What is generic Metformin?
Metformin belongs to the biguanide class of drugs and works by reducing liver glucose production and improving insulin sensitivity. The active ingredient biguanide is identical in every reputable generic version, so clinical effectiveness matches the brand‑name product (Glucophage).
The drug comes in 500mg, 850mg, and 1000mg tablets, usually taken twice a day with meals. For most adults, the starting dose is 500mg twice daily, titrated up to 2000mg per day based on blood‑sugar response and tolerance.
Legal and safety checkpoints
In Australia, the Therapeutic Goods Administration (TGA the national regulator for medicines and medical devices) must approve any pharmacy that sells prescription‑only medicines online. A legitimate site will display its TGA registration number (e.g., 12345‑1234) and a link to the TGA’s public register.
Prescription requirement: Metformin is a Schedule4 drug, meaning a valid prescription from a registered Australian doctor is mandatory. Reputable online pharmacies ask you to upload a scanned prescription or have your doctor send it electronically. If a site says “no prescription needed,” it’s a red flag.
Pharmacist verification: The pharmacy should have a licensed pharmacist review every order before it ships. Look for statements like “All prescriptions are checked by a registered pharmacist” on the checkout page.

How to spot a trustworthy online pharmacy
Use this checklist before you add anything to your cart:
- Check the URL ends with
.au
and shows a padlock icon. - Confirm the TGA registration number on the “About Us” page.
- Verify the pharmacy lists a physical Australian address and a local phone number.
- Read the shipping policy notice for delivery times, fees, and handling of controlled substances.
- Make sure a qualified pharmacist signs off each prescription.
- Look for clear pricing that includes GST (Goods and Services Tax).

Common pitfalls and how to avoid them
