Wegovy vs Ozempic: both are once-weekly injections of the same drug, semaglutide, from Novo Nordisk. Ozempic is approved for type 2 diabetes at doses up to 2 mg, while Wegovy is approved for weight management and heart-risk reduction at 2.4 mg (up to 7.2 mg for some adults).[1][2] The higher Wegovy doses produce more weight loss: about 15% of body weight in its main trial.[4]

Are Wegovy and Ozempic the same drug?
Yes. Both pens contain semaglutide, a GLP-1 receptor agonist with a half-life of about a week.[1][2] The differences are the doses each pen delivers, the conditions FDA approved each brand for, and therefore how insurers treat them. Neither label allows them to be used together: Wegovy’s label says not to combine it with other semaglutide products or any other GLP-1 drug.[2]
Doses compared
Both start at 0.25 mg once a week and step up every 4 weeks.[1][2]
| Step | Ozempic | Wegovy |
|---|---|---|
| Weeks 1–4 | 0.25 mg | 0.25 mg |
| Weeks 5–8 | 0.5 mg | 0.5 mg |
| Next steps | 1 mg, then 2 mg if needed | 1 mg, 1.7 mg, then 2.4 mg |
| Maximum | 2 mg[1] | 7.2 mg for adults who tolerate 2.4 mg for 4+ weeks[2] |
The Wegovy pill follows its own schedule, from 1.5 mg daily up to 25 mg.[2] Your prescriber sets the dose. Our semaglutide dosage chart has more detail.
Weight loss: Wegovy vs Ozempic
Because Ozempic is a diabetes drug, its trials measured blood sugar first. Wegovy’s trials measured weight.
| Trial | Dose | Who | Weight change |
|---|---|---|---|
| STEP 1 | 2.4 mg (Wegovy) | Obesity, no diabetes | −14.9% at 68 weeks vs −2.4% placebo[4] |
| STEP UP | 7.2 mg (Wegovy) | Obesity, no diabetes | −18.7% at 72 weeks[7] |
| STEP 2 | 2.4 mg (Wegovy) | Type 2 diabetes | −9.6% at 68 weeks vs −3.4% placebo[5] |
| SUSTAIN FORTE | 2 mg (Ozempic) | Type 2 diabetes | −6.4 kg at 40 weeks[6] |
| SUSTAIN FORTE | 1 mg (Ozempic) | Type 2 diabetes | −5.6 kg at 40 weeks[6] |
People with type 2 diabetes lost less weight in STEP 2 than people without diabetes did in STEP 1, a pattern seen with other GLP-1 drugs too.[4][5] Ozempic 2 mg also lowered HbA1c by 2.1 to 2.2 points in SUSTAIN FORTE.[6]
Can you use Ozempic for weight loss?
Ozempic is not approved for weight loss, so prescribing it to someone without type 2 diabetes is off-label. It does cause weight loss, because it is the same drug, but its pens stop at 2 mg. Wegovy goes to 2.4 mg and, since March 2026, to 7.2 mg for adults who need more, and those higher doses produced more weight loss in trials.[2][7] Insurers that cover Ozempic usually do so only for diabetes, so using it for weight loss can lead to denied claims.
Switching from Ozempic to Wegovy
Switching is common when someone’s goal or diagnosis changes. Neither label contains a conversion table, but because both brands use the same 0.25, 0.5 and 1 mg steps, a prescriber can usually continue from a comparable dose rather than starting over.[1][2] The Wegovy label advises restarting the escalation at a lower dose if two or more weekly doses in a row are missed, to limit stomach side effects.[2] Never take both at the same time.
The pill versions
Both brands now have tablets, but they are different products. Ozempic tablets (1.5, 4 and 9 mg) share a label with Rybelsus and are for type 2 diabetes.[3] The Wegovy pill is a 25 mg daily tablet for weight management and heart-risk reduction.[2] All semaglutide tablets must be taken on an empty stomach with a small sip of water, then a 30-minute wait before eating.[2][3] Read more in Rybelsus vs Ozempic and oral vs injectable semaglutide.
Heart, kidney and liver benefits
- Wegovy (SELECT): in 17,604 adults with heart disease and overweight but no diabetes, semaglutide 2.4 mg lowered heart attack, stroke or cardiovascular death from 8.0% to 6.5%.[8]
- Ozempic (SUSTAIN-6): in people with type 2 diabetes at high heart risk, those events fell from 8.9% to 6.6%.[9]
- Ozempic (FLOW): in type 2 diabetes with chronic kidney disease, semaglutide lowered major kidney events by 24%.[10]
- Wegovy (MASH): approved under accelerated approval for a form of fatty liver disease with moderate to advanced scarring.[2]
Side effects
The side effects are the same because the drug is the same: mainly nausea, diarrhea, vomiting and constipation, which are more common while the dose is going up.[1][2] In STEP 2, stomach side effects affected 63.5% on 2.4 mg, 57.5% on 1 mg and 34.3% on placebo.[5] Both carry a boxed warning about thyroid C-cell tumors seen in rodents and should not be used with a personal or family history of medullary thyroid cancer or MEN 2.[1][2]
Insurance coverage and cost
- Ozempic is usually covered as a diabetes drug, and plans often require a type 2 diabetes diagnosis.[1] See Ozempic cost with insurance.
- Wegovy coverage depends on whether your plan covers weight-loss drugs. Coverage for heart-risk reduction or MASH may be handled differently from weight loss.
- Medicare: Part D plans cover GLP-1s for type 2 diabetes, MASH and heart-risk reduction. From July 1, 2026 to December 31, 2027, the Medicare GLP-1 Bridge offers Wegovy (and certain other GLP-1s) for weight management at $50 a month to people who meet BMI criteria.[11]
- Self-pay: through NovoCare, both cost $349 a month at most doses in October 2026, with a $199 introductory price for the first two fills of the starting doses through December 31, 2026. Ozempic 2 mg is $499 and Wegovy 7.2 mg is $399.[12][13] Commercial savings cards can lower copays to as little as $25.[12][13]
Prices checked October 2026. They change often; confirm with NovoCare or your plan. See Wegovy cost without insurance for more.
Which one should you use?
- Type 2 diabetes, with or without kidney disease: Ozempic is the labeled choice.
- Obesity or overweight without diabetes: Wegovy is the labeled choice and offers higher doses.
- Heart disease with excess weight: Wegovy has the SELECT data and label.[8]
Using Ozempic for weight loss without diabetes is off-label. To compare semaglutide with its main rival, read semaglutide vs tirzepatide.
