neomycin oral 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. 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.
Tell your doctor immediately if you notice 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.
Careful monitoring by your doctor will reduce the risk of these side effects. Monitoring may include hearing, kidney, and urine tests.
Avoid other medications that may increase your risk for these serious side effects if taken together with neomycin. See also Drug Interactions section.
neomycin oral 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). Unnecessary use or misuse of any antibiotic can lead to its decreased effectiveness.How to use neomycin oral

To decrease the risk of infection after intestinal surgery, this medication is usually taken for 3 or 4 doses the day before surgery, or as directed by your doctor. Carefully follow your doctor's directions for any diet restrictions and using this medication or other products before surgery.
For treating hepatic encephalopathy, this medication is usually taken four times a day for 5 to 6 days, or as directed by your doctor.
