According to Drugs.com [1], there are no known interactions between Lipitor (atorvastatin) and vitamin E. Lipitor is a medication used to lower cholesterol levels, while vitamin E is an antioxidant supplement that can help protect cells from damage. However, it is always important to consult with a healthcare professional before taking any new medications or supplements, as individual circumstances can affect how different substances interact in the body.

The Drug Patent Watch [2] website provides information on the patent status of Lipitor, but does not provide any information on drug interactions.

A study published in the Journal of Clinical Lipidology [3] found that vitamin E supplementation did not significantly affect the cholesterol-lowering effects of atorvastatin. However, the study did note that high doses of vitamin E (greater than 400 IU per day) have been associated with an increased risk of bleeding, particularly in individuals taking blood-thinning medications.

In conclusion, while there are no known interactions between Lipitor and vitamin E, it is always important to consult with a healthcare professional before taking any new medications or supplements, particularly if you are taking other medications or have underlying health conditions.
