Lipitor is a brand name for the drug atorvastatin, which is a type of statin used to lower cholesterol levels in the body [1]. According to the American Pregnancy Association, the use of atorvastatin during pregnancy is not recommended as it may harm the fetus [3]. The drug is classified as a pregnancy category X, which means that it has been shown to have harmful effects on fetal development when used during pregnancy [3].

The use of statins during pregnancy is not recommended, especially during the first trimester when fetal development is at its most critical stage [2]. According to a blog post by UT Southwestern Medical Center, the use of statins during pregnancy has been associated with an increased risk of birth defects, such as heart and lung abnormalities, as well as developmental delays [2].

It is important for women who are planning to become pregnant or are already pregnant to discuss their medication use with their healthcare provider to ensure the safety of their unborn child. In cases where a woman is taking atorvastatin for a medical condition, alternative medications may be prescribed that are safer for use during pregnancy [3].

In conclusion, the use of Lipitor or atorvastatin during pregnancy is not recommended as it may have harmful effects on fetal development. Women who are pregnant or planning to become pregnant should discuss their medication use with their healthcare provider to ensure the safety of their unborn child [2][3].
