Lipitor is a medication that contains atorvastatin, which is a type of statin used to lower cholesterol levels in the blood. The safety of taking Lipitor during pregnancy is not well established, and there is a risk of harm to the developing fetus. According to the National Health Service (NHS) [2], women who are pregnant or planning to become pregnant should not take Lipitor or any other statin medication. The American Pregnancy Association also advises against the use of atorvastatin during pregnancy [3].

The FDA has classified Lipitor as a pregnancy category X drug, which means that it is known to cause fetal harm and should not be used during pregnancy [1]. Animal studies have shown that atorvastatin can cause birth defects and fetal death when given to pregnant animals [2]. There have been reports of congenital anomalies in infants whose mothers took atorvastatin during pregnancy [3].

If a woman becomes pregnant while taking Lipitor, she should stop taking the medication immediately and consult with her healthcare provider. In some cases, it may be necessary to continue taking a cholesterol-lowering medication during pregnancy, but this should only be done under close medical supervision [3].

In conclusion, Lipitor should not be taken during pregnancy as it can cause harm to the developing fetus. Women who are pregnant or planning to become pregnant should discuss alternative treatment options with their healthcare provider.
