The short answer

Aggressive bowel regimen is required. Consider non-opioid alternatives where clinically possible.

Avoid combiningTalk to your prescriber before combining

Why it matters

Additive delay of gastric and small-bowel transit. Risk of severe constipation, ileus, and (rarely) small-bowel obstruction.

What to do

Prophylactic bowel regimen (osmotic laxative + stimulant) from day one of GLP-1 if opioids are ongoing. Reconsider opioid taper or non-opioid pain control. Stop the GLP-1 immediately and seek care for abdominal pain that lasts beyond 24 hours.

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.

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.
