What is semaglutide, and what do I ask?

What do the names mean?

The Food and Drug Administration uses the short name FDA. This agency in the U.S. checks medicines for approval.

Semaglutide is the ingredient in Ozempic, Wegovy, and Rybelsus. These are brand names. FDA medicine approval records listed these brands in September 2026.

The Wegovy medicine information describes semaglutide as a modified version of a hormone from the gut. That hormone is a body signal involved in blood sugar and appetite.

Ask for the brand and form together, such as a tablet or injection.

Is Ozempic the same weight-care product as Wegovy?

In September 2026, Ozempic’s approved uses were for adults with type 2 diabetes, a disease involving high blood sugar. Its medicine information did not approve weight loss.

The Wegovy medicine information did include weight care. A care professional can lawfully prescribe an approved medicine for a use outside its FDA approval. That does not give Ozempic a weight-loss approval.

Ask what health need is being treated and which product matches that need.

What has a weight study shown?

In STEP 1, adults with obesity or overweight and a related condition, without diabetes, lost 14.9% on average over 68 weeks with semaglutide.

The placebo group lost 2.4%. Placebo means a comparison shot without the active medicine. Both groups received advice on eating and physical activity and attended regular visits.

Novo Nordisk funded the study. These averages leave room for widely different personal results.

What needs a careful conversation?

The Wegovy medicine information lists nausea, meaning a sick stomach, plus vomiting, diarrhea, and constipation among common side effects.

The thyroid, found in the neck, is a gland that makes hormones. Hormones are signals in the body.

Wegovy’s boxed warning is FDA’s strongest kind of medicine warning. The warning reports thyroid tumors found in mice and rats. It is unknown whether semaglutide causes the same tumors in people.

MEN 2 is a rare illness that a child can inherit from a parent. Its full name describes tumors in body parts that make hormones. If a relative has this diagnosis, bring the name to your visit. If you are unsure which illness a relative had, ask the care professional to help check the family history.

The medicine information rules out use if you or a relative has had medullary thyroid cancer, a rare cancer of that gland. Having MEN 2 also rules out use.

Is a pharmacy-made version a generic?

A generic has FDA approval of its own and is another version of a brand-name medicine.

No FDA-approved generic semaglutide was available on the U.S. market in September 2026, according to FDA records. A compounded version is a separate kind of product.
