Lipitor is a prescription medication used to lower cholesterol levels in the body. Grapefruit juice can interact with Lipitor, causing an increase in the drug's concentration in the bloodstream and leading to potential side effects. As a result, it is generally recommended to avoid consuming grapefruit or grapefruit juice while taking Lipitor [2][3]. The same is true for other statins, such as Zocor [2]. The interaction between grapefruit and Lipitor is due to a compound in grapefruit that inhibits the body's ability to break down the drug, leading to higher levels of the drug in the bloodstream [3]. Therefore, it is important to follow the advice of your healthcare provider and avoid consuming grapefruit or grapefruit juice while taking Lipitor or other statins [2][3].
