Lipitor is a brand name for the medication atorvastatin, which is used to treat high cholesterol levels in the blood. According to the NHS [2], it is generally safe to combine atorvastatin with most herbal remedies. However, some herbs may interact with atorvastatin and cause unwanted side effects. For example, St. John's Wort may reduce the effectiveness of atorvastatin and increase the risk of side effects such as muscle pain. It is recommended to consult a healthcare professional before taking any herbal remedies while on atorvastatin.

The Mayo Clinic [3] also recommends caution when combining herbal supplements with prescription medications, including atorvastatin. They advise that some herbal supplements may interact with prescription medications, altering their effectiveness or causing unwanted side effects. The Mayo Clinic recommends that patients should inform their healthcare provider of any herbal supplements they are taking before starting any new prescription medications.

Drug Patent Watch [1] provides information on the patent status of Lipitor. It is important to note that this source does not provide information on the safety of combining Lipitor with natural remedies.

In conclusion, while it is generally safe to combine atorvastatin (Lipitor) with most herbal remedies, some herbs may interact with atorvastatin and cause unwanted side effects. It is recommended to consult a healthcare professional before taking any herbal remedies while on atorvastatin. It is also important to inform healthcare providers of any herbal supplements being taken before starting any new prescription medications.
