Lipitor is a medication used to lower cholesterol levels in the body. It contains the active ingredient atorvastatin, which belongs to a class of drugs called HMG-CoA reductase inhibitors. According to the American Pregnancy Association [2], there is not enough data to determine whether Lipitor is safe for use during pregnancy. Atorvastatin has been shown to cause harm to unborn babies in animal studies, and it is not recommended for use during pregnancy unless the potential benefits outweigh the risks. Women who are pregnant or planning to become pregnant should discuss the risks and benefits of using Lipitor with their healthcare provider [2]. Lipitor is classified as a Pregnancy Category X drug, which means that it is contraindicated in pregnancy because it can cause fetal harm [1]. It is important for women who are taking Lipitor to use effective contraception to prevent pregnancy while taking the medication [3]. In conclusion, based on the provided sources, Lipitor is not safe for unborn babies and should not be used during pregnancy unless the potential benefits outweigh the risks.
