Lipitor (atorvastatin) is a medication used to lower cholesterol levels in the blood. According to the sources provided, there is no specific time frame that a person should wait to eat after taking Lipitor. However, it is recommended to take Lipitor at the same time every day and with or without food [2][3]. This is because food does not affect the absorption of Lipitor in the body [2]. It is important to follow the instructions provided by the prescribing doctor or pharmacist regarding the proper use of Lipitor [3]. Additionally, it is important to avoid consuming grapefruit or grapefruit juice while taking Lipitor as it can increase the risk of side effects [3].
