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.

Warnings
This medication can rarely cause serious kidney problems and nerve damage, resulting in permanent hearing loss (including deafness or decreased hearing) and balance problems. These serious side effects may occur even in people without kidney problems and taking usual doses. Hearing problems may occur long after neomycin has been stopped.

Your risk is also increased if you receive high doses, or with longer use of this medication. Careful monitoring by your doctor (which may include hearing, kidney, and urine tests) will reduce the risk of these side effects. Avoid other medications that may increase your risk for these serious side effects if taken together with neomycin (See also Drug Interactions section). Tell your doctor right away if you notice any signs of these serious side effects, including: ringing/roaring sounds in the ears, hearing loss, dizziness, or an unusual decrease in the amount of your urine.
Severe muscle and breathing problems may also rarely occur.
