Adjust dose based on renal function; monitor serum creatinine and trough levels; usual starting dose: 15 mg/kg/day with extended intervals per renal function.
Initiate with 0.25 mg intravenously every 6 hours; titrate cautiously due to increased sensitivity and renal impairment.
Aminoglycosides can cause nephrotoxicity and ototoxicity. Neurotoxicity (including vestibular and auditory) may occur even at normal doses. Risk is greater in patients with renal impairment, pre-existing hearing loss, or prolonged use. Monitor renal function and eighth cranial nerve function.
None
Monitor renal function and audiometric tests,Adjust dose based on renal function,Risk of neuromuscular blockade, especially in patients with neuromuscular disorders,Avoid concurrent use of other nephrotoxic or ototoxic drugs,Use caution in neonates, elderly, and patients with dehydration
Increased risk of infections due to immunosuppression,Adrenal suppression with prolonged use,Osteoporosis with long-term use,Exacerbation of diabetes mellitus,Psychiatric disturbances
Hypersensitivity to amikacin or other aminoglycosides,Myasthenia gravis (relative due to risk of neuromuscular blockade)
Systemic fungal infections,Hypersensitivity to the drug or any component,Administration of live or live attenuated vaccines
No clinically significant food interactions. Maintain adequate hydration. Avoid excessive alcohol consumption.
Avoid grapefruit and grapefruit juice as they may increase drug levels. Take with food to reduce gastrointestinal irritation. Limit sodium intake to reduce fluid retention; consider potassium-rich foods.
Aminoglycosides like amikacin cross the placenta. First trimester: No evidence of major malformations, but risk cannot be excluded. Second and third trimesters: Potential for fetal ototoxicity (eighth cranial nerve damage) and nephrotoxicity, especially with high doses or prolonged use. Avoid unless compelling indication.
ALPHADROL is contraindicated in pregnancy. First trimester exposure associated with increased risk of cleft palate, cardiac defects, and neural tube defects. Second and third trimester exposure can cause fetal growth restriction, oligohydramnios, and adrenal suppression. Risk category X.
Minimal excretion into breast milk (M/P ratio unknown but expected low). No reports of adverse effects in nursing infants from maternal amikacin use. Caution with infant renal impairment or premature infants due to potential accumulation. Use only if necessary.
Excreted into breast milk; M/P ratio not reported. Potential for infant adrenal suppression and growth retardation. Breastfeeding not recommended during therapy and for at least 3 months after last dose.
Increased renal clearance in pregnancy may lower serum levels; consider higher doses based on therapeutic drug monitoring. Adjust for renal impairment if present. Standard initial dosing: 15 mg/kg/day IV/IM divided q8-12h, with level-guided adjustments.
Avoid use in pregnancy; no established dose adjustments; use lowest effective dose if unavoidable; increased clearance may require dose increase, but teratogenicity risk precludes use.
Amikacin is an aminoglycoside antibiotic with concentration-dependent bactericidal activity. Monitor peak (20-30 mcg/m L) and trough (<10 mcg/m L) serum levels to optimize efficacy and minimize toxicity. Adjust dose based on renal function (Cr Cl). Ototoxicity (vestibular and cochlear) and nephrotoxicity are dose-limiting; audiometry and renal function tests are mandatory. Extended-interval dosing (15-20 mg/kg once daily) is preferred for most indications. Avoid concurrent use with other nephrotoxic drugs (e.g., vancomycin, loop diuretics).
Monitor blood glucose closely in diabetic patients; may cause hyperglycemia. Administer with food to reduce GI upset. Taper dose over 1-2 weeks after prolonged use to avoid adrenal insufficiency. Avoid live vaccines during therapy.

"Lithium cation may increase the excretion rate of Sodium chloride which could result in a lower serum level and potentially a reduction in efficacy."
