Metformin shortages continue with 19 products unavailable

GSK has worked with the Department of Health to ensure an alternative MMRV vaccine will be available. So the shortage, from April to November, is unlikely to disrupt vaccinations through the National Immunisation Program. 

To deal with the metformin constraint, the TGA is allowing the importation of a brand not currently listed on the Australian Therapeutic Goods Register, Yaltormin SR 500mg and 1000mg, until the end of March.

  • Metex XR 500mg: Supply could be impacted until 15 August.
