There is no indication that Lipitor (atorvastatin) affects milk production. Lipitor is a medication used to lower cholesterol levels in the blood and prevent cardiovascular disease [1]. According to the drug label approved by the U.S. Food and Drug Administration (FDA), there is no information regarding the effects of Lipitor on lactation or milk production [3]. Additionally, a review of literature published in the National Library of Medicine found no evidence that atorvastatin affects lactation or breast milk production [2].

It is important to note that Lipitor is contraindicated in pregnant and breastfeeding women as it may cause harm to the developing fetus or infant [3]. Women who are pregnant or breastfeeding should consult their healthcare provider before taking Lipitor or any other medication.
