Japanese health officials will open a new investigation on the link between Tamiflu flu medication and unusual behavior in people who have used the drug after recent deaths.

Japan reviewed Tamiflu-related deaths images 1 "We need to consider the allegations that accidents related to children happen regularly," Health Minister Hakuo Yanagisawa said.

Previously, Japan had stated that there was no clear evidence of a causal link between Tamiflu and accidents. However, the country said it would review the argument after asking importers Tamiflu to warn non-prescription doctors for children.

The request was made after the event of dozens of young children jumping upstairs after being treated with this medicine. In the recent case, a 14-year-old boy died from jumping from the 11th floor of an apartment building.

Roche, the manufacturer of the anti-influenza drug, has repeatedly denied any link between these accidents with Tamiflu.
