Wegovy vs Ozempic: Key Differences Explained

Semaglutide has taken the world by storm as a leading weight loss and diabetes medication. In New Zealand, Wegovy and Ozempic are often mentioned in the same breath — and for good reason: they’re both based on the same active ingredient. But they’re not the same medication.

If you’ve been exploring medical weight loss options, this article will help you understand the key differences between Wegovy and Ozempic, and which might be right for you.

What Do Wegovy and Ozempic Have in Common?

Wegovy and Ozempic are both GLP-1 receptor agonists containing semaglutide, a medication that mimics a natural hormone involved in appetite and blood sugar regulation.

Originally developed to treat type 2 diabetes, semaglutide was later found to promote significant weight loss — leading to the creation of Wegovy.

Both medications:

• Are injectable and taken once a week

• Help reduce appetite and increase feelings of fullness

• Slow digestion and reduce food cravings

The Key Differences Between Wegovy and Ozempic

While they share the same active ingredient, Wegovy and Ozempic differ in key areas:

Feature	Wegovy	Ozempic
Purpose	Specifically approved for weight loss	Approved for type 2 diabetes management
Dosage Strength	Up to 2.4 mg per week	Up to 1.0 mg per week
Weight Loss Effect	Higher clinical weight loss outcomes	Weight loss is a secondary benefit
Availability in NZ	Available via select GPs and clinics	Not routinely available
Brand Messaging	Marketed for obesity treatment	Marketed for diabetes

In short, Wegovy is the version of semaglutide developed specifically for weight loss. It allows for higher doses that lead to more pronounced results.

Which One is Better for Weight Loss?

For weight loss alone, Wegovy tends to deliver better results due to its higher dosing. Clinical trials show Wegovy users may lose up to 15% of their body weight, especially when paired with professional support and lifestyle changes.

While some GPs may prescribe Ozempic off-label for weight management, it's not its intended use — and patients may not reach the same level of weight loss due to dosage limits.

What About Side Effects?

Because they’re both semaglutide-based, Wegovy and Ozempic share a similar side effect profile:

• Nausea or vomiting

• Constipation or diarrhoea

• Headaches or fatigue

• Appetite changes

Side effects typically ease over time, especially when dosing is increased gradually with GP guidance.

Can You Switch Between the Two?

Yes - but it really depends on a patient's medical history and the key indication for starting a GLP-1 medication. This should always be done with a qualified GP who can monitor your progress and adjust accordingly.
