Lipitor (atorvastatin) is a medication used to lower cholesterol levels in the body. There is no evidence to suggest that Lipitor interacts with dairy products. However, it is important to note that certain foods, including dairy products, can affect the absorption of Lipitor in the body. According to the US Pharmacist [2], consuming grapefruit juice while taking Lipitor can increase the risk of side effects. Therefore, it is recommended to avoid consuming grapefruit juice while taking Lipitor.

Additionally, the absorption of Lipitor can be affected by the timing of meals. The medication should be taken at the same time every day, with or without food. However, high-fat meals can decrease the absorption of Lipitor, so it is recommended to avoid consuming high-fat meals when taking the medication [3].

In conclusion, there is no evidence to suggest that Lipitor interacts with dairy products. However, it is important to be mindful of the timing of meals and to avoid consuming grapefruit juice while taking Lipitor. As always, it is recommended to consult with a healthcare provider before making any changes to your medication or diet.
