This medication is usually injected into a vein. However, this product comes in vials which may also be given by mouth to treat a severe intestinal condition known as Clostridium difficile-associated diarrhea. This condition can rarely occur after the use of antibiotics has allowed the growth of a certain kind 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. (See also How to Use section.)
This medication is usually given by injection into a vein, usually 1 or 2 times a day or as directed by your doctor. It should be injected slowly over 1 to 2 hours. The dosage is based on your medical condition, weight, kidney function, and response to treatment. (See also Side Effects.)

When taking this medication by mouth, mix each dose into at least 1 ounce (30 milliliters) of water before swallowing all of the mixture.
