Metformin shortage worsens

The TGA has announced that all extended release Metformin products are now classified as having limited availability.
On 17 June, 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, were still listed as being available in regular supply.
Some pharmacies say they've been grappling with supply issues since January. All sponsors of the drug appear affected. Some observers believe global suppliers have diverted stock from Australia to more profitable markets in response to PBS subsidy cuts.
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.
"Consumers should contact their treating doctor if they are unable to obtain metformin extended release tablets that they have been prescribed," continues the advice from the TGA.
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.
