Vancomycin is used to treat colitis (inflammation of the intestine caused by certain bacteria) that may occur after antibiotic treatment. Vancomycin is in a class of medications called glycopeptide antibiotics. It works by killling bacteria in the intestines. Vancomycin will not kill bacteria or treat infections in any other part of the body when taken by mouth. Antibiotics will not work for colds, flu, or other viral infections. Vancomycin comes as a capsule to take by mouth. It is usually taken 3-4 times a day for 7-10 days. To help you remember to take vancomycin, take it around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take vancomycin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Take vancomycin until you finish the prescription, even if you feel better. If you stop taking vancomycin too soon or miss doses, your infection may not be completely cured and bacteria may become resistant to antibiotics. Before taking vancomycin, •tell your doctor and pharmacist if you are allergic to vancomycin, or any other medications. •tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking. Be sure to mention amikacin (Amikin), amphotericin B (Fungizone), bacitracin, cisplatin (Platinol), colistin, gentamicin (Garamycin), kanamycin (Kantrex), polymyxin B, streptomycin, and tobramycin (Nebcin). •tell your doctor if you have or have ever had inflammatory bowel disease (swelling of the intestine that can cause painful cramps or diarrhea), including Crohn's disease (a condition in which the body attacks the lining of the digestive tract, causing pain, diarrhea, weight loss, and fever) and ulcerative colitis (a condition which causes swelling and sores in the lining of the colon [large intestine] and rectum); hearing loss; or kidney disease. •tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking Vancomycin, call your doctor.
