Tirzepatide in Australia
Get tirzepatide prescribed lawfully in Australia by an AHPRA-registered doctor — either Mounjaro on a private script, or compounded tirzepatide under the TGA Special Access Scheme Category B. $99 initial telehealth consult, cold-chain dispense to your door.
AHPRA-registered doctors
Tirzepatide is prescribed only after a clinical review by a registered Australian medical practitioner bound by the Medical Board of Australia's standards.
Mounjaro or TGA SAS-B
Mounjaro is ARTG-registered and dispensed at any Australian pharmacy. Compounded tirzepatide is lawful under TGA SAS-B via a TGA-licensed Australian compounding pharmacy.
Cold-chain dispense
Pens and vials ship cold-chain Mon–Wed from an Australian pharmacy, arriving within 2–4 business days. No customs risk, no offshore vendors.
What is tirzepatide?
Tirzepatide is a once-weekly subcutaneous injection that activates two gut-hormone receptors at the same time — GIP (glucose-dependent insulinotropic polypeptide)and GLP-1 (glucagon-like peptide-1). Activating both pathways slows gastric emptying, increases satiety, and improves insulin sensitivity. It was originally developed for type 2 diabetes and is now widely used for medically supervised weight management.
In Australia tirzepatide is available as Mounjaro — the Eli Lilly branded product on the ARTG — and as compounded tirzepatide dispensed by a TGA-licensed Australian compounding pharmacy under TGA SAS-B. Both contain the same active molecule; they differ in regulatory pathway, dose flexibility, and price.
Typical clinical indications
- Type 2 diabetes (glycaemic control)
- BMI ≥30 — medically supervised weight management
- BMI ≥27 with weight-related comorbidity (T2D, hypertension, dyslipidaemia, OSA)
- Plateaued response on semaglutide where dual-receptor agonism is clinically justified
Administration & titration
Once-weekly subcutaneous injection (abdomen, thigh, or upper arm). Standard titration starts at 2.5 mg/week for 4 weeks, increasing in 2.5 mg steps every 4 weeks as tolerated, up to a maximum of 15 mg/week. Most patients find a clinically effective dose between 5 mg and 12.5 mg. Slower titration reduces gastrointestinal side effects.
Cautions and contraindications
Not prescribed in pregnancy or breastfeeding, with personal/family history of medullary thyroid carcinoma or MEN-2 syndrome, with prior pancreatitis, or with active gallbladder disease. Use caution with insulin or sulfonylureas (hypoglycaemia risk). Stop 1 week before elective surgery requiring general anaesthesia (gastric-emptying delay).

Do not import tirzepatide from overseas
Importing tirzepatide yourself from offshore "research chemical" vendors is illegal under the Customs Act, gives no guarantee of sterility or potency, and leaves you with no Australian doctor if something goes wrong. The lawful path is AHPRA-registered doctor → ARTG or TGA SAS-B → Australian pharmacy. See why staying local matters.
Tirzepatide Australia — FAQs
- Is tirzepatide legal in Australia?
- Yes. Tirzepatide is legal in Australia. The branded product Mounjaro is registered on the ARTG and dispensed at any Australian pharmacy with a private script. Compounded tirzepatide is also lawful when prescribed by an AHPRA-registered Australian doctor under the TGA Special Access Scheme Category B (SAS-B) and dispensed by a TGA-licensed Australian compounding pharmacy. Importing tirzepatide yourself from overseas remains illegal under the Customs Act.
- How much does tirzepatide cost in Australia per month?
- As a 2026 guide: Mounjaro (the branded Eli Lilly product) is approximately AUD $400–$650 per month on a private script, depending on dose. Compounded tirzepatide from a TGA-licensed Australian pharmacy is typically AUD $300–$550 per month depending on titration. Neither is currently PBS-subsidised for weight management.
- How do I get a tirzepatide prescription in Australia?
- Book a telehealth consult with an AHPRA-registered Australian doctor (PeptideDoctorAU initial consult is $99). The doctor reviews your eligibility, BMI, comorbidities, and any baseline pathology, then writes either a private Mounjaro script or a TGA SAS-B notification for compounded tirzepatide. Scripts are typically issued within 24–48 hours of consult.
- Is compounded tirzepatide the same as Mounjaro?
- Both contain tirzepatide — the same dual GIP/GLP-1 receptor agonist molecule. They differ in regulatory pathway (Mounjaro is ARTG-registered; compounded tirzepatide is dispensed under TGA SAS-B), in delivery format (Mounjaro is a single-use pre-filled pen; compounded tirzepatide is usually a multi-dose vial with syringes), and in dose flexibility (Mounjaro has fixed pen strengths; compounded versions can be titrated more granularly).
- Am I eligible for tirzepatide in Australia?
- Australian prescribers generally consider tirzepatide for adults (18+) with BMI ≥30, or BMI ≥27 with at least one weight-related comorbidity (type 2 diabetes, hypertension, dyslipidaemia, obstructive sleep apnoea). Final eligibility is a clinical decision at consultation. Tirzepatide is not prescribed in pregnancy, breastfeeding, with a personal/family history of medullary thyroid cancer or MEN-2, or with pancreatitis history.
- How fast does tirzepatide work for weight loss?
- Most people see appetite suppression in the first 1–2 weeks and measurable weight loss within 4–8 weeks. Trial data shows average weight loss of around 20–22% of body weight at the 15 mg dose over 72 weeks — but individual response varies and depends on dose titration, diet, and physical activity.
- What are the side effects of tirzepatide?
- The most common side effects are gastrointestinal during dose titration: nausea, reflux, constipation, diarrhoea, decreased appetite. These usually settle within 1–2 weeks at each dose step. Less common but more serious risks include pancreatitis, gallbladder disease, and severe hypoglycaemia (especially when combined with insulin or sulfonylureas). Discuss your full medical history with your prescriber.
- Can I get tirzepatide on telehealth in Australia?
- Yes. Telehealth tirzepatide prescribing is a routine pathway used by AHPRA-registered Australian doctors. The consult is by video or phone from anywhere in Australia. If baseline pathology is required, you visit any local collection centre. Cold-chain delivery to your address typically takes 2–4 business days after dispense.
