Can I drink grapefruit juice while taking Lipitor?
Yes, there is an interaction between Lipitor (atorvastatin) and grapefruit juice. According to the FDA, grapefruit and grapefruit juice should be avoided while taking Lipitor [1]. The active ingredient in grapefruit juice, furanocoumarin, inhibits an enzyme called CYP3A4, which is responsible for breaking down atorvastatin. When CYP3A4 is inhibited, the levels of atorvastatin in the body increase, which can lead to increased risk of side effects such as muscle damage (myopathy) and liver damage (elevated liver enzymes) [2].

In severe cases, grapefruit juice consumption can lead to more serious complications, including rhabdomyolysis (a condition in which muscle tissue breaks down) and acute kidney injury [3].
How can I avoid interactions between Lipitor and grapefruit juice?
