Neomycin — Uses, Dosage, Side Effects & Safety

Drug class: Aminoglycoside Antibiotic

Overview

Neomycin is an aminoglycoside antibiotic used to treat a variety of bacterial infections. It is most commonly used topically for skin infections, and orally to reduce bacteria in the intestines before surgery or to manage hepatic encephalopathy. Neomycin works by stopping the growth of bacteria, helping your body fight off infection. When used orally, neomycin is not absorbed well into the bloodstream, so it mainly acts in the gut. This makes it useful for decreasing intestinal bacteria before certain surgeries or in specific liver conditions. Patients should be aware that neomycin is not effective against viral infections (such as the common cold or flu) and should only be used as prescribed by a healthcare provider.
