Lipitor is a medication used to lower cholesterol levels in the blood. It contains atorvastatin, a type of drug known as a statin. According to the American Pregnancy Association [3], there is no known safe level of statin use during pregnancy. Statins can cause fetal harm and birth defects when administered during pregnancy. The use of Lipitor is contraindicated in pregnancy as it can cause harm to the developing fetus [3].

According to UT Southwestern Medical Center [2], there is limited information on the safety of statins during pregnancy. However, studies in animals have shown that statins can cause fetal harm and even death. There is also a theoretical risk of fetal harm in humans. Pregnant women who are taking Lipitor should consult with their healthcare provider immediately and discontinue the medication if they become pregnant.

Drug Patent Watch [1] indicates that Lipitor is classified as a pregnancy category X drug, which means that it should not be used during pregnancy. Lipitor can cause fetal harm and is known to cause birth defects. Women who are pregnant or planning to become pregnant should not take Lipitor.

In conclusion, the use of Lipitor during pregnancy can be harmful to the developing fetus. Pregnant women should avoid taking Lipitor and consult with their healthcare provider if they are taking the medication and become pregnant. It is important to discuss all medication use with a healthcare provider before and during pregnancy to ensure the health and safety of both the mother and the developing fetus.
