Lipitor is a medication used to lower cholesterol levels in the blood. According to the sources provided, there are certain juices that should be avoided while taking Lipitor. Grapefruit juice is the most commonly known juice that should be avoided while taking Lipitor. Grapefruit juice contains compounds that can interfere with the liver's ability to metabolize Lipitor, leading to increased levels of the medication in the blood. This can increase the risk of side effects [2].

In addition to grapefruit juice, other juices that should be avoided while taking Lipitor include pomegranate juice, apple juice, and orange juice. These juices contain compounds that can also interfere with the liver's ability to metabolize Lipitor, leading to increased levels of the medication in the blood [3].

It is important to note that while these juices should be avoided, it is still important to maintain a healthy diet while taking Lipitor. Eating a diet rich in fruits and vegetables can help to lower cholesterol levels and reduce the risk of heart disease. It is recommended to talk to a healthcare provider or a registered dietitian for personalized dietary recommendations [3].
