What is the pregnancy category for Atorvastatin?

Atorvastatin is classified as a Category X medication in pregnancy. This classification indicates that studies in animals or humans have demonstrated fetal abnormalities, and the risks involved in use of the drug in pregnant women clearly outweigh any possible benefits. Therefore, Atorvastatin is contraindicated throughout pregnancy, not just in the first trimester.

Category A medications are considered safe for use during pregnancy, showing no risk to the fetus in well-controlled studies. However, Atorvastatin does not fall into this category due to its significant associations with teratogenic effects. The contraindication in all trimesters further reinforces the serious risks posed by Atorvastatin during pregnancy, making it inappropriate for any stage of pregnancy.
