Is Cagrilintide Legal in Australia? Prescription, Import and Supply Rules

Current status of cagrilintide in Australia

Cagrilintide is an investigational amylin analogue being studied for weight management, including in combination with semaglutide (often referred to in research as “CagriSema”). As at the time of publication, no cagrilintide product is registered on the ARTG for general supply in Australia.

Because it is not ARTG-registered, cagrilintide is considered an unapproved therapeutic good. That means routine pharmacy dispensing is not available, and any lawful use must occur under specific Therapeutic Goods Administration (TGA) mechanisms for unapproved medicines, such as:

• Special Access Scheme (SAS) Category B — case-by-case prescriber application and TGA notification/approval
• Authorised Prescriber Scheme — prescriber-level authorisation for defined patient groups
• Clinical trials — access governed by trial protocols and ethics approval

These pathways are designed for exceptional circumstances where a clinician judges that potential benefits may justify use despite the medicine not being registered. They are not blanket permissions to sell or promote the product to the public.

Does cagrilintide require a prescription?

Yes. Unapproved medicines accessed under SAS or the Authorised Prescriber Scheme require an Australian-registered prescriber to oversee care. There is no lawful over-the-counter route, and online self-purchase without a valid Australian prescription is not legal.

Many weight-loss injectables and peptide-like products are prescription-only under the Poisons Standard (Schedule 4). Even if cagrilintide is not explicitly named in the Schedule at this time, its use as a prescription-only, unapproved medicine remains the operative standard in practice.

If you see websites offering “no-script” cagrilintide inside Australia, that is a red flag for unlawful supply.

Can you personally import cagrilintide into Australia?

The TGA’s Personal Importation Scheme can under limited conditions allow individuals to import up to three months’ supply of some prescription medicines for personal use, but only if strict criteria are met. For cagrilintide, that generally means:

• You hold a valid prescription from an Australian-registered prescriber covering the imported quantity.
• The product is for personal use only, in original labelled packaging.
• You import no more than three months’ supply at a time and no more than 15 months’ supply in 12 months.
• No prohibited import controls apply and you truthfully declare the product at the border if required.

Even when individuals believe they meet these rules, shipments of unapproved injectable products are frequently scrutinised by Australian Border Force. Seizure or return-to-sender can occur if documentation is incomplete, the quantity exceeds limits, labelling is inadequate, sterility is uncertain, or import controls apply.

Compounding and pharmacy supply

In Australia, pharmacies may compound an unapproved medicine only when it is clinically justified for an individual patient, based on a valid prescription, and prepared in accordance with quality and sterility standards. However, many pharmacies will not compound high-risk sterile injectables or investigational agents such as cagrilintide. Supply is at the professional discretion of the prescriber and the compounding pharmacy, and must comply with TGA guidance.

Importantly, “copying” a brand medicine is prohibited where an equivalent registered product exists. For cagrilintide, there is no registered reference product, making any proposed compounding particularly sensitive to risk assessment, GMP-grade ingredient sourcing and clinical justification.

Advertising and “research peptide” claims

Australian law restricts advertising of prescription-only and unapproved medicines to the general public. Clinics and sellers are not permitted to promote cagrilintide by name to consumers. Beware of:

• Domestic or overseas sites selling “research-only” or “for lab use” vials to Australians
• Promotions guaranteeing delivery of unapproved injectables
• Web pages implying TGA approval when none exists

Such offers commonly breach therapeutic goods and advertising laws. They also raise safety concerns about sterility, identity and dosing.

Approved alternatives and related options

If your goal is medical weight management, discuss approved options and eligibility with your clinician. In Australia, GLP-1 or dual-agonist therapies such as semaglutide (Wegovy/Ozempic) and tirzepatide (Mounjaro) have defined indications and safety information. Access can still be subject to prescriber judgement, PBS status and supply constraints.

Final takeaway

Cagrilintide is not TGA-approved in Australia. Lawful access, if considered, runs through prescriber-led unapproved medicine pathways or clinical trials. Personal import is tightly constrained and risky if requirements are not met. Be cautious of online sellers making easy-access claims.

If your goal is weight management, speak with an Australian prescriber about approved options and whether any unapproved pathway is appropriate for your circumstances.
