Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels in the blood. While there are no specific juices to avoid when taking Lipitor, it is important to be aware of the potential interactions between grapefruit juice and statins, including atorvastatin. Grapefruit juice can increase the level of atorvastatin in the blood, leading to a higher risk of side effects [2]. Therefore, it is recommended to avoid consuming grapefruit juice while taking atorvastatin [3]. Other juices do not have the same effect on atorvastatin and are generally safe to consume. However, it is always important to consult with a healthcare provider before making any changes to your diet or medication regimen [1].
