Canada wrestles with expiring-antiviral issues
Faced with about 9 million expiring doses of the antiviral drug Tamiflu worth $18 million, Canadian officials are exploring the options, according to the Toronto-based Globe and Mail. Public health leaders are faced with three options: destroy the expired doses, reprocess them (to replace the expired ingredients) to prolong shelf life, or make do with remaining stockpiles that won't expire soon. A federal official said a decision on the antiviral stockpiling should come this fall.

Study proposes Tamiflu dosing for preemies
Before its emergency use authorization expired Jun 23, oseltamivir (Tamiflu) was at times prescribed to treat children under 1 year old. Researchers used their experience with 32 premature newborns exposed to the pandemic virus to establish a dosing protocol for the drug. Their results indicate that a twice-daily dose of 1.0 mg/kg in premature neonates produced drug exposures similar to that in older children receiving twice-daily doses of 3.0 mg/kg.
