What is neomycin?

Neomycin is a prescription drug. It comes as an oral tablet.

Neomycin oral tablet is only available as a generic drug. It doesn’t have a brand-name version.

This drug may be used as part of a combination therapy. This means you may need to take it with other medications.

Why it’s used

Neomycin oral tablet is used to prevent or treat bacterial infections in the intestines. It’s given before certain surgeries. It’s also used to treat hepatic coma, which is the loss of brain function due to a liver problem. Hepatic coma happens when your liver can’t remove ammonia from your blood.

How it works

Neomycin belongs to a class of drugs called aminoglycosides. A class of drugs is a group of medications that work in a similar way. These drugs are often used to treat similar conditions.

For people with an infection, neomycin works by killing bacteria and stopping it from growing in your body. This treats your infection or stops an infection from forming in the first place.

People with hepatic coma can’t remove ammonia from their blood. Neomycin works by killing bacteria in their gut, which releases ammonia.
