theravison™ with Ketotifen administration in pregnant women to inform a drug-associated risk. ACUVUE® Theravison™ with Ketotifen is not absorbed systemically following ocular administration, and maternal use is not expected to result in fetal exposure to the drug. Oral administration of ketotifen fumarate to pregnant rats or rabbits did not produce teratogenicity at clinically relevant doses [see Data].
Data
Human Data
There are no human data that establish the presence or absence of drug-associated risk with the use of ACUVUE® Theravision™ with Ketotifen by pregnant women.
Animal Data
Oral administration of 45 mg/kg/day ketotifen to pregnant rabbits resulted in an increased incidence of retarded ossification of the sternebrae. This dose (normalized to body surface area) was approximately 23,000 times higher than the daily maximum recommended human ophthalmic dose (MRHOD) of 0.038 mg.
No adverse embryofetal effects were observed in rats or rabbits orally administered 100 mg/kg/day and 15 mg/kg/day, respectively, during organogenesis. These doses (normalized to body surface area) were approximately 26,000 and 7,700 times higher than the MRHOD, respectively.
An oral dose of 50 mg/kg/day ketotifen (approximately 13,000 times higher than MRHOD) administered to rats from Day 15 of pregnancy until Day 21 postpartum produced maternal toxicity, a slight increase in postnatal mortality and a slight decrease in body weight gain in offspring during the first four days post-partum.
Lactation
Risk Summary
There is no information regarding the presence or absence of ketotifen fumarate or its metabolites in human milk following use of ACUVUE® Theravision™ with Ketotifen, or on the breastfed infants and milk production. Ketotifen fumarate has been identified in breast milk in rats following oral administration. It is not known whether topical ocular administration could result in sufficient systemic absorption to produce detectable quantities in breast milk. The development and health benefits of breastfeeding should be considered along with the mother’s clinical need for ACUVUE® Theravision™ with Ketotifen and any potential adverse effects on the breast-fed child from ketotifen fumarate.
Pediatric Use
The safety and efficacy of ACUVUE® Theravision™ with Ketotifen in pediatric patients below the age of 11 years has not been established.
Geriatric Use
Clinical studies of etafilcon A with ketotifen did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.
Overdose Information for ACUVUE Theravision with Ketotifen
No Information provided
Contraindications for ACUVUE Theravision with Ketotifen
Ocular Hyperemia
ACUVUE Theravision with Ketotifen is contraindicated in patients with ocular hyperemia and should not be inserted into red or irritated eye(s). Remove ACUVUE Theravision with Ketotifen immediately if eye(s) becomes red or irritated.
Corneal Hypoesthesia
ACUVUE Theravision with Ketotifen is contraindicated in patients with decreased corneal sensation.
Corneal Infections
ACUVUE Theravision with Ketotifen is contraindicated in patients with any corneal infection (bacterial, fungal, protozoal or viral).
Clinical Pharmacology for ACUVUE Theravision with Ketotifen
Mechanism Of Action
Device Component
In its hydrated state, the lens when placed on the cornea, acts as a refracting medium to focus light rays on the retina to correct refractive ametropia for as long as the lens is worn (up to 24 hours while awake).
Drug Component
Ketotifen fumarate, a benzocycloheptathiophene derivative, is a H1 receptor antagonist that stabilizes mast cells and prevents eosinophil accumulation. This action prevents the onset of ocular allergic itch allowing for continued lens wear during episodes of allergen exposure and has been demonstrated to last through 12 hours.
Clinical Studies
The safety and efficacy of ACUVUE® Theravision™ with Ketotifen was assessed in two double-masked, randomized, placebo-controlled clinical conjunctival allergen challenge (CAC) studies (CR-4483 and CR-4484) and two 12-week safety studies (CR-4490 and CR-4539). Patients in these studies had allergic conjunctivitis induced by an ocular allergen challenge and refractive ametropia (myopia and hyperopia) suitable for contact lens wear without more than 1.00 D of astigmatism. A total of 244 patients (488 eyes) were evaluated in the CAC studies. A total of 491 subjects were exposed to ACUVUE® Theravision™ with Ketotifen over a period of 12 weeks in the safety studies. These four studies demonstrated that ACUVUE® Theravision™ with Ketotifen was safe and more effective than placebo (1•DAY ACUVUE®) in preventing ocular itching in patients with allergic conjunctivitis. ACUVUE® Theravision™ with Ketotifen reduced ocular itching within 3 minutes and the response was sustained for up to 12 hours after lens insertion. Visual acuity was comparable between ACUVUE® Theravision™ with Ketotifen and 1•DAY ACUVUE®.
Not all refractive powers, design configurations, or lens parameters available were tested in clinical investigation of the lenses. Therefore, when selecting an appropriate lens design, the Eye Care Professional should consider all characteristics of the lens that can affect lens performance and ocular health, including oxygen permeability, wettability, central and peripheral thickness and optic zone diameter. The potential impact of these factors on the patient's ocular health should be carefully weighed against the patient's need for refractive correction and prevention of itching associated with allergic conjunctivitis; therefore, the continuing ocular health of the patient and lens performance on the eye should be carefully monitored by the prescribing Eye Care Professional.

PRECAUTIONS
For your eye health, it is important to carefully follow the handling, insertion, removal, and wearing instructions in this booklet, as well as those prescribed by your Eye Care Professional (see “Lens Handling & Insertion”, “Lens Wearing” and “Caring for your Lenses” sections).
General Precautions
Do Not use contact lens care solutions with this product.
If you wear your contact lenses to correct presbyopia using monovision you may not be able to get the best corrected visual acuity for either far or near vision. Visual needs are different for different people, so your Eye Care Professional should work with you when selecting the most appropriate type of lens for you.
Always contact your Eye Care Professional before using any medicine in your eyes.
Be aware that certain medications, such as antihistamines, decongestants, diuretics, muscle relaxants, tranquilizers, oral contraceptives, and those for motion sickness may cause dryness of the eye, increased lens awareness (feeling of the lens in the eye), or blurred vision. Always inform your Eye Care Professional if you experience any problems with your lenses while taking such medications.
Do not change lens type (e.g. brand name, etc.) or parameters (e.g. diameter, base curve, lens power, etc.) without consulting your Eye Care Professional.
Consult your Eye Care Professional or Health Care Provider if you are pregnant or nursing a baby.
As with any contact lens, follow-up visits are necessary to assure the continuing health of your eyes. Ask your Eye Care Professional about the recommended follow-up schedule.
Who Should Know That You are Wearing Contact Lenses:
Inform all of your doctors (Health Care Professionals) about being a contact lens wearer.
Always inform your employer of being a contact lens wearer. Some jobs may require use of eye protection equipment or may require that you not wear contact lenses.
ADVERSE REACTIONS (POSSIBLE PROBLEMS WITH LENS WEAR AND WHAT TO DO)
Possible Problems

When any of the above symptoms occur, a serious eye condition may be present. You should immediately be seen by your Eye Care Professional, so that the problem can be identified and treated, if necessary, in order to avoid serious eye damage.
This product should not be used to treat or prevent lens-related symptoms including irritation, discomfort, or redness.
Recognizing Problems and What To Do
You should conduct a simple 3-part self-examination at least once a day. Ask yourself:
- How do the lenses feel on my eyes?
- How do my eyes look?
- Have I noticed a change in my vision?
If you notice any problems, you should IMMEDIATELY REMOVE YOUR LENS AND CONTACT YOUR EYE CARE PROFESSIONAL.
LENS HANDLING AND INSERTION
For your eye health, it is important to carefully follow the handling, insertion, removal, and wearing instructions in this booklet, as well as those prescribed by your Eye Care Professional. If you will not or cannot always follow the recommended care procedures, you should not attempt to wear contact lenses.
When you first get your lenses, be sure that you are able to put the lenses on and remove them (or have someone else available who can remove the lenses for you) before leaving your Eye Care Professional’s office.
Step 1: Getting Started
It is essential that you learn and use good hygiene in the care and handling of your new lenses.
Cleanliness is the first and most important aspect of proper contact lens care. In particular, your hands should be clean, dry, and free of any soaps, lotions, or creams before you handle your lenses.
Before you start:
Always wash your hands thoroughly with a mild soap, rinse completely, and dry with a lint-free towel before touching your lenses.
You should avoid the use of soaps containing cold cream, lotion, or cosmetics before handling your lenses. These substances may come into contact with the lenses and interfere with successful wearing. It is best to put on your lenses before putting on makeup
Step 2: Opening the Packaging
Multi-pack
Always confirm the lens parameters (e.g. diameter (DIA), base curve (BC), lens power (D), etc.) printed on the multi-pack and on the individual lens package match your prescription. DO NOT use if there is a mismatch.
Each multi-pack contains individually packaged lenses. Each lens comes in its own lens package designed specifically to keep it sterile while sealed.
These lenses are sensitive to light – store individual blister packages in the carton until use.
Lens Package
DO NOT use if the sterile blister package is opened or damaged.
To open an individual lens package, follow these simple steps:
- Shake the lens package and check to see that the lens is floating in the solution.
- Carefully peel back the foil closure to reveal the lens.
- Place a finger on the lens and slide the lens up the side of the bowl of the lens package until it is free of the container.
Occasionally, a lens may stick to the inside surface of the foil when opened, or to the plastic package itself. This will not affect the sterility of the lens. It is still perfectly safe to use. Carefully remove and inspect the lens following the handling instructions.
NEVER use tweezers or other tools to remove your lenses from the lens container.
Lens Handling Tips
- Handle your lenses with your fingertips, and be careful to avoid contact with fingernails. It is helpful to keep your fingernails short and smooth.
- Develop the habit of always working with the same lens first to avoid mix-ups.
- After you have removed the lens from the packaging, examine it to be sure that it is a single, moist, clean lens that is free of any nicks or tears. If the lens appears damaged, DO NOT use it.
Step 3: Placing the Lens on the Eye
Remember, always start with the same eye.
Once you have opened the lens package, removed, and examined the lens, follow these steps to insert the lens into your eye:
- BE SURE THE LENS IS NOT INSIDE-OUT by following one of the following procedures:
- Place the lens on the tip of your index finger and check its profile. The lens should assume a natural, curved, bowl-like shape. If the lens edges tend to point outward, the lens is inside out.
- Gently squeeze the lens between the thumb and forefinger. The edges should turn inward. If the lens is inside out, the edges will turn slightly outward. OR
- Place the lens on the tip of your index finger and, looking up at the lens, locate the numbers 1-2-3. 1-23 indicates correct orientation, while a reverse of 1-2-3 indicates the lens is inside out. If the lens is inside out (reverse 1-2-3), invert the lens and locate the numbers again to confirm correct lens orientation.
- With the lens on your index finger, use your other hand to hold your upper eyelid so you won’t blink.
- Pull down your lower eyelid with the other fingers of your “inserting” hand.
- Look up at the ceiling and gently place the lens on the lower part of your eye.
- Slowly release your eyelid and close your eye for a moment.
- Blink several times to center the lens.
- Use the same technique when inserting the lens for your other eye.
There are other methods of lens placement. If the above method is difficult for you, ask your Eye Care Professional for an alternate method.
Step 4: Checking Your Lenses
After you have successfully inserted your lenses, you should ask yourself:
- Do I see well?
- How do the lenses feel on my eyes?
- How do my eyes look?
If after placement of the lens, your vision is blurred, check for the following:
The lens is not centered on the eye (see “Step 5: Centering the Lens,” next in this booklet).
If the lens is centered, remove the lens (see “Removing Your Lenses”) and check for the following:
- Cosmetics or oils on the lens. Dispose of the lens and insert a new fresh lens.
- The lens is on the wrong eye.
- The lens is inside out (it would also not be as comfortable as normal). See “Step 3: Placing the Lens on the Eye.”
If you find that your vision is still blurred after checking the above possibilities, remove the lens and consult your Eye Care Professional.
Note: If a lens is noticeably uncomfortable upon insertion or becomes less comfortable than when it was first inserted, remove the lens immediately and contact your Eye Care Professional. If your examination of your eyes and the lenses shows any other problems, IMMEDIATELY REMOVE YOUR LENSES AND CONTACT YOUR EYE CARE PROFESSIONAL.
Step 5: Centering the Lens
A lens, which is on the cornea (center of your eye), will very rarely move onto the white part of the eye during wear. This, however, can occur if insertion and removal procedures are not performed properly. To center a lens, follow either of these procedures:
- Close your eyelids and gently massage the lens into place through the closed lids. OR
- Gently move the off-centered lens onto the cornea (center of your eye) while the eye is opened using finger pressure on the edge of the upper lid or lower lid.
LENS WEARING
While wearing your lenses, remember the following important precautions:
Hazardous Conditions
If you use aerosol (spray) products, such as hair-spray, while wearing lenses, keep your eyes closed until the spray has settled.
Avoid all harmful or irritating vapors and fumes while wearing lenses.
Never rinse your lenses in water from the tap. Tap water contains many impurities that can contaminate or damage your lenses and may lead to eye infection or injury.
Water Activity
- Do not expose your contact lenses to water while you are wearing them.
Lubricating/Rewetting Solutions
Lubricating/Rewetting Solutions should not be used with these lenses. If the lens sticks (stops moving), a few drops of non-preserved sterile saline may be applied to assist with removal.
Do not use saliva or anything other than the recommended solutions for lubricating or rewetting your lenses. Do not put lenses in your mouth.
Sharing Lenses
Never allow anyone else to wear your lenses. Sharing lenses greatly increases the chance of eye infections.
Adhering to the Prescribed Wearing & Replacement Schedules
Never wear your lenses beyond the amount of time recommended by your Eye Care Professional. Never wear more than one lens per day.
Always throw away worn lenses as prescribed by your Eye Care Professional.
REMOVING YOUR LENSES
CAUTION: Always be sure the lens is on the cornea (center of your eye) before attempting to remove it. Determine this by covering the other eye. If vision is blurred, the lens is either on the white part of the eye or it is not on the eye at all. To locate the lens, inspect the upper area of the eye by looking down into a mirror while pulling the upper lid up. Then inspect the lower area by pulling the lower lid down.
1. Wash, rinse, and dry your hands thoroughly. You should follow the method that is recommended by your Eye Care Professional. Below is an example of one method: the Pinch Method.
Pinch Method:
Step 1. Look up, slide the lens to the lower part of the eye using the forefinger.
Step 2. Gently pinch the lens between the thumb and forefinger.
Step 3. Remove the lens.
2. Follow the instructions in the next section, “Caring for Your Lenses”.
NOTE: For your eye health, it is important that the lens moves freely on your eye. If the lens sticks (stops moving) on your eye, apply a few drops of the recommended rewetting solution. Wait until the lens begins to move freely on the eye before removing it. If non-movement of the lens continues, you should immediately consult your Eye Care Professional.
CARING FOR YOUR LENSES
Remember, there is no cleaning or disinfection needed with these lenses. Always dispose of lenses when they are removed and have replacement non-medicated lenses or glasses available. Any unused product or waste material should be disposed of in accordance with local requirements.
Lens Storage:
- Store these lenses at room temperature.
- These lenses are sensitive to light – store individual blister packages in the carton until use.
EMERGENCIES
If chemicals of any kind (household products, gardening solutions, laboratory chemicals, etc.) are splashed into your eyes: FLUSH EYES IMMEDIATELY WITH TAP WATER AND IMMEDIATELY CONTACT YOUR EYE CARE PROFESSIONAL OR VISIT A HOSPITAL EMERGENCY ROOM RIGHT AWAY.
INSTRUCTIONS FOR THE PRESBYOPIC PATIENT
The decision to be fit with monovision correction is most appropriately left to your Eye Care Professional, in conjunction with you, after carefully considering and discussing your needs.
