PBS Metformin Cost – What You Actually Pay in 2025

If you have type 2 diabetes, the first question on your mind is probably "How much will my metformin cost?" The answer isn’t a single figure because it depends on the PBS schedule, the brand you pick, and whether you use a regular pharmacy or an online service. In this guide we break down the numbers, explain the subsidy, and give you three simple tricks to keep the bill low.

Understanding the PBS Subsidy

The Pharmaceutical Benefits Scheme (PBS) caps the price that Australian patients pay for most medicines, including metformin. As of 2025 the PBS generic price for a 30‑day supply of 500 mg tablets is about $9.80. If you’re on the higher‑strength 850 mg or 1000 mg tablets, the PBS price climbs to roughly $13‑$15 for the same month’s supply. The government covers the rest, so you never see the full retail price unless you go outside the PBS list.

What many don’t realize is that the PBS price applies only when you present a valid prescription at a pharmacy that participates in the scheme. Some specialty pharmacies, especially those that ship overseas, may charge the full retail cost unless they specifically list the PBS price.

Tips to Keep Your Metformin Bill Low

1. Ask for a generic name. Metformin is available under many brand names, but the PBS price is the same for any generic version. If the pharmacist offers a brand‑name option, politely demand the generic – you’ll stay at the PBS rate.

2. Use bulk packs when possible. Many pharmacies sell a 90‑day supply for the same PBS co‑payment as a 30‑day pack. This reduces pharmacy‑visit costs and saves you trips to the counter.

3. Consider reputable online pharmacies. Sites that partner with Australian pharmacies can fill your prescription and still honor the PBS price. Look for clear evidence of PBS pricing on the product page and verify the pharmacy’s Australian registration number.

Bonus tip: If you hold a Concession Card or a Health Care Card, the PBS co‑payment drops to about $4.60 per prescription. Make sure your card details are up to date at the pharmacy.

Another practical move is to check the PBS schedule online before you fill the script. The schedule lists the exact amount you’ll pay for each strength and dosage form. If a pharmacy quotes a higher price, ask why – they may be charging a non‑PBS surcharge, which you can often avoid.

Finally, keep an eye on seasonal promotions. Some big‑chain pharmacies run “PBS price guarantee” weeks where they promise to match the PBS price even for brand‑name packs. While the savings aren’t huge, every dollar counts when you’re taking a daily medication.

By understanding how the PBS works and using these simple strategies, you can keep your metformin cost at the government‑set minimum and free up cash for other health needs. Stay informed, ask the right questions, and you’ll never overpay for a drug that’s essential to your daily routine.
