Coumadin is classified as what type of pregnancy category?

Coumadin, also known as warfarin, is classified as a pregnancy category X medication. This classification indicates that there is substantial evidence of risk to the fetus based on human studies or substantial risk based on animal studies. The use of Coumadin during pregnancy is associated with congenital malformations and adverse pregnancy outcomes, particularly during the first trimester and the later stages of pregnancy. Therefore, it is contraindicated in pregnancy, as the risks significantly outweigh any potential benefits. Understanding this classification is crucial for healthcare providers when considering medication management for pregnant patients, ensuring they opt for safer alternatives that pose less risk to fetal development.
