Friends star Matthew Perry was taken to hospital this week suffering a seizure after taking prescription drugs, it has been revealed.
The actor was rushed into an LA hospital by ambulance after an emergency 911 call.
Emergency tests showed traces of barbiturates in his system, the News Of The World reported.
He tested negative for illegal drugs such as cocaine and cannabis.
His spokeswoman said: "He was admitted because he had an adverse reaction to some prescribed medication.
"His doctor wanted him in the hospital where they could observe his condition.
"But he's fine."
Matthew, 35, has a history of substance abuse, after becoming addicted to the painkiller Vicodin eight years ago.
He has checked into treatment clinics on several occasions, but said in 2001 that he had kicked his addiction.
Barbiturates are normally prescribed for anxiety or sleeping problems.
