Lactation:
Excreted into human milk is known
Pregnancy Categories:
Category A: Satisfactory and well-controlled studies show no risk to the fetus in the first or later trimester.
Category B: No evidence shown of risk to the fetus found in animal reproduction studies, and there are not enough studies on pregnant women
Category C: Adverse effects on the fetus found with evidence in animal reproduction studies and no adequate evidence for a result in humans must take care of potential risks in pregnant women
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.
Category X: Drugs listed in this category outweigh the risks over benefits. Hence these categories of drugs need to be avoided by pregnant women.
Category N: There is no data available for the drug under this category
