Effects of drug abuse
- See “What are Side Effects Associated with Using Amikacin?”
- See “What Are Side Effects Associated with Using Amikacin?”
- 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
