Amikacin (amikacin sulfate) — Uses, Dosage, Side Effects & Safety

Drug class: Aminoglycoside antibiotic

Overview

Amikacin is a prescription antibiotic used to treat serious bacterial infections, especially those caused by Gram-negative bacteria. It is commonly used when other antibiotics are ineffective or when infections are resistant to other drugs. Amikacin works by stopping the growth of bacteria, helping your body fight off the infection. This medication is usually given by injection in a hospital or clinic setting. It is important to complete the full course of treatment as prescribed, even if you start to feel better, to ensure the infection is fully cleared. Patients should be aware that amikacin can have serious side effects, especially affecting the ears and kidneys, so regular monitoring is necessary during treatment.
