Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels. Vitamin E is a fat-soluble vitamin that has antioxidant properties and is often used as a dietary supplement. While there is no known interaction between Lipitor and vitamin E, there are potential side effects of combining these two substances.

According to DrugPatentWatch [1], the most common side effects of Lipitor include headache, muscle pain, diarrhea, and constipation. These side effects are generally mild and go away on their own. However, in rare cases, Lipitor can cause serious side effects such as liver damage, muscle damage, and an increased risk of diabetes.

Vitamin E is generally considered safe when taken in recommended doses, but high doses can cause side effects such as nausea, diarrhea, and stomach cramps [3]. Additionally, vitamin E can increase the risk of bleeding, especially when taken in combination with blood-thinning medications like warfarin [3].

While there is no known interaction between Lipitor and vitamin E, it is important to talk to a healthcare provider before taking any new medications or supplements, especially if you have any underlying health conditions or are taking other medications. They can help you determine if the benefits of taking Lipitor and vitamin E outweigh the potential risks and side effects.

In conclusion, while there is no known interaction between Lipitor and vitamin E, both substances can cause potential side effects. It is important to talk to a healthcare provider before taking any new medications or supplements to determine if they are safe and appropriate for you.
