Understanding treatment
What drug approval tells you.
Ask about the named product and the reason for using it. A medicine’s approval does not answer every question about your own care.
To begin
Approval belongs to a product
Semaglutide and tirzepatide are medicine ingredients used for blood sugar or weight. As of September 2026, Ozempic (semaglutide) and Mounjaro (tirzepatide) are approved to control blood sugar in people with type 2 diabetes.
Wegovy (semaglutide) and Zepbound (tirzepatide) are approved for weight loss alongside changes to eating and physical activity, as of September 2026. These are some of their approved uses; the full list depends on the exact product and form.
Ask the person prescribing it to name the exact product and explain its approved uses. The label is the medicine’s official information for prescribing it.
Look a little closer
A compounded product is a separate question
Compounded means made or changed for a patient rather than supplied as a finished drug-company product.
The US drug agency is the Food and Drug Administration, known here as FDA. For a compounded medicine, FDA has not assessed safety, quality, or whether it works before sale, as of September 2026.
Effectiveness means whether a treatment works. Ask what evidence supports this particular medicine and why a finished approved product would not meet the need.
Look a little closer
A drug number does not prove approval
A National Drug Code, or NDC, is a number used to identify a product in a drug list. An NDC number alone is not proof of FDA approval, as of September 2026.
Ask to see the FDA approval record for the exact medicine.
An approved medicine that is a version of a brand-name drug is called a generic.
Neither semaglutide nor tirzepatide has a generic version approved for the US market, as of September 2026.
Liraglutide is another medicine ingredient, used in Victoza for type 2 diabetes and Saxenda for weight loss. As of September 2026, some generic liraglutide medicines are approved for diabetes and some for weight loss. This is why a claim about generic medicines needs the exact medicine name and purpose.
Chapter recap
Keep this in mind.
Ask “Approved for what?” and “Which exact product?” Keep the answer with your cost notes.
