Lipitor is a medication used to lower cholesterol levels in the body [1]. Grapefruit juice can interact with Lipitor, causing the medication to stay in the body for a longer period of time, increasing the risk of side effects [2]. Therefore, it is recommended to avoid grapefruit juice while taking Lipitor [2][3]. Other types of juice, such as orange juice or apple juice, are safe to consume with Lipitor [3]. However, it is always recommended to consult with a healthcare provider or pharmacist before consuming any type of juice while taking Lipitor or any other medication [2].
