What is the pregnancy category of Metronidazole?

Metronidazole is classified as a pregnancy category B medication. This categorization means that studies in animals have not demonstrated a risk to the fetus, while there are no adequate and well-controlled studies in pregnant women. The benefits of using metronidazole during pregnancy may outweigh potential risks, particularly in cases where it is needed to treat certain infections that could pose a greater risk to both the mother and the fetus if left untreated.

This classification reflects a cautious approach, recognizing that while animal studies do not indicate fetal harm, the lack of extensive human clinical trials necessitates careful consideration when prescribing the medication to pregnant women. As a result, healthcare providers often evaluate the necessity of metronidazole on a case-by-case basis during pregnancy.
