According to Drugs.com [2], there are no known interactions between atorvastatin (the generic name for Lipitor) and probiotics. However, it is always recommended to consult with a healthcare provider before taking any new medication or supplement.

A study published in the Journal of Clinical Pharmacy and Therapeutics [3] suggests that taking probiotics may actually have a positive effect on patients taking statins, such as atorvastatin. The study found that probiotics can help reduce the gastrointestinal side effects that some patients experience when taking statins.

DrugPatentWatch [1] provides information on the patent status of Lipitor, but does not provide any information on potential interactions with probiotics.

Overall, while there are no known interactions between atorvastatin and probiotics, it is always best to consult with a healthcare provider before taking any new medication or supplement.
