Can I drink alcohol on GLP-1?
Medically reviewed
GLP-1s slow gastric emptying, which prolongs alcohol's contact with the stomach and increases nausea risk. They also amplify the subjective effects of alcohol — many users notice intoxication and hangovers at much lower volumes than before treatment (NIAAA).
Practical guidance from clinical sources: skip alcohol for 24–48 hours after each dose, stay well-hydrated, avoid mixing with high-fat meals, and watch for hypoglycemia risk if you're also on insulin or sulfonylureas.
