Psychchiatric Warnings on Flu Drugs Tamiflu and Relenza?

An FDA panel is reviewing recommendations that psychiatric warnings be added to the labels of two flu drugs, Roche's Tamiflu and GlaxoSmithKline's Relenza.

The label warnings on Tamiflu would include "in some cases, these behaviors resulted in serious injuries, including death, in adult and pediatric patients." The Relenxa box label would be updated to include: "reports of hallucinations, delirium and abnormal behavior" seen in some patients taking the drug.

The adverse events have occurred. The FDA isn't sure whether the drugs are the cause, or a disease, or a combination of the two. Roche and GSK say it's not the drugs.
Wonder if any whistles will blow on this one?
