What is Metronidazole?

Metronidazole is commonly used as an anti-diarrheal medication that treat inflammation of the large intestine. It is also effective against certain protozoal and bacterial infections such as Giardia, Trichomonas and Balantidium coli. It is effective against only anaerobic pathogens, but is safe to use along with many other antibiotics for mixed infections.

Metronidazole is able to treat central nervous system infections that most other drugs cannot treat by penetrating the blood-brain barrier. It is also particularly effective against infections of the bone and teeth. Metronidazole requires a prescription from your veterinarian, and is sold by the tablet.
