Metformin supply crisis worsens

Availability of all extended release products now limited: TGA

The crisis over low supply of metformin has worsened, with all extended release products now being classified as having limited availability.

On 17 June the TGA advised that two out of eight Metformin extended release products still had regular availability:

  • DIABEX XR 1000 metformin hydrochloride 1000 mg extended release tablet blister pack and,
  • DIAFORMIN XR 1000 metformin hydrochloride 1000 mg extended release tablet blister pack.

However this has now been changed, with the latest advice warning these products too now were classified as ‘limited availability’.

The TGA is advising health professionals to direct enquiries regarding supply of metformin extended release tablets to the product sponsor.

“Pharmacists and wholesalers are requested to order minimum quantities of stock from suppliers to try and minimise the chance of further shortages as supplies become available,” the TGA advice states.

The shortages are due to some suppliers having limited or no stock, resulting in unexpected increased demand on other suppliers which they are not able to fully meet at this time. Suppliers are working closely with their manufacturers to expedite delivery of stock.
