Lipitor is a medication used to lower cholesterol levels in the blood. According to the sources provided, there is no specific time frame that one needs to wait after meals to take Lipitor. However, it is generally recommended to take the medication at the same time every day, with or without food [2,3]. It is important to follow the instructions provided by your healthcare provider or the medication label. Taking Lipitor with food may help to reduce stomach upset that can occur with the medication [2]. Additionally, it is important to avoid consuming grapefruit or grapefruit juice while taking Lipitor as it can increase the risk of side effects [3].
