Uses and warnings
BOXED WARNING: "Metronidazole has been shown to be carcinogenic in mice and rats" in long-term studies, and unnecessary use of the drug should be avoided. Contraindicated with known hypersensitivity to metronidazole or other nitroimidazole derivatives, in the first trimester of pregnancy for trichomoniasis, and with concurrent or recent (within 2 weeks) disulfiram use or alcohol/propylene-glycol-containing products due to disulfiram-like reactions. Also contraindicated in patients with Cockayne syndrome due to reports of severe hepatotoxicity/acute liver failure. Other warnings cover CNS effects (seizures, peripheral and optic neuropathy, encephalopathy) and severe cutaneous adverse reactions (SJS, TEN, DRESS).
Metronidazole tablets treat "trichomoniasis" (symptomatic and asymptomatic, including in male partners), "amebiasis" (intestinal disease and liver abscess), and serious infections caused by susceptible anaerobic bacteria involving the intra-abdominal cavity, skin and skin structure, gynecologic tract, central nervous system, lower respiratory tract, bone and joint, and endocarditis. The label stresses it should be used "only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria."
