Didier Jambart, of Nantes, France is suing UK drug maker GlaxoSmithKline, claiming Requip turned into a gay sex addict, the AFP reported.

Jambart, who suffers from the nervous system disorder Parkinson's disease, began taking Requip in 2003.

The 51-year-old civil servant's lawyers say Jambart became addicted to Internet gambling and lost his family's savings while taking the drug.

The father of two claims he became addicted to gay sex and began exposing himself on the Internet, which eventually led to him being raped.

Lawyers say Jambart's behavior stopped in 2005 after he stopped taking Requip.

Glaxo is being sued for 450,000 euros ($610,000) in damages.

The drug's label warns in part: “You should know that some people who took medications such as ropinirole developed gambling problems or other intense urges or behaviors that were compulsive or unusual for them, such as increased sexual urges or behaviors.”

Jambart's attorneys say this warning only began appearing in 2006, too late for their client, who blamed a demotion at his defense ministry job on his erratic behavior.
