Lipitor is a medication used to lower cholesterol levels in the blood. While taking Lipitor, it is important to be mindful of certain fruits that may interact with the medication. Grapefruit is one such fruit that should be avoided when taking Lipitor [3]. This is because grapefruit contains compounds that can interfere with the liver's ability to metabolize the medication, leading to an increased risk of side effects [3]. Other citrus fruits, such as oranges and limes, do not have the same effect as grapefruit and can be safely consumed while taking Lipitor [2]. However, it is always a good idea to consult with a healthcare provider or pharmacist before consuming any new foods while taking medication [2]. Additionally, it is important to note that Lipitor has many other drug interactions, so it is crucial to inform healthcare providers of all medications, supplements, and foods being consumed [1].
