Neomycin

Warning

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. The risk is increased if you are older, already have kidney disease, or if you have a severe loss of body water (dehydration). 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.
