Based on the information available, there is no clear consensus on whether Lipitor (atorvastatin) should be taken while breastfeeding. The limited data on this topic suggests that atorvastatin is present in human breast milk, but the potential effects on a nursing infant are not well-understood [1].

The manufacturer of Lipitor, Pfizer, states that it is not known whether atorvastatin is excreted in human milk and advises caution when prescribing the drug to nursing mothers [2]. Similarly, the National Library of Medicine's LactMed database notes that there is limited information on the use of atorvastatin during breastfeeding and recommends considering alternative medications with more data available [3].

It is important to note that the benefits of breastfeeding for both mother and infant are well-established, and in most cases, the potential risks of medication exposure through breast milk are low [4]. However, in situations where a medication is necessary and there are concerns about its safety during breastfeeding, a healthcare provider may recommend temporarily discontinuing breastfeeding or using an alternative medication with a more established safety profile.

In summary, while there is some evidence that atorvastatin is present in human breast milk, the potential effects on a nursing infant are not well-understood. Healthcare providers should consider the risks and benefits of using Lipitor during breastfeeding on a case-by-case basis.
