Lipitor, the brand name for atorvastatin, is a medication used to lower cholesterol levels in the blood. However, its use during pregnancy is not recommended as it may pose risks to the developing fetus [2]. According to a study, the use of statins, including atorvastatin, during pregnancy may increase the risk of congenital anomalies, preterm birth, and low birth weight [2]. Additionally, the use of atorvastatin during pregnancy may also affect the development of the fetal nervous system [2].

Pregnant women with familial hypercholesterolemia, a genetic condition that causes high levels of cholesterol, may need to take medication to control their cholesterol levels. However, the use of statins during pregnancy should be avoided, and alternative treatments should be considered [2]. In such cases, a specialist should be consulted to determine the appropriate course of treatment [2].

The NHS advises women who are pregnant or planning to become pregnant to avoid taking atorvastatin [3]. It is also not recommended for women who are breastfeeding, as atorvastatin may pass into breast milk and harm the nursing infant [3]. Women who are taking atorvastatin and are planning to become pregnant should discuss their options with their doctor [3].

In conclusion, the use of atorvastatin during pregnancy is not recommended as it may pose risks to the developing fetus. Pregnant women with familial hypercholesterolemia should consult with a specialist to determine the appropriate course of treatment. Women who are pregnant or planning to become pregnant should avoid taking atorvastatin, and those who are breastfeeding should also avoid it. It is important to discuss any concerns or questions with a healthcare provider [2][3].
