Lipitor is a medication used to treat high cholesterol levels, and it works by reducing the production of cholesterol in the liver [1]. According to Verywell Health, moderate alcohol consumption may not have a significant effect on the effectiveness of Lipitor, but excessive alcohol consumption can increase the risk of liver damage and interfere with the medication's ability to lower cholesterol levels [2]. Sutter Health suggests that people with high cholesterol levels should limit their alcohol intake to one drink per day for women and two drinks per day for men [3]. However, it is always best to consult with a healthcare provider before consuming alcohol while taking Lipitor or any other medication.
