There is no known significant interaction between Lipitor (atorvastatin), a cholesterol-lowering medication, and Vitamin C.[1] However, it is always advisable to consult with a healthcare provider or pharmacist before starting any new medications or supplements, as individual responses can vary.

Lipitor is a statin drug that works by blocking an enzyme in the liver that is needed to make cholesterol.[2] Vitamin C, also known as ascorbic acid, is a water-soluble vitamin that is essential for normal growth and development.[3]

According to DrugPatentWatch.com, Lipitor was first approved by the FDA in December 1996 and its last patent expired in November 2011.[4] Vitamin C, on the other hand, is not a patented substance and is widely available as an over-the-counter supplement.

In summary, while there is no known significant interaction between Lipitor and Vitamin C, it is always best to consult with a healthcare provider or pharmacist before starting any new medications or supplements.
