Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels in the blood. According to the sources provided, there is not enough information available about the effects of atorvastatin on pregnancy to determine its safety.

The first source, Drug Patent Watch [1], provides information about the drug's patent status, but does not mention anything about its safety during pregnancy.

The second source, NHS [2], states that atorvastatin should not be taken during pregnancy unless it is absolutely necessary. This is because studies on animals have shown that atorvastatin can cause harm to the fetus. However, there is not enough information available on humans to determine its safety during pregnancy. If a woman becomes pregnant while taking atorvastatin, she should contact her doctor immediately.

The third source, American Pregnancy [3], also states that there is not enough information available to determine the safety of atorvastatin during pregnancy. However, it notes that high cholesterol levels can also pose a risk to both the mother and the baby, so it is important to work with a doctor to manage cholesterol levels during pregnancy.

In summary, there is not enough information available to determine the safety of atorvastatin (Lipitor) during pregnancy. Women who are pregnant or planning to become pregnant should consult with their doctor about the risks and benefits of taking this medication. It is important to manage cholesterol levels during pregnancy, but this should be done under the guidance of a healthcare professional.
