Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the blood [1]. However, there is limited information on whether or not Lipitor can affect breast milk production. According to the FDA, Lipitor is excreted into the milk of lactating rats, but it is not known if Lipitor is excreted into human milk [3].

The National Center for Biotechnology Information (NCBI) states that there is no data on the effects of atorvastatin on milk production or excretion into human milk [2]. However, it is recommended that women who are breastfeeding should not take Lipitor unless the benefits of the medication outweigh the potential risks to the infant [3].

It is important to consult with a healthcare provider before taking Lipitor while breastfeeding. The healthcare provider can evaluate the potential risks and benefits of the medication and determine the best course of treatment for the individual [3].

In conclusion, there is limited information on whether or not Lipitor can affect breast milk production. It is recommended that women who are breastfeeding should not take Lipitor unless the benefits of the medication outweigh the potential risks to the infant. It is important to consult with a healthcare provider before taking Lipitor while breastfeeding.
