Lipitor is a brand name for atorvastatin, a medication used to lower cholesterol levels in the blood [1]. According to GoodRx, patients taking Lipitor or other statins should avoid consuming grapefruit or grapefruit juice, as it can increase the risk of side effects [2]. Grapefruit contains compounds that can interfere with the metabolism of statins, leading to higher levels of the medication in the bloodstream, which can increase the risk of side effects such as muscle pain, liver damage, and kidney failure [3]. It is recommended to wait at least 24 hours after taking Lipitor before consuming grapefruit or grapefruit juice [2]. However, it is always best to consult with a healthcare provider before making any changes to medication or diet.
