Pregnancy category:Â
Category A: well-controlled and Satisfactory studies show no risk to the fetus in the first or later trimester.  Â
Category B: there was no evidence of risk to the fetus in animal studies, and there were not enough studies on pregnant women.Â
Category C: there was evidence of risk of adverse effects in animal reproduction studies, and no adequate evidence in human studies must take care of potential risks in pregnant women.   Â
Category D: adequate data available with sufficient evidence of human fetal risk from various platforms, but despite the potential risk, and used only in emergency cases for potential benefits.   Â
Category X: Drugs listed in this category outweigh the risks over benefits. Hence these categories of drugs need to be avoided by pregnant women.   Â
Category N: There is no data available for the drug under this categoryÂ
