Trial: Man Claims Drug Made Him a Sex Addict

A trial is under way for a Frenchman who claims GlaxoSmithKline's Parkinson’s disease drug turned him into a sex addict.

Didier Jambart, 52, started taking the drug ReQuip in 2003 to treat his Parkinson's. Shortly after, he said, he was full of energy, and his behavior changed, causing him to cruise for sex online, and engage in risky sexual activities. He said his risk-taking also led to him getting raped.

The father of two said it ruined his life and his family, which is why he is suing the British pharmaceutical giant for £390,000, or $625,000, according to London’s Daily Mail.

A representative for the company said analysis of the drug did not show the side effects that Jambart describes having, but he admitted there could be an "extremely rare reaction" causing his behavior.
