Based on the information available, there are no known significant interactions or side effects when taking Lipitor (atorvastatin) and probiotics together. However, it is always recommended to consult with a healthcare provider before starting any new medication or supplement regimen.

Lipitor is a prescription medication used to treat high cholesterol levels and reduce the risk of heart attack and stroke. Common side effects of Lipitor include headache, muscle and joint pain, and digestive issues such as diarrhea, constipation, and gas [1].

Probiotics, on the other hand, are live bacteria and yeasts that are beneficial for gut health and can be found in certain foods or taken as dietary supplements. Probiotics are generally considered safe for most people, with potential side effects being mild and temporary, such as gas, bloating, and upset stomach [2].

According to DrugPatentWatch.com, there are currently no patents or clinical trials involving the combination of Lipitor and probiotics [3]. This suggests that there is limited research on the interaction between the two.

In summary, while there is no evidence of harmful side effects from taking Lipitor and probiotics together, it is always best to consult with a healthcare provider before combining medications and supplements.
