A plain-English awareness guide to medicines like semaglutide and tirzepatide — what they are, how cost and the PBS work in general, the risks of "copycat" products, and what to ask your GP.
GLP-1 receptor agonists are a class of prescription medicines used in Australia for type 2 diabetes and, separately, for weight management. You may have heard them referred to by brand names. They are Schedule 4 (prescription-only) medicines, so they can only be supplied on a valid prescription from an Australian-registered prescriber. This page explains the system around them — cost, access and safety — so you can have an informed conversation with your GP. It does not tell you whether to take one.
💡 Looking for the specifics? If you want to see the actual products available in Australia (Ozempic, Mounjaro, Wegovy, Trulicity) compared side-by-side — TGA indication, PBS status, cost — see the GLP-1 medicines in Australia guide.
What you pay depends heavily on why the medicine is prescribed:
Check current PBS listings and criteria at pbs.gov.au. Your GP and pharmacist can tell you what applies to your situation and what it will actually cost you.
The Therapeutic Goods Administration (TGA) has warned the public about compounded and unapproved "semaglutide-like" products sold online and by some clinics. These are not the same as TGA-approved medicines:
The safest path is a genuine, TGA-approved product dispensed by an Australian pharmacy against a valid prescription. Read the TGA's consumer information at tga.gov.au.
Supply of some of these medicines has been limited at times, which can affect availability and prescribing. Shortages and their expected resolution dates change frequently.
Check the current status on the TGA Medicine Shortage Reports Database via tga.gov.au, and ask your pharmacist about local availability.
In September 2026, Eli Lilly Australia launched LillyDirect, an online platform for prescribed Lilly medicines. Mounjaro (tirzepatide) is the first medicine on it.
The RACGP, the Pharmacy Guild of Australia and the Pharmaceutical Society of Australia have raised concerns about the model, including fewer opportunities for face-to-face checks and for a pharmacist to see a person’s full medicines list. Lilly says an Australian pharmacist reviews and dispenses every prescription and is available to advise.

If you're wondering whether one of these medicines could be relevant to you, a GP visit is the right next step. Questions you might bring:
Your GP knows your full history and circumstances — their advice always takes priority over general information like this.
