According to the available information, there is limited data on the risks of Lipitor (atorvastatin) in breastfed infants. The manufacturer, Pfizer, states that it is not known whether atorvastatin is excreted in human milk [1]. However, a study published in the Journal of Clinical Psychiatry found that atorvastatin was present in the breast milk of a woman taking the medication [2].

The FDA states that it is not known whether Lipitor is excreted in human milk and that caution should be exercised when Lipitor is administered to a nursing woman [3]. The American Academy of Pediatrics classifies atorvastatin as a drug for which the effect on the nursing infant is unknown/possibly of concern [4].

It is important to note that Lipitor is a cholesterol-lowering medication and that breastfeeding is the best source of nutrition for most infants. Therefore, the potential risks of Lipitor to a breastfed infant should be weighed against the benefits of breastfeeding.

In conclusion, based on the available information, there is limited data on the risks of Lipitor in breastfed infants and caution should be exercised when administering Lipitor to a nursing woman.
