  • See “What are Side Effects Associated with Using Amikacin?”

Long-Term Effects

  • See “What Are Side Effects Associated with Using Amikacin?”

Cautions

  • Caution in patients with renal impairment
  • Not intended for long-term therapy; caution in patients with renal failure (not on dialysis), hypocalcemia, myasthenia gravis, and conditions that depress neuromuscular transmission
  • Serious and potentially life-threatening hypersensitivity reactions, including anaphylaxis, reported; before therapy instituted, evaluate for previous hypersensitivity reactions to aminoglycosides; if anaphylaxis or a hypersensitivity reaction occurs, discontinue therapy and institute appropriate supportive measures
  • Hypersensitivity pneumonitis reported; if hypersensitivity pneumonitis occurs, discontinue therapy and manage patients as medically appropriate
  • Higher frequency of hemoptysis and bronchospasm, reported with treatment; if these occur, manage patients as medically appropriate
  • Aminoglycosides can cause nephrotoxicity; close monitoring of patients with known or suspected renal dysfunction may be needed when prescribing drug
  • Higher frequency of ototoxicity reported with treatment; closely monitor patients with known or suspected auditory or vestibular dysfunction; if patients develop tinnitus this may be an early symptom of ototoxicity
  • Aminoglycosides may aggravate muscle weakness because of a potential curare-like effect on neuromuscular function; if neuromuscular blockade occurs, it may be reversed by the administration of calcium salts, but mechanical assistance may be necessary
  • Higher frequency of exacerbations of underlying pulmonary disease reported with treatment; treat patients as medically appropriate if this occurs
  • Aminoglycosides can cause total, irreversible, bilateral congenital deafness in pediatric patients exposed in utero

Pregnancy and Lactation

  • Use in life-threatening emergencies when no safer drug available.  Positive evidence of human fetal risk.  
  • Excretion in milk is unknown, not recommended.
