Lipitor is a medication used to treat high cholesterol levels and reduce the risk of heart disease. According to Drug Patent Watch [1], the active ingredient in Lipitor is atorvastatin calcium. It is a type of medication known as a statin, which works by blocking the production of cholesterol in the liver. Grapefruit juice can interact with some statins, including Lipitor, by increasing the amount of medication in the bloodstream, which can lead to an increased risk of side effects [2]. It is recommended to avoid consuming grapefruit juice when taking Lipitor [3]. However, there is no information available regarding the consumption of other types of juice with Lipitor. It is always advisable to consult with a healthcare provider before making any changes to medication or diet [2].
