DescriptionMetronidazole is a commonly used antibiotic, belonging to the nitroimidazole class of antibiotics.[L3754] It is frequently used to treat gastrointestinal infections as well as trichomoniasis and giardiasis, and amebiasis which are parasitic infections.[A181036,A18039] Metronidazole has been used as an antibiotic for several decades[L7429], with added antiparasitic properties that set it apart from many other antibacterial drugs, allowing it to treat a wide variety of infections. It is available in capsule form, tablet form, and topical form, and suppository preparations for the treatment of various infections.

Some may also be present in the bloodstream in cases of septicemia. Common infections treated by metronidazole are Bacteroides species infections, Clostridium infections, and Fusobacterium infections, as well as Peptococcus and Peptostreptococcus infections.[L3754] It is also used off-label in the treatment of Crohn's disease and rosacea, as a prophylactic agent after surgery[A181039], and in the treatment of Helicobacter pylori infection.[A181045] It has also been studied in the prevention of preterm births and to treat periodontal disease.[A1391,A181078]
