Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the blood. When taking Lipitor, it is generally recommended to avoid consuming grapefruit juice as it can interfere with the way the body metabolizes the medication, potentially leading to increased levels of atorvastatin in the bloodstream. This can increase the risk of side effects associated with the drug. Other beverages, such as orange juice or apple juice, are not known to have significant interactions with Lipitor. However, it is always advisable to consult with a healthcare provider or pharmacist to get personalized advice on how to take Lipitor safely with specific beverages or foods [3].
