Are Wegovy and Ozempic the same drug?
Mostly, yes. Both labels list the generic name semaglutide, and both list Novo Nordisk as the maker (Ozempic, Wegovy).
What's different is what each one is approved for and the doses it comes in. The label is the official set of instructions the FDA approves for a medicine, so two products with the same medicine inside can have two labels.
What is Ozempic approved for?
- Blood sugar. Along with diet and exercise, to improve blood sugar in adults with type 2 diabetes.
- Heart. To lower the risk of major heart events (heart death, heart attack or stroke) in adults with type 2 diabetes and established heart disease.
- Kidneys. To lower the risk of kidney decline, end-stage kidney disease and heart death in adults with type 2 diabetes and chronic kidney disease.

What is Wegovy approved for?
Wegovy injection is approved, along with a reduced-calorie diet and more physical activity:
- Heart. To lower the risk of major heart events in adults with established heart disease and either obesity or overweight.
- Long-term weight management. In adults and in children 12 and older with obesity, and in adults with overweight who also have a weight-related condition.
- Liver. To treat noncirrhotic MASH (a liver disease, also called NASH) with moderate to advanced scarring, in adults. This one was approved under accelerated approval, so the FDA may need a confirmatory trial to keep it.
Wegovy tablets (a pill) share the Wegovy label. They're approved for heart risk reduction and long-term weight management in adults. Source: Wegovy label, section 1.
How are the doses different?
Each label was written from its own trials, at its own doses, so the steps are different. Both start at 0.25 mg once a week and go up slowly, which the labels say is 'to reduce the risk of gastrointestinal adverse reactions.'
| Ozempic | Wegovy injection | |
|---|---|---|
| Start | 0.25 mg once weekly for 4 weeks | 0.25 mg once weekly for 4 weeks |
| Next steps | 0.5 mg, then 1 mg or 2 mg if more blood sugar control is needed | 0.5 mg, 1 mg, then 1.7 mg, each for 4 weeks |
| Maintenance | 0.5 mg, 1 mg or 2 mg | 1.7 mg or 2.4 mg |
| Top of the label | 2 mg once weekly | 7.2 mg once weekly, a label option for adults' weight reduction after at least 4 weeks on 2.4 mg |
The Ozempic label says: 'The maximum recommended dosage is 2 mg once weekly.' Your prescriber decides your dose, and the steps on a label aren't a plan for you.
Do they work the same way?
Yes. Your gut makes a hormone called GLP-1. The labels say semaglutide is 'a GLP-1 analogue with 94% sequence homology to human GLP-1,' so it's a close copy with a few changes.
Picture a key and a lock. The medicine is the key. The lock is a receptor on the outside of a cell. When the key turns, the cell gets a message. Semaglutide fits the same lock in both products.
It lasts a week because it holds on to albumin, a protein that travels in your blood. The Ozempic label calls this 'the principal mechanism of protraction.' It also resists being broken down by an enzyme called DPP-4. The half-life is about 1 week for both: the labels say it's in your body for about 5 weeks after the last Ozempic dose, and about 5 to 7 weeks after the last Wegovy 2.4 mg or 7.2 mg injection or 25 mg tablet (section 12.3 of each label).
Do they have the same side effects?
Both labels list the same most common ones: nausea, vomiting, diarrhea, constipation and stomach pain. They also share serious warnings, like pancreatitis, gallbladder problems, low blood sugar and dehydration that can lead to kidney problems.
Don't compare rates from one label with the other. They come from different trials, in different people, at different doses.
Can you take Wegovy and Ozempic together?
No. Don't use them together, or with any other GLP-1 medicine.
“Concomitant use of WEGOVY (semaglutide) tablets or WEGOVY (semaglutide) injection with other semaglutide-containing products or with any other GLP-1 receptor agonist is not recommended.”
Keep a list of your medicines and show it to your prescriber and pharmacist.
Is there a pill version?
Yes. Wegovy tablets are on the Wegovy label (the maintenance dose is 25 mg once daily). Ozempic tablets share a label with Rybelsus, for adults with type 2 diabetes (Rybelsus label, section 1). Pill doses aren't a mg-for-mg swap for the shot, so a switch is a prescriber decision.
