Match the product to the purpose.
Semaglutide (Ozempic, Wegovy, Rybelsus) is made to act like a hormone released by the gut after a meal. A hormone carries signals inside the body. This medicine helps you feel full and helps the body manage blood sugar.
The U.S. agency responsible for drug approvals is FDA, short for Food and Drug Administration.
The approval check dated September 26, 2026 lists Wegovy, a semaglutide brand, for weight management.
For Ozempic, the September 26, 2026 approval record concerned type 2 diabetes in adults; that illness affects blood sugar.
Weight loss was not one of those approved uses.
A prescriber can use an approved drug for a purpose outside its approved uses. For example, Ozempic may be prescribed for weight loss even though FDA has not approved it for that purpose.
Read the result with its setting attached.
STEP 1 was a semaglutide study. Nobody in it had diabetes. Adults qualified either because they had obesity or because they had overweight and another health problem linked to their weight.
At 68 weeks, average weight loss was 14.9% with semaglutide and 2.4% with a dummy injection.
Both groups had lifestyle support and regular trial visits; the drug’s maker funded the study.
A dummy treatment helps researchers compare what happened with and without the study medicine. The result belongs to this trial, not to every product advertised with the same ingredient name.
Leave room for the downsides.
Feeling sick, vomiting, diarrhea and constipation were common in the Wegovy injection trials.
A boxed warning is the label’s most prominent alert; semaglutide’s concerns thyroid tumors seen in rats and mice. Whether those tumors occur in humans because of semaglutide remains unknown.
Medullary thyroid cancer is one rare kind of thyroid cancer. Semaglutide is ruled out by the label if that cancer occurred in you or your family.
Another condition listed is MEN 2. This rare illness runs in families, and the label rules out semaglutide for people who have it.
If you or a relative had thyroid cancer, ask the prescriber to check which kind it was. Ask them to check your medical records if the name MEN 2 is unfamiliar. You do not have to work out those diagnoses yourself.
Ask the prescriber to explain which warnings in the label fit your history, and what would make another option a better fit.
A pharmacy-made preparation is a separate question
