WASHINGTON (Reuters) - U.S. regulators are studying the deaths of 12 children in Japan who took Roche AG's flu-fighting drug Tamiflu, officials said on Thursday, but they said it was difficult to tell whether the drug played a role in any of the cases.
The U.S. Food and Drug Administration said it was "concerning" that 32 psychiatric events, such as hallucinations and abnormal behavior, also had been reported in children who took Tamiflu, which is in high demand because it is considered to be one of the best defenses against avian flu in people.
