Yes, consuming grapefruit juice can exacerbate Lipitor's side effects. This occurs due to a chemical in grapefruit juice that interferes with the body's ability to metabolize Lipitor, leading to increased levels of the drug in the bloodstream [1]. This can enhance Lipitor's intended effects as well as its side effects. Common side effects of Lipitor include muscle pain, liver damage, kidney damage, and digestive problems [2]. It is recommended to avoid consuming grapefruit juice while taking Lipitor [1].
