What ORNIDAZOLE is used for

Ornidazole contains the active ingredient ornidazole.

ornidazole is used to treat people who have certain types of the vaginal, urinary tract and intestinal infections, or some specific infections that are in the body. These infections may be caused by anaerobic bacteria (bacteria that do not use oxygen) or amoeba (single-celled parasites).

ornidazole is also used to guard against the possibility of these types of infections during surgery (prophylaxis).

ornidazole belongs to a group of medicines called antiprotozoals. These medicines work by targeting the bacteria or amoeba in your body and killing them.

Your doctor, however, may have prescribed ornidazole for another purpose.

Ask your doctor if you have any questions about why ornidazole has been prescribed for you.

This medicine is available only with a doctor?s prescription.
