The cost of weight loss medications in Australia can vary widely depending on the type (e.g., prescription vs over-the-counter), dosage, pharmacy, and whether it’s subsidised for a related condition like type 2 diabetes. As of November 2025, these are not subsidised under the Pharmaceutical Benefits Scheme (PBS) specifically for weight management or obesity, so most patients pay the full private price. Based on current market estimates, here’s a breakdown:
Prescription Weight Loss Medications
These require a doctor’s assessment and script, and are typically used for adults with a BMI ≥30 kg/m² (or ≥27 kg/m² with comorbidities). Monthly costs often range from $100 to $600.
- Oral appetite suppressants or combination therapies: Around $80–$250 per month for a standard supply.
- Injectable hormone-based therapies (e.g., weekly or daily doses mimicking gut hormones): Typically $130–$500 per month, with higher-end options for advanced dual-action formulas reaching $300–$600. Starter packs or pens can add initial costs.
- Factors affecting price: Brand vs generic (where available), quantity prescribed, and location (e.g., urban pharmacies may offer discounts). Supply shortages for popular injectables can drive up prices or lead to unavailability.
- Subsidies for comorbidities: If prescribed for type 2 diabetes (not just weight loss), some options may qualify for PBS subsidies, reducing costs to $30–$40 per script for eligible concession card holders or around $40–$100 for general patients. However, this doesn’t apply to pure weight management use.
Over-the-Counter (OTC) Weight Loss Medications
These are available without a prescription at pharmacies like Chemist Warehouse and focus on fat absorption reduction. Expect to pay $50–$100 per month for a typical course, though effectiveness is generally lower (2–9% weight loss) compared to prescriptions. Side effects like gastrointestinal issues can influence ongoing use.
Additional Considerations
- Total out-of-pocket expenses: Factor in consultation fees (e.g., $50–$100 for a GP or telehealth visit) and any monitoring tests. Long-term use (recommended for sustained results) can add up to $1,200–$7,200 annually.
- Affordability barriers: AJGP highlights that high costs limit access for many Australians, with calls for expanded PBS coverage. Private health insurance rarely covers these medications.
- Value and effectiveness: While costs are significant, studies show 5–20% weight loss possible with prescriptions when combined with lifestyle changes, potentially offsetting health expenses from obesity-related issues.
- Variations by pharmacy: Shop around—online pharmacies or bulk buys may offer 10–20% savings. Prices can fluctuate with inflation or global supply (e.g., injectables have seen increases due to demand).
