Yes, metronidazole does pass through the placenta. It's classified as a category B drug by the FDA, indicating that animal studies have not shown a risk to the fetus, but there are no adequate and well-controlled studies in pregnant women. However, it's often used during pregnancy to treat bacterial infections under careful consideration by healthcare providers, especially in the second and third trimesters. Always consult with a healthcare provider for advice tailored to your specific situation.
