Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels in the blood [1]. According to Express Scripts, there are no known interactions between probiotics and Lipitor [2]. However, it is important to note that this does not mean that there are no potential side effects or interactions.

A study published in the Journal of Clinical Pharmacy and Therapeutics found that some probiotics may interact with certain medications, including those used to lower cholesterol levels [3]. The study suggests that the potential for interactions may depend on the specific strain of probiotic and the medication being taken.

It is always important to consult with a healthcare provider before combining any medications or supplements, including probiotics and Lipitor. A healthcare provider can provide personalized advice based on an individual's specific health needs and medical history.

In conclusion, while there are no known interactions between probiotics and Lipitor, it is important to exercise caution and consult with a healthcare provider before combining any medications or supplements.
