Lipitor is a brand name for the drug atorvastatin, which is a medication used to lower cholesterol levels in the blood. As of 2021, there are no dairy-free alternatives to Lipitor available on the market. Atorvastatin is not known to contain lactose, which is a sugar found in milk and other dairy products, and is often used as a filler in medications. However, it is important to note that some medications may contain lactose or other dairy derivatives, which can be problematic for individuals with lactose intolerance or dairy allergies [2]. Patients who are lactose intolerant or allergic to dairy should consult with their healthcare provider or pharmacist to determine if a medication is safe for them to take. The FDA recommends that patients who are lactose intolerant or allergic to dairy should always read the label and check with their healthcare provider or pharmacist before taking any medication [3].
