Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels in the body [1]. According to the NHS, atorvastatin can interact with some herbal supplements, which can affect its effectiveness or cause side effects [2]. Therefore, it is essential to consult a healthcare professional before combining Lipitor with any herbal supplements.

The Mayo Clinic advises that some herbal supplements can interact with prescription medications, including Lipitor. For example, St. John's wort, ginkgo, and garlic can affect the liver's ability to break down Lipitor, leading to increased levels of the drug in the body, which can increase the risk of side effects [3]. Additionally, some herbal supplements, such as red yeast rice, contain compounds that are similar to the active ingredient in Lipitor, which can lead to an increased risk of side effects when taken together [3].

In conclusion, Lipitor can interact with some herbal supplements, which can affect its effectiveness or cause side effects. Therefore, it is essential to consult a healthcare professional before combining Lipitor with any herbal supplements [2][3].
