Common questions readers ask
- Can you drink alcohol on Wegovy?
- No hard contraindication, but alcohol tolerance often drops sharply on GLP-1. Many patients also report reduced desire for alcohol — likely a secondary effect of GLP-1 on the brain reward system. Full evidence-graded answer
- Can I take GLP-1 while pregnant?
- No. All FDA-approved GLP-1s carry a pregnancy contraindication. Stop GLP-1 at least 2 months before planned conception due to its long half-life. Full evidence-graded answer
- Is it safe to take GLP-1 long-term?
- Liraglutide has 15+ years of post-marketing data (Victoza approved 2010). Semaglutide has 8+ years (Ozempic approved 2017). No new class-wide safety signals have emerged in extended follow-up. Chronic use is the FDA-approved indication for both T2D and obesity. Full evidence-graded answer
- What happens if I miss a weekly GLP-1 dose?
- If within 5 days: take the missed dose as soon as you remember, then resume the regular schedule. More than 5 days late: skip it and inject your next scheduled dose. Never double up. Full evidence-graded answer
- Can GLP-1 cause thyroid cancer?
- The boxed warning is based on rodent studies showing medullary thyroid carcinoma (MTC) in mice and rats. No human cases have been attributed to GLP-1 use despite 10+ years post-approval surveillance. Full evidence-graded answer
