Lipitor, the brand name for atorvastatin, is a medication used to lower cholesterol levels in the body [1]. According to the National Health Service (NHS), pregnant women should not take Lipitor because it can harm the fetus [2]. The American Pregnancy Association also advises against the use of Lipitor during pregnancy because it may cause birth defects and harm the developing baby [3].

While there is no conclusive evidence that Lipitor causes birth defects, studies in animals have shown that high doses of atorvastatin can cause fetal harm. The NHS recommends that women who are pregnant or planning to become pregnant should not take Lipitor, and should talk to their doctor about alternative medications if they need to lower their cholesterol levels [2].

In conclusion, Lipitor is not safe for pregnant women, and they should not take it without consulting their doctor. Women who are pregnant or planning to become pregnant should talk to their doctor about alternative medications for lowering cholesterol levels [2][3].
