Lipitor is a prescription medication used to treat high cholesterol levels in the blood. It contains atorvastatin as the active ingredient [1]. According to the National Health Service (NHS), Lipitor is not recommended during pregnancy unless it is considered essential by a doctor. The NHS advises that women who are pregnant or planning to become pregnant should discuss their medication with their doctor or pharmacist before taking it. This is because Lipitor may harm the developing fetus [2].

Similarly, the American Pregnancy Association advises against taking Lipitor during pregnancy. They explain that atorvastatin belongs to a group of drugs called statins, which can cause birth defects and other problems in the fetus. They also warn that taking Lipitor during pregnancy can cause harm to the developing baby's brain and kidneys [3].

In conclusion, Lipitor is not considered safe to take during pregnancy, as it may cause harm to the developing fetus. Women who are pregnant or planning to become pregnant should consult their doctor or pharmacist before taking Lipitor or any other medication [2][3].
