Lipitor is a medication used to lower cholesterol levels in the body. While taking Lipitor, it is important to be aware of certain fruits that may interact with the medication. Grapefruit and grapefruit juice are the most commonly known fruits to avoid while taking Lipitor as they can increase the risk of side effects. Grapefruit contains a compound that can interfere with the liver's ability to metabolize Lipitor, leading to higher levels of the medication in the bloodstream [1][2]. Other citrus fruits, such as oranges and tangerines, may also have similar effects and should be consumed in moderation [3]. Additionally, it is recommended to avoid consuming large amounts of pomegranate or drinking pomegranate juice while taking Lipitor as it may increase the risk of side effects [3]. It is important to consult with a healthcare provider or pharmacist for more information on potential interactions between Lipitor and other foods or medications [2].
