Lipitor is a medication used to lower cholesterol levels in the blood. According to the FDA, Lipitor falls under the pregnancy category X, which means that it is contraindicated during pregnancy as it may cause fetal harm when administered to pregnant women [3]. Lipitor is known to cross the placenta and may cause developmental abnormalities in the fetus, including skeletal malformations, decreased fetal weight, and increased fetal and neonatal mortality [2].

Therefore, it is highly recommended that women who are pregnant or planning to become pregnant should not take Lipitor or any other medication that contains atorvastatin. If a woman becomes pregnant while taking Lipitor, she should immediately stop taking the medication and contact her healthcare provider for further guidance.

It is also important to note that Lipitor can pass into breast milk and may harm a nursing baby. Women who are breastfeeding should not take Lipitor without consulting their healthcare provider.

In conclusion, Lipitor is contraindicated during pregnancy and should be avoided by women who are pregnant or planning to become pregnant. Women who are breastfeeding should also avoid taking Lipitor without consulting their healthcare provider.
