Lipitor is a brand name for atorvastatin, which is a medication used to lower cholesterol levels in the blood [1]. According to Verywell Health, drinking alcohol while taking Lipitor may increase the risk of liver damage and other side effects [2]. In addition, Health Harvard states that alcohol consumption can interfere with the effectiveness of statins like Lipitor, which may lead to an increased risk of heart disease and stroke [3]. Therefore, it is recommended that people taking Lipitor should avoid excessive alcohol consumption and consult their doctor before drinking alcohol while taking this medication.
