Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels in the body [1]. Probiotics are live microorganisms that provide health benefits when consumed in adequate amounts [3].

There is limited information available on the potential interactions between Lipitor and probiotics. However, a study published in the International Journal of Clinical Pharmacology and Therapeutics suggests that probiotics may enhance the effectiveness of atorvastatin [3]. The study found that probiotics increased the bioavailability of atorvastatin, which could lead to a higher concentration of the drug in the body. This could potentially increase the risk of side effects associated with Lipitor, such as muscle pain and liver damage [1].

Additionally, the Express Scripts blog warns that some probiotics may interact with medications, including Lipitor, and reduce their effectiveness. It is recommended to talk to a healthcare provider before taking probiotics with any medication [2].

In conclusion, while there is some evidence to suggest that probiotics may enhance the effectiveness of Lipitor, there is also a potential for increased risk of side effects. It is important to talk to a healthcare provider before taking probiotics with Lipitor or any other medication [1][2][3].
