Lipitor (atorvastatin) is a medication used to lower cholesterol levels in the blood. Garlic, on the other hand, is a natural food that has been claimed to have several health benefits, including reducing cholesterol levels.

There is limited information available on whether Lipitor interacts with garlic. However, according to a study published in the Journal of Pharmacy and Pharmacology, garlic supplements may reduce the effectiveness of atorvastatin by decreasing its absorption in the body [2]. The study found that taking garlic supplements with atorvastatin reduced the maximum concentration of the drug in the blood by 51%.

It is important to note that this study was conducted on a small sample size and further research is needed to confirm the findings. Additionally, the study only looked at the interaction between garlic supplements and atorvastatin, not garlic as a food.

Therefore, it is recommended that patients taking Lipitor should avoid taking garlic supplements without consulting their healthcare provider [3]. It is also advisable to inform the healthcare provider about any other medications or supplements being taken to avoid any potential interactions.
