What happens when you drink alcohol and take metformin?

Drinking alcohol while taking metformin can increase the risk of developing lactic acidosis, a rare but serious condition characterized by the buildup of lactic acid in the body. Alcohol can also interfere with blood sugar levels, potentially leading to hypoglycemia or hyperglycemia. It's important to consume alcohol in moderation and consult a healthcare professional for personalized advice regarding alcohol consumption while on metformin.
