Neomycin

Pronounced

"nee-oh-MY-sin"

Common brand names:

Mycifradin

Uses

This medication is used to decrease the risk of infection after certain intestinal surgeries. Neomycin belongs to a class of drugs known as aminoglycoside antibiotics. It works by stopping the growth of bacteria in the intestines.

Neomycin may also be used along with a special diet to treat a certain serious brain problem (hepatic encephalopathy). This condition is caused by too much of a certain natural substance (ammonia). Normally, the liver gets rid of ammonia, but liver disease can cause too much ammonia to build up in the body. This medication helps treat encephalopathy by killing certain intestinal bacteria that make ammonia.

This antibiotic treats only bacterial infections. It will not work for viral infections (such as common cold, flu). Using any antibiotic when it is not needed can cause it to not work for future infections.
