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.
Ask your prescriber
“I take Opioid analgesics. Is Foundayo (orforglipron) safe with it, and what should we monitor?”
