What's the difference between Ozempic and Wegovy?
Both contain semaglutide, both come as injections, and both are often mentioned in the same breath. But they are not the same. Here's what you need to know.
They contain the same active ingredient
Both Ozempic and Wegovy contain semaglutide — a GLP-1 receptor agonist that mimics a hormone involved in appetite regulation. They work the same way: slowing digestion, reducing hunger signals, and helping you feel full for longer.
But they're licensed for different purposes
Ozempic is licensed for the management of type 2 diabetes. It is not licensed as a weight-management product, although weight change can occur.
Wegovy is licensed specifically for weight management in adults with obesity. It uses higher doses — up to 2.4 mg per week — and clinical trials were conducted specifically with weight loss as the primary outcome. The results were more significant than those seen with Ozempic at its licensed dose.
What about Mounjaro?
Mounjaro (tirzepatide) is a different medication — it acts on GIP and GLP-1 receptors rather than GLP-1 alone. It has licensed uses for type 2 diabetes and weight management, but NHS access depends on the indication, individual eligibility, and the current primary-care or specialist pathway.
Which one can I get on the NHS?
If you have type 2 diabetes, your GP may prescribe Ozempic (or similar semaglutide products) if you meet NHS criteria for diabetic management.
If you are seeking medication for weight management, the available route may be primary care or a specialist service. It changes over time and varies locally. Ask the practice to check the current NHS pathway rather than requesting an off-label diabetes product.
Why do people ask for Ozempic for weight loss?
Media coverage often refers to Ozempic as a weight loss drug — partly because it became well known before Wegovy was widely available, and partly because some private clinics have been prescribing it off-label for weight management. This has caused supply shortages that have affected patients who rely on it for diabetes treatment.
If you are seeking weight-management support, ask for a clinical review of all appropriate options rather than a specific brand.
