Nitazoxanide 500mg is an antiparasitic and antiviral medication used to treat infections like diarrhea caused by Giardia lamblia and Cryptosporidium parvum. However, its safety for pregnant women has not been well established.

Currently, nitazoxanide 500mg is classified as a pregnancy category B drug by the FDA, meaning animal studies have not shown harm to the fetus, but there are no well-controlled studies in pregnant women. Therefore, it should only be used during pregnancy if the potential benefits outweigh the risks.

Pregnant women should consult their healthcare provider before taking Nitazoxanide 500mg to ensure it is safe for their specific condition.
