Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the blood. It works by blocking the enzyme responsible for producing cholesterol in the liver [1]. According to the NHS, it is generally safe to take atorvastatin with most other medications and herbal supplements. However, there are some exceptions. St. John's Wort, for example, can reduce the effectiveness of atorvastatin and increase the risk of side effects [2]. The Mayo Clinic advises caution when taking herbal supplements with any medication, including atorvastatin. They recommend speaking with a healthcare provider before taking any herbal supplements, as they can interact with medications and cause unwanted side effects [3].
