Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels and reduce the risk of heart attack and stroke [1]. Garlic is a commonly used herb that has been suggested to have potential health benefits, including lowering cholesterol levels [2].

There is limited information available on the potential interaction between garlic and Lipitor. However, a study published in the Journal of Clinical Pharmacy and Therapeutics found that garlic supplements did not significantly affect the effectiveness of atorvastatin in reducing cholesterol levels [3].

It is important to note that while garlic supplements may not affect the effectiveness of Lipitor, there may be other potential interactions with other medications. The New York Times reports that garlic supplements may interact with blood-thinning medications, such as warfarin, and increase the risk of bleeding [4]. Therefore, it is important to consult with a healthcare provider before taking garlic supplements, especially if taking other medications.

In conclusion, there is limited information available on the potential interaction between garlic and Lipitor. However, a study suggests that garlic supplements do not significantly affect the effectiveness of atorvastatin in reducing cholesterol levels. Nonetheless, it is important to consult with a healthcare provider before taking garlic supplements, especially if taking other medications.
