Metronidazole is used as an antibiotic to treat anaerobic bacterial infections. Anaerobic bacteria cannot live in the presence of oxygen. It is also used as an antiprotozoal to treat Giardia infections. Metronidazole is readily absorbed from the intestinal tract into the bloodstream.
Metronidazole is used as an antibiotic and as an antiprotozoal drug to treat Giardia infections that result in an infectious form of severe diarrhea. It is commonly used with other antibiotics to treat pleuropneumonia, peritonitis, abdominal abscesses, and other severe infections caused by aerobic and anaerobic bacteria. Veterinarians often prescribe it to prevent infection after colic or after abdominal surgery, when mixed bacterial infections are a risk.
Metronidazole is absorbed rectally and may be used with very sick animals when weight loss and appetite loss are problems.
