Lipitor is a medication used to lower cholesterol levels, while multivitamins are supplements that contain a variety of vitamins and minerals. According to the sources provided, there are no known interactions between Lipitor and multivitamins. However, it is important to note that some supplements may interact with statins, a class of drugs that includes Lipitor. ConsumerLab suggests avoiding supplements that contain large amounts of niacin or red yeast rice, as these may increase the risk of side effects when taken with statins. Additionally, Drugs.com notes that taking Lipitor with certain minerals, such as calcium, may decrease the absorption of the medication. It is always important to consult with a healthcare provider before starting any new medication or supplement regimen to ensure safety and effectiveness.
