government is stockpiling relenza, page-13

If correctly stored, the pandemic use expiry date is reported to be 2 extra years. GL anyone asking for a later expiry date as I expect that these orders are from the Australian pandemic supplies. There will be some pressure to sell older stock now rather than loss of that chance after normal expiry.

Anyone with expired Relenza should ensure that use is safe.

If too many pigs or ducks start sneezing, use after normal expiry may not be as great a concern as no effective antiviral at all.
