Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the body. While there is limited information available on the effects of Lipitor on breastfeeding, the drug is not recommended for use during breastfeeding. According to the FDA, Lipitor is excreted into human milk, and it is not known if the drug can harm a nursing infant. Therefore, women who are breastfeeding should consult with their healthcare provider before taking Lipitor [3].

The drug patent for Lipitor expired in 2011, which has led to the availability of generic versions of the medication [1]. However, it is important to note that the active ingredient in both the brand name and generic versions of Lipitor is atorvastatin. Therefore, the potential effects of Lipitor on breastfeeding would also apply to generic versions of the medication.

According to the National Center for Biotechnology Information, there is limited information available on the safety of atorvastatin during breastfeeding. However, the organization recommends that women who are breastfeeding should avoid using the medication unless the potential benefits outweigh the potential risks to the infant [2].

In conclusion, while there is limited information available on the effects of Lipitor on breastfeeding, the medication is not recommended for use during breastfeeding due to the potential risks to the nursing infant. Women who are considering taking Lipitor while breastfeeding should consult with their healthcare provider to determine the best course of action.
