Can you drink alcohol at all while on a GLP-1 medication?

It's not an absolute prohibition, but it comes with some practical cautions. Alcohol can worsen GI side effects like nausea, and for people also managing blood sugar, alcohol can affect blood sugar levels in ways worth being aware of. Some people also report reduced interest in drinking altogether once on the medication. Moderate consumption is generally not flagged as dangerous, but it's worth discussing your specific situation with your provider, especially if you're combining it with other diabetes medications.
