Lipitor is a brand name for atorvastatin, a medication used to lower cholesterol levels in the blood. According to the FDA, Lipitor falls under category X for pregnancy, which means that it has been shown to have negative effects on developing fetuses. The FDA advises that Lipitor should not be taken during pregnancy as it can cause birth defects and other health problems in the baby [2].

The effects of atorvastatin on a developing fetus are not fully understood. However, studies on animals have shown that atorvastatin can cause harm to developing fetuses, including birth defects, fetal death, and decreased growth. Additionally, the medication can pass through the placenta and enter the bloodstream of the fetus [3].

According to the University of Texas Southwestern Medical Center, pregnant women with familial hypercholesterolemia may be at an increased risk of complications during pregnancy and should discuss the risks and benefits of taking statins, including Lipitor, with their doctor. If a woman becomes pregnant while taking Lipitor, she should immediately stop taking the medication and consult her doctor [1].

In conclusion, Lipitor is not safe for use during pregnancy and can cause harm to developing fetuses. Pregnant women with familial hypercholesterolemia should discuss the risks and benefits of taking statins with their doctor, and if a woman becomes pregnant while taking Lipitor, she should stop taking the medication immediately and consult her doctor.
