Based on the available information, there is no specific requirement or recommendation for food consumption with Lipitor (atorvastatin) [1][2]. It can be taken with or without food [1][2]. However, it is advised to take Lipitor in the evening, as this is when the body typically manufactures the most cholesterol [2].

It is important to note that certain foods can interact with Lipitor, such as grapefruit and grapefruit juice. These can increase the amount of Lipitor in your blood, which can increase your risk of serious side effects [3]. Therefore, it is generally recommended to avoid consuming grapefruit or grapefruit juice while taking Lipitor [3].

In all cases, it is crucial to follow the specific instructions provided by your healthcare provider or pharmacist [1][2].
