Lipitor is a medication used to treat high cholesterol, while probiotics are live bacteria and yeasts that are beneficial to the digestive system. The combination of Lipitor and probiotics has not been extensively studied, so it is unclear whether there are any significant side effects when taking them together.

However, it is important to note that both Lipitor and probiotics can cause gastrointestinal side effects. Lipitor can cause nausea, diarrhea, and abdominal pain [1], while probiotics can cause bloating, gas, and stomach upset [3]. Therefore, taking both Lipitor and probiotics together may increase the risk of experiencing gastrointestinal side effects.

Additionally, some research suggests that probiotics may interact with certain medications by altering their absorption, metabolism, or elimination [2]. However, there is no evidence to suggest that probiotics interact with Lipitor specifically.

Overall, while there is no clear evidence of significant side effects when combining Lipitor and probiotics, it is important to speak with a healthcare provider before starting any new supplements or medications. They can provide personalized advice and monitor for any potential interactions or adverse effects.
