Based on the information available, it is not explicitly stated that Lipitor users should avoid alcohol consumption due to potential liver risks. However, it is important to note that Lipitor, a medication used to treat high cholesterol, is metabolized in the liver [1].

The drug's active ingredient, atorvastatin, can increase levels of liver enzymes, which may indicate liver damage [1]. While moderate alcohol consumption typically does not cause liver damage, excessive drinking can lead to liver problems [2]. Therefore, it is plausible that combining Lipitor with heavy alcohol consumption could potentially increase the risk of liver damage.

It is always recommended that patients consult with their healthcare provider or pharmacist regarding potential interactions between their medications and alcohol consumption [1]. Healthcare professionals can provide personalized advice based on a patient's medical history, current medications, and alcohol consumption habits.

In summary, while there is no definitive evidence that Lipitor users should avoid alcohol due to potential liver risks, it is crucial for patients to consult with their healthcare providers about possible interactions between their medications and alcohol consumption.
