Ozempic vs Wegovy

Same medicine inside, but they're licensed for different things, go up to different doses and come in different pens.

[00] Short answer

  1. Ozempic and Wegovy both contain semaglutide, a GLP-1 receptor agonist, injected once a week1–2.
  2. Ozempic is approved for type 2 diabetes. It starts at 0.25 mg and goes up to a maximum of 2 mg a week1.
  3. Wegovy is approved for weight reduction and heart risk. It starts at 0.25 mg, the usual maintenance dose is 2.4 mg, and adults using it for weight can go up to 7.2 mg2.
  4. In the UK, the MHRA lists Ozempic as licensed for diabetes only and Wegovy for weight management only5.
  5. The pens aren't interchangeable. They hold different strengths, and neither label explains how to switch from one brand to the other1–2.

What's the difference between Ozempic and Wegovy?

The medicine is the same. Ozempic and Wegovy both contain semaglutide, made by Novo Nordisk1–2. What differs is the approval: Ozempic is a type 2 diabetes medicine with doses up to 2 mg a week, and Wegovy is a weight and heart-risk medicine with doses up to 2.4 mg, or 7.2 mg for weight loss in adults1–2.

The nausea figures come from different trials in different people (diabetes vs weight), so they can't be compared directly. Both labels say so.

Both carry the same boxed warning about thyroid C-cell tumors seen in rodents1–2. For side effects by dose, see the GLP-1 side effects guide.

Ozempic vs Wegovy doses: why does Wegovy go higher?

Wegovy goes higher because it was studied and approved at higher doses for weight. The US Ozempic label stops at 2 mg a week, while Wegovy's usual maintenance dose is 2.4 mg and adults using it for weight can step up to 7.2 mg after at least 4 weeks on 2.4 mg1–2.

  • Ozempic adds each step only "if additional glycemic control is needed", so many people stay on 0.5 mg or 1 mg1.
  • Wegovy steps up every 4 weeks on a fixed schedule. If a dose isn't tolerated, the label says to consider delaying the next step by 4 weeks2.
  • For weight in adults, the Wegovy maintenance dose is 1.7 mg or 2.4 mg (recommended). For heart risk it's 2.4 mg (recommended) or 1.7 mg. For MASH it's 2.4 mg2.
  • The UK Ozempic SmPC also says weekly doses above 2 mg are not recommended3.

The 7.2 mg dose has its own rules and trial results. See Wegovy 7.2 mg. The full week-by-week schedules for both brands are on the semaglutide dosage chart.

Are Ozempic and Wegovy pens the same?

No. In the US, Ozempic comes in multi-dose pens that each give 4 doses, plus single-dose syringes. Wegovy comes mostly as single-dose pens and syringes, plus a 4-dose FlexTouch pen that only gives 2.4 mg1–2.

How Ozempic and Wegovy are supplied in the US (prescribing information, section 3)
OzempicWegovy
Multi-dose pens2 mg/3 mL (0.25 mg and 0.5 mg doses), 4 mg/3 mL (four 1 mg doses), 8 mg/3 mL (four 2 mg doses)1FlexTouch 9.6 mg/3 mL, four 2.4 mg doses2
Single-dose pensNone0.25, 0.5, 1, 1.7, 2.4 mg, and 7.2 mg (Wegovy HD)2
Single-dose syringes0.25, 0.5 or 1 mg in 0.5 mL10.25 to 2.4 mg2

The strength of the liquid differs too. Ozempic's 2 mg/3 mL pen is 0.68 mg/mL, while the Wegovy FlexTouch is 3.2 mg/mL1–2. In the UK, a 0.25 mg Ozempic pen holds 1.34 mg/mL and a 0.25 mg Wegovy FlexTouch holds 0.68 mg/mL3–4. So the same dial setting or click count doesn't give the same dose across brands.

Ozempic vs Wegovy in the UK

In the UK, Ozempic is licensed only for type 2 diabetes in adults, and Wegovy for weight management, heart-risk reduction and MASH3–4. The MHRA's table lists Ozempic as "No" for weight loss and Wegovy as "No" for diabetes treatment5.

Note that the UK Wegovy missed-dose rule (5 days) differs from the US one (next dose more than 2 days away)2,4. The missed-dose guide covers both.

Can you switch between Ozempic and Wegovy?

Neither label gives a way to switch between Ozempic and Wegovy. The only switching rules on the US Wegovy label are between Wegovy injections and Wegovy tablets2. The MHRA says to get advice from a healthcare professional before switching, "including between brands containing the same type of GLP-1"5.

Because the doses, pens and approved uses differ, which dose you'd move to is your prescriber's call. Check with your prescriber or pharmacist before you change brand.

Questions

Is Ozempic the same as Wegovy?

Same medicine, different product. Both contain semaglutide. Ozempic is approved for type 2 diabetes with a maximum of 2 mg a week. Wegovy is approved for weight reduction and heart risk, usually at 2.4 mg a week, and up to 7.2 mg for weight in adults.

Is Ozempic approved for weight loss?

No. In the US, Ozempic is approved for type 2 diabetes and related heart and kidney risks. The semaglutide brand approved for weight is Wegovy. In the UK, the MHRA lists Ozempic as licensed for diabetes only.

What's the highest dose of Ozempic?

2 mg once a week. The US label reaches it after at least 4 weeks on 1 mg, and the UK SmPC says weekly doses above 2 mg are not recommended.

Is 2 mg of Ozempic the same as 2.4 mg of Wegovy?

No. They are different doses of the same medicine, and 2.4 mg is 0.4 mg more. Neither label gives a way to switch between the two brands, so ask your prescriber what dose applies to you.

Can I use an Ozempic pen to take my Wegovy dose?

Not without your prescriber's say-so. The pens hold different strengths, so the same setting doesn't give the same amount of semaglutide. The Wegovy label also says not to use it with other semaglutide products.

Does Wegovy cause more nausea than Ozempic?

Nausea was 44% on Wegovy 2.4 mg in the weight trials, and 15.8% to 20.3% on Ozempic 0.5 mg to 1 mg in the diabetes trials. Those trials used different doses in different people, and both labels say rates can't be compared directly.
