Vancomycin is an antibiotic used to treat a severe intestinal condition known as Clostridium difficile-associated diarrhea. This condition usually occurs after the use of another antibiotic, which allows the growth of resistant bacteria in the intestines, leading to severe diarrhea. When vancomycin is given by mouth, it is not absorbed by the body but remains in the intestines, allowing it to stop the growth of the bacteria responsible for this form of colitis.
This antibiotic treats only bacterial infections of the intestines. It will not work for other bacterial infections or viral infections (e.g., common cold, flu). Unnecessary use or overuse of any antibiotic can lead to its decreased effectiveness.
Dosage is based on your medical condition and response to treatment.
Cholestyramine and colestipol can decrease vancomycin's effects when given at the same time. If you are taking either of these drugs, separate them from vancomycin by at least 3 to 4 hours. If you are unsure, ask your pharmacist about the best way to do this.
This antibiotic works best when the amount of medicine in your intestines is kept at a constant level. Therefore, take this drug at evenly spaced intervals.
Continue to take this medication until the full prescribed amount is finished, even if symptoms disappear after a few days. Stopping the medication too early may result in a return of the infection.
Tell your doctor if your condition persists after 7 days or worsens at any time.
