The authorities reported the first case in the nation of a teenager who took Tamiflu and injured himself by jumping from a building, allegedly under the hallucinogenic effect of the flu medicine, Yonhap News Agency reported on Saturday.

A 14-year-old teenager, identified as Lee, was discovered with fracture in his bones and head injuries on Oct. 30 in Gyeonggi Province at the entrance of his apartment.

The day before, the boy developed high fever and was prescribed with Tamiflu at a hospital. He came back home, took the medicine and went to bed.

The boy apparently jumped from the six-floor window of his apartment later. But he didn't remember anything about the incident.

In 2005 and 2007 in Japan, there were reports that teenagers who took Tamiflu threw themselves from a building, apparently under the influence of hallucination, Yonhap said.

The authorities are currently looking into the case.
