Lipitor (atorvastatin) is a medication used to lower cholesterol levels in the blood. According to the sources provided, Lipitor can be taken with or without food, and at any time of the day. However, it is recommended to take it at the same time every day to maintain a consistent level of the drug in the body [2, 3].

It is important to note that some foods may affect the absorption of Lipitor. Grapefruit and grapefruit juice, for example, should be avoided as they can increase the level of the drug in the blood and increase the risk of side effects [2]. Additionally, high-fat meals may decrease the absorption of the drug, so it is recommended to avoid consuming large amounts of fatty foods when taking Lipitor [3].

It is important to follow the instructions of the prescribing healthcare provider or the label on the medication. If there are any concerns or questions about how to take Lipitor, it is recommended to consult with a healthcare professional [2, 3].
