The toxicity usually reverts once the antibiotic course has been completed, and can be avoided altogether by less frequent dosing (such as once every 24 hours rather than once every 8 hours).Amikacin can cause neuromuscular blockade (including acute muscular paralysis) and respiratory paralysis (including apnea).Rare side effects (occurring in fewer than 1% of users) include allergic reactions, skin rash, fever, headaches, tremor, nausea and vomiting, eosinophilia, arthralgia, anemia, hypotension, and hypomagnesemia. In intravitreous injections (where amikacin is injected into the eye), macular infarction can cause permanent vision loss.The amikacin liposome inhalation suspension prescribing information includes a boxed warning regarding the increased risk of respiratory conditions including hypersensitivity pneumonitis (inflamed lungs), bronchospasm (tightening of the airway), exacerbation of underlying lung disease and hemoptysis (spitting up blood) that have led to hospitalizations in some cases. Other common side effects in patients taking amikacin liposome inhalation suspension are dysphonia (difficulty speaking), cough, ototoxicity (damaged hearing), upper airway irritation, musculoskeletal pain, fatigue, diarrhea and nausea. Contraindications
Amikacin should be avoided in those who are sensitive to any aminoglycoside, as they are cross-allergenic (that is, an allergy to one aminoglycoside also confers hypersensitivity to other aminoglycosides). It should also be avoided in those sensitive to sulfite (seen more among people with asthma), since most amikacin usually comes with sodium metabisulfite, which can cause an allergic reaction.In general, amikacin should not be used with or just before/after another drug that can cause neurotoxicity, ototoxicity, or nephrotoxicity.
