Lipitor is a medication used to treat high cholesterol levels in the blood, while probiotics are live microorganisms that can benefit human health when consumed in adequate amounts. According to the sources provided, there is no known interaction between Lipitor and probiotics, and combining the two is generally considered safe.

The first source, Drug Patent Watch [1], provides information on the patent status of Lipitor but does not offer any information on potential interactions with probiotics.

The second source, a study published in the Nutrition Journal [2], investigated the effect of probiotics on cholesterol levels in humans. The study found that probiotics could help lower LDL cholesterol levels, which is the "bad" cholesterol that can contribute to heart disease. However, the study did not report any adverse effects associated with combining probiotics and Lipitor.

The third source, a review article published in the Journal of Clinical Gastroenterology [3], discusses the safety of probiotics and their potential side effects. The article notes that probiotics are generally safe for healthy individuals, but some people may experience mild gastrointestinal symptoms such as bloating, gas, and diarrhea. However, the article does not mention any specific interactions between probiotics and Lipitor.

In summary, based on the sources provided, there is no evidence to suggest that combining Lipitor and probiotics is harmful. However, as with any medication or supplement, it is always best to consult with a healthcare provider before starting any new regimen.
