Lipitor is a prescription medication used to lower cholesterol levels in the blood. It contains atorvastatin, which belongs to a group of drugs called statins [2]. According to Drug Patent Watch, there are no known drug interactions between Lipitor and any herbs [1]. However, it is important to note that this does not necessarily mean that it is safe to take Lipitor with any herb.

MedlinePlus recommends avoiding grapefruit and grapefruit juice while taking Lipitor because they can increase the level of the medication in the blood and increase the risk of side effects [2]. Additionally, the NHS advises caution when taking herbal supplements with Lipitor because some herbs may interact with the medication and affect its effectiveness or increase the risk of side effects [3].

Therefore, it is recommended to speak with a healthcare provider before taking any herbal supplements while on Lipitor. They can provide personalized advice and guidance on which herbs may be safe to take and which should be avoided [2][3].
