Lipitor is a brand name for the drug atorvastatin, which is a medication used to lower cholesterol levels in the body. According to Drug Patent Watch [1], Lipitor is classified as a statin drug and is used to treat high cholesterol. It works by blocking an enzyme in the liver that produces cholesterol.

Herbal supplements are often used as a complementary therapy for various health conditions, including high cholesterol. However, it is important to be aware of any potential interactions between herbal supplements and Lipitor.

According to a study published in the Journal of Pharmacy Practice and Research [2], there are several herbal supplements that may interact with statin drugs, including Lipitor. These include St. John's wort, ginkgo biloba, and garlic supplements. St. John's wort may reduce the effectiveness of Lipitor by increasing the metabolism of the drug, while ginkgo biloba and garlic supplements may increase the risk of bleeding when taken with Lipitor.

ConsumerLab [3] also recommends avoiding the use of red yeast rice supplements when taking statin drugs, including Lipitor. Red yeast rice contains a compound called monacolin K, which is chemically identical to the active ingredient in the prescription statin drug lovastatin. Taking red yeast rice supplements with Lipitor may increase the risk of side effects, such as muscle pain and liver damage.

In summary, it is important to be cautious when taking herbal supplements with Lipitor. Some supplements may interact with the drug and increase the risk of side effects or reduce its effectiveness. Patients should always consult with their healthcare provider before taking any herbal supplements while on Lipitor or any other medication.
