Compounded Semaglutide: Is It Safe?
Pending medical review
Short answer: Compounded semaglutide is not FDA-approved, and the FDA does not check it for safety or quality before it is sold. The FDA has received hundreds of reports of side effects, some needing a hospital.
What is it?
It is semaglutide mixed by a pharmacy, not the brand Wegovy or Ozempic made by the drug company.
What the FDA has seen
- As of May 31, 2026, the FDA had 990 reports of side effects linked to compounded semaglutide, and more than 730 for compounded tirzepatide.
- Some people got hurt from wrong doses, like measuring the shot wrong. Some went to the hospital.
- The FDA says some sellers use "salt forms" (semaglutide sodium or acetate). These are different from the approved medicine.
- The FDA has found fake labels naming pharmacies that did not make the product.
Why reports may be missing
The FDA says many pharmacies are not required to report side effects, so the real number is likely higher.
What should I do?
Talk to your doctor. Only buy from state-licensed pharmacies. Report problems to FDA MedWatch.
