Lipitor is a statin medication used to lower cholesterol levels in the body. However, consuming grapefruit or grapefruit juice while taking Lipitor can lead to potential dangers. Grapefruit contains a compound called furanocoumarins, which interferes with the body's ability to break down Lipitor, leading to higher levels of the medication in the bloodstream [2]. This can increase the risk of side effects, such as muscle pain, liver damage, and kidney failure [3]. In some cases, consuming grapefruit with Lipitor can also lead to a rare but serious condition called rhabdomyolysis, which causes muscle breakdown and can lead to kidney damage [1]. Therefore, it is important to avoid consuming grapefruit or grapefruit juice while taking Lipitor [2][3].
