What weight loss medications are available in Australia?
Australia has 6 TGA-approved options: Wegovy (semaglutide), Mounjaro (tirzepatide), Ozempic (semaglutide, diabetes only), Duromine (phentermine), Contrave (naltrexone/bupropion), and Xenical (orlistat).
Do I need a prescription for weight loss medication?
Yes, except for low-dose orlistat (60mg) which is available over the counter. All other weight loss medications require a prescription from a doctor.
What BMI do I need for weight loss medication?
Generally BMI ≥30 (obesity) or BMI ≥27 with at least one weight-related health condition such as type 2 diabetes, high blood pressure, or sleep apnoea.
Can I get weight loss medication through telehealth?
Yes. Multiple telehealth providers in Australia prescribe weight loss medications via phone or video consultation with AHPRA-registered doctors.
Are weight loss medications covered by Medicare or PBS?
Currently, only Ozempic is PBS-subsidised (for diabetes, not weight loss). Wegovy PBS listing is pending for patients with obesity and cardiovascular disease.
What is the most effective weight loss medication?
Mounjaro (tirzepatide) shows the highest average weight loss in clinical trials (~21%), followed by Wegovy (15–17%). However, the best medication for you depends on your individual health circumstances.
Are compounded GLP-1 medications available?
No. Since October 2024, compounding pharmacies are banned from producing replicas of GLP-1 medications in Australia due to safety concerns.
How long do I need to take weight loss medication?
Most weight loss medications are intended for long-term use. Weight is typically regained after stopping, similar to how blood pressure returns when blood pressure medication is stopped.
