No. You cannot advertise prescription weight-loss medication to the public in Australia. These are Schedule 4 medicines, so you cannot name the brand or the ingredient or point to a specific product in any public ad. There is a second reason too. Weight loss is treated as a restricted representation under the TGA code, so you cannot advertise treating weight or obesity with medication at all. You can still advertise a weight-management consultation. You can describe the service, who provides it, and how to book, as long as you never name a medicine or promise a result. The TGA has publicly warned that advertising these medicines to the public is unlawful.
Key takeaways
- Prescription weight-loss medicines are Schedule 4. They cannot be advertised to the public at all.
- Weight loss is also a restricted representation, so you cannot advertise treating weight with medication, even without naming a drug.
- You can advertise a weight-management consultation. Sell the appointment, not the medicine or the result.
- No before-and-after photos, no testimonials about results, no "lose X kilos" promises.
- The TGA is watching this category closely and has warned the public about unlawful ads.
Can you advertise weight-loss medication?
No. This is the most-asked question in healthcare marketing right now, and the answer is a clear no.
Weight-loss medicines have exploded in demand, and a lot of clinics raced to advertise them. Many of those ads break the law. There are two separate rules at work here, and a weight-loss ad usually breaks both at once. Understanding both is what keeps your page safe.
This post sits inside my wider guide to the TGA advertising code, and it builds on the foundational rule about advertising prescription medicines in Australia. If you only read one thing, read those two and this together.
Reason one: it is a prescription medicine
The current prescription weight-loss medicines are Schedule 4 medicines under the Poisons Standard. That puts them under the strictest line in the system. You cannot advertise a Schedule 4 medicine to the public.
The ban is wide. You cannot use the brand name. You cannot use the active ingredient. You cannot use a clear reference that points to one product, like "the weekly injection everyone is asking about". If a reader can tell which medicine you mean, you have named it in the eyes of the TGA.
This rule alone is enough to stop most of the weight-loss ads I see. The medicine simply cannot appear in your marketing.
Reason two: weight loss is a restricted representation
Here is the part most marketers have never heard of, and it catches even the careful ones.
The TGA code controls "restricted representations". These are references to serious diseases and conditions that you cannot use in public advertising without prior TGA approval. Weight loss and obesity sit in this group when they are linked to a medicine or a therapeutic claim.
So even if you never name a drug, you still cannot run an ad that promotes medical weight loss as an outcome. "Lose weight with our medical program" is a restricted representation. Most businesses do not hold TGA approval to make it, so the safe rule is simple. Do not advertise treating weight or obesity. Advertise the consultation where a doctor assesses a person's health.
The core idea: two rules stack here. The medicine cannot be named because it is Schedule 4. The outcome cannot be promised because weight loss is a restricted representation. Clear both, every time.
What can a weight clinic actually advertise?
Plenty. The rules limit your claims, not your right to market a real service. You can build a page that brings in genuine enquiries.
The safe pattern is to advertise the consultation, factually.
- The service. You can say your clinic offers weight-management consultations to discuss a person's health, who provides them, and what happens at the appointment.
- The process. You can explain that a doctor assesses each person and discusses suitable options, and that any treatment is decided by the doctor if it is clinically appropriate.
- The practice details. Location, hours, qualifications, pricing, and how to book.
What you describe is the assessment and the support. What you never describe is the medicine, the kilos someone might lose, or a before-and-after. Sell the appointment, not the outcome.
Say this, not that: five rewrites
Here are five common weight-loss lines that breach the rules, each with a compliant version. Every "say this" line is written to the full standard, so it works for the TGA and for the AHPRA advertising guidelines too.
| Not this (breach) | Say this (compliant) | Why it works |
|---|---|---|
| "Lose weight fast with [weight-loss medicine]. Book online today." | "Weight-management consultations with our doctors. Book an appointment to talk through your options." | Advertises the consultation. Names no medicine and promises no result. |
| "The injection that helped thousands drop the kilos." | "Our doctors assess your health and discuss options that may suit you." | No clear reference to a product and no outcome claim. |
| "Medical weight loss. Lose up to 15% of your body weight." | "A doctor-led weight-management service focused on your overall health." | No restricted representation and no promised figure. |
| "See Sarah's amazing transformation." (before-and-after photo) | "At your appointment, our team explains the service and answers your questions." | No before-and-after and no testimonial about results. |
| "Skip the GP. Same-day scripts delivered to your door." | "Appointments are usually available within a few days. Your doctor decides on any treatment if it is appropriate." | No urgency, no prescription-as-endpoint, no pharmacy channelling, and conventional care respected. |
The traps that get weight-loss ads pulled
Even clinics that avoid naming a medicine often trip on these. Each one is common, and each one is a breach.
- Before-and-after photos. They imply a guaranteed outcome and support a restricted representation. Out, always.
- Patient stories about results. A testimonial about losing weight is a clinical testimonial, which AHPRA bans for a regulated service.
- Numbers. "Lose up to X kilos" or "X% body weight" is an outcome promise. Cut every figure tied to a result.
- Urgency and inducements. "Limited spots", "this week only", or a discount on the program all add risk.
- Social media. A reel that names the medicine, or a comment from your clinic that does, is advertising. So is an influencer post you arranged.
The TGA has publicly warned about unlawful advertising of prescription weight-loss medicines, and it has acted on it. This is not a category to test the edges in.
Who is liable when it goes wrong?
The risk is real. The TGA can issue warnings and infringement notices, and it can take court action. Penalties for advertising offences are significant and can run into the millions for serious or repeated breaches.
The advertiser is liable, and the law reads "advertiser" broadly. That includes the agency and the copywriter who wrote the page, not only the clinic. If you write or sign off the copy, you carry the risk with the client. For a registered practitioner, the same breach can also become a complaint to AHPRA.
The fix is the same as always. Write to the rules from the first draft. A weight-management page can still rank and convert. It just sells the consultation, never the drug or the result.
