Wegovy vs Ozempic: Same Ingredient, Different Approved Uses
Why sharing semaglutide does not make two products a like-for-like substitute.
Patients often ask whether Wegovy is simply Ozempic with another label. Both contain semaglutide, but a prescribing decision also depends on the product’s approved purpose, presentation and instructions.
Start with the indication
SAHPRA’s semaglutide guidance identifies Ozempic as a diabetes medicine rather than a locally registered weight-loss product. Wegovy has its own South African professional information for weight management. Ask your clinician which product information applies to the proposed treatment.
A pen is not a conversion chart
Products can differ in strengths and use instructions. Do not compare pen clicks, improvise a conversion or take both products together. If your pharmacy cannot supply a prescription, ask the prescriber and pharmacist to resolve the problem rather than buying a different pen yourself.
Bring the right information
At an appointment, explain whether your main concern is diabetes management, weight-related health risk or both. Bring current prescriptions and the actual packaging of any semaglutide already being used. A photograph of a label can support the conversation, but it does not replace a verified prescription record.
Discuss monitoring and continuity
Ask what outcome will be reviewed and when, including health measures relevant to your treatment. Also ask what to do about adverse effects or a gap in supply. Access rules and approvals outside South Africa should not be assumed to apply locally; a clinician should confirm the current local position.
Key Takeaways
- The active ingredient is only part of the comparison.
- Approved indications and product instructions differ.
- Never convert pen doses or combine brands yourself.
- Supply problems require advice from the prescriber or pharmacist.
