Is There Another Name for Wegovy — and Does the Difference Matter?

Semaglutide: the ingredient behind all the names

Semaglutide is a GLP-1 receptor agonist, it mimics a gut hormone that signals fullness and slows how quickly food leaves the stomach. Novo Nordisk developed it and brought it to market under more than one brand because the medicine was originally studied for blood-sugar control in type 2 diabetes, and later trialled at higher doses specifically for weight management.

The Wegovy brand represents the weight-management formulations: the 2.4mg weekly injection (and now the newer 7.2mg dose approved in early 2026) and, as of June 2026, an oral tablet reaching a 25mg maintenance dose. If your prescription says semaglutide for weight loss, Wegovy is the brand your pharmacist will reach for. The NHS medicines page for semaglutide sets out the different products clearly and is worth bookmarking if you want a plain-English overview from a source you can trust.

A common misconception is that Ozempic is simply a cheaper version of Wegovy. It isn't. Ozempic contains semaglutide at doses used for diabetes (up to 2mg), is not licensed for weight management in the UK, and prescribing it off-label for weight loss sits outside normal NHS and most private clinical practice. The doses and the clinical indication are different. The brand name on the pack reflects that.

Ozempic, Rybelsus and why the licence question is the deciding one

Ozempic is a weekly semaglutide injection, and Rybelsus is an oral semaglutide tablet, both licensed in the UK for type 2 diabetes. They are not interchangeable with Wegovy for weight management purposes, legally or clinically. The MHRA licenses each medicine for a specific use, and that licence is what allows a prescriber to write a legal prescription for it. A prescriber offering you Ozempic or Rybelsus for weight loss would be working outside the licensed indication.

This distinction matters when you're reading about these medicines online, because much of the content (particularly from the US) uses the names interchangeably. In the UK, the comparison between Wegovy and Ozempic comes down to a straightforward regulatory fact: one is licensed for weight loss here, the other isn't.

If a seller is offering you Ozempic for weight loss, that is worth questioning. It may signal a prescriber working outside guidance, or (at the more dangerous end) a counterfeit supply chain. The MHRA has warned repeatedly about fake pens sold under recognisable brand names, and Ozempic's name recognition makes it a frequent target. Report anything suspicious through the MHRA's Yellow Card service.

What about Zepbound, Mounjaro and tirzepatide?

Tirzepatide is a different medicine entirely, a dual GIP and GLP-1 receptor agonist made by Eli Lilly. In the UK it's sold as Mounjaro. Zepbound is the US brand name for tirzepatide and does not exist as a UK product. If you've seen Zepbound mentioned on a UK website with UK pricing, that is a red flag worth noting.

Mounjaro and Wegovy are both licensed in the UK for weight management, but they work on different receptors and have different trial profiles. For adults trying to decide between them, the clinical picture (including your health history, your BMI and any other conditions) is what shapes the choice. A prescriber, not a brand name, makes that call. If the cost side of that decision is relevant to you, our treatment options page sets out the context honestly.

Wegovy tablets: the newest name to know

Since 11 June 2026 the MHRA has approved a third Wegovy formulation: an oral tablet. It's still semaglutide, still made by Novo Nordisk, still for weight management, but taken once daily on an empty stomach, no injection involved. The tablet escalates from 1.5mg to a 25mg maintenance dose, with at least a month at each level before moving up.

This matters for the "another name" question because some people searching for oral semaglutide for weight loss are being pointed toward Rybelsus, which is the wrong product. Rybelsus (3mg, 7mg, 14mg tablets) is licensed for type 2 diabetes, and if you are trying to understand another name for Wegovy it helps to know that Rybelsus is not it. They happen to share an active ingredient; everything else about them is distinct. Age eligibility for Wegovy in any form applies to adults only, if age is relevant to your situation, our guide on age limits for Wegovy covers the specifics.

Speak to our prescribers if you want a clinical view on which formulation of semaglutide, if any, fits your circumstances. If you are still uncertain after reading this page, our guide covering what's another name for Wegovy walks through the question in more detail.
