Skim milk does not directly interfere with the effectiveness of Lipitor (atorvastatin), a medication used to treat high cholesterol levels. However, consuming dairy products with Lipitor might decrease the drug's absorption in the body [1]. This is because dairy products, including skim milk, contain calcium, which can bind to atorvastatin in the digestive system and prevent its absorption [2].

Nonetheless, this interaction is not expected to significantly affect the overall efficacy of Lipitor, as the body usually absorbs only a small percentage of the drug [3]. It is still recommended to maintain a consistent time interval between taking Lipitor and consuming dairy products, as instructed by a healthcare professional [4].

In summary, while skim milk does not directly interfere with Lipitor's effectiveness, it may affect the drug's absorption in the body. However, this interaction is not expected to significantly impact the drug's overall efficacy.
