Generic Name: neomycin (nee-oh-MYE-sin)
Brand Name: Generic only. No brands available.
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.
Neomycin is used for:
Reducing bacteria in the intestines. It may also be used for other conditions as determined by your doctor.
Neomycin is an aminoglycoside antibiotic. It kills sensitive bacteria by stopping the production of essential proteins needed by the bacteria to survive.
Do NOT use neomycin if:
- you are allergic to any ingredient in neomycin or to any other aminoglycosides (eg, gentamicin)
- you are taking fludarabine, nondepolarizing muscle relaxants (eg, vecuronium), or penicillin
- you have intestinal obstruction, ulcers of the bowel, or inflammatory bowel or stomach disease
Contact your doctor or health care provider right away if any of these apply to you.
Before using neomycin:
Some medical conditions may interact with neomycin. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:
- if you are pregnant, planning to become pregnant, or are breast-feeding
- if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
- if you have allergies to medicines, foods, or other substances
- if you have diarrhea, a stomach infection, nerve damage, muscle weakness, Parkinson disease, kidney problems, or are dehydrated
Some MEDICINES MAY INTERACT with neomycin. Tell your health care provider if you are taking any other medicines, especially any of the following:
- Penicillin because it may decrease neomycin's effectiveness
- Cephalosporins (eg, cephalexin), cyclosporine, fludarabine, loop diuretics (eg, furosemide), methoxyflurane, or nitrosureas (eg, carmustine) because the risk of side effects such as kidney damage and hearing loss may be increased
- Anticoagulants (eg, warfarin), digoxin, loop diuretics (eg, furosemide), methotrexate, methoxyflurane, nondepolarizing muscle relaxants (eg, vecuronium), polypeptide antibiotics (eg, actinomycin), succinylcholine, or vancomycin because their actions and the risk of their side effects may be increased by neomycin
- Digoxin or methotrexate because their effectiveness may be decreased by neomycin
This may not be a complete list of all interactions that may occur. Ask your health care provider if neomycin may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.

- Long-term or repeated use of neomycin may cause a second infection. Tell your doctor if signs of a second infection occur. Your medicine may need to be changed to treat this.
- Lab tests, including hearing tests, may be performed while you use neomycin. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
