(CNN) Johnson & Johnson will have to pay $8 billion in punitive damages after a man claims the company didn't warn young men that the drug Risperdal could grow breasts, a jury said Tuesday, according to Reuters.

Nicholas Murray, 26, previously won $680,000 in the case over the antipsychotic drug Risperdal in the Philadelphia Court of Common Pleas.

Murray says he developed breasts after he began taking Risperdal in 2003 when a psychologist diagnosed him with autism spectrum disorder, according to Reuters.

Murray's lawyers, Tom Kline and Jason Itkin said in a statement the "jury told Johnson & Johnson that its actions were deliberate and malicious."

"The conduct that the jury saw in the courtroom, was clear and convincing that J&J disregarded the safety of the most vulnerable of children. This is an important moment, not only for this litigation, but for J&J, which is a company that has lost its way."
