Neomycin may cause permanent hearing loss, nerve damage, and severe kidney damage. Hearing loss can occur even after the drug is stopped. If you already have kidney problems or hearing difficulty, tell your doctor. Notify your doctor immediately if any of the following occur: ringing in your ears, hearing loss, unusual tingling, muscle twitching, seizures. Neomycin may be stopped if you develop kidney or hearing problems. Your doctor will monitor your progress to minimize the possibility of these effects occurring and may run certain tests (eg, hearing and/or kidney tests). Do not use Neomycin with other medicines that can cause nerve, kidney, or hearing problems. Other factors that increase the risk of these side effects occurring include advanced age or dehydration (unusual thirst).
Neomycin may also cause severe muscle relaxation progressing to paralysis and breathing problems. This possibility increases if you are also taking anesthetics, neuromuscular-blocking agents (eg, succinylcholine), or if you are receiving massive transfusions of citrate anticoagulated blood. Use with other aminoglycosides (eg, paromomycin) or other nephrotoxic/neurotoxic medicines (eg, bacitracin), advanced age, and dehydration all increase the risk of side effects. Potent diuretics (eg, ethacrynic acid, furosemide) should also be avoided because they can cause hearing loss.
