Pregnancy & Breastfeeding
Pregnancy Teratogenic effects Teratogenic effects: Pregnancy category B: There has been no experience to date with the use of metronidazole gel USP (topical), 0.75%, in pregnant patients. Metronidazole crosses the placental barrier and enters the fetal circulation rapidly. No fetotoxicity was observed after oral metronidazole in rats or mice. However, because animal reproduction studies are not always predictive of human response and since oral metronidazole has been shown to be a carcinogen in some rodents, this drug should be used during pregnancy only if clearly needed.
