A new study appears to lend credence to dozens of Risperdal lawsuit claims that allege the drug caused gynecomastia, or male breast development, in men and boys. The study, which was recently presented at the American Association for Geriatric Psychiatry (AAGP) 2014 Annual Meeting, was the first and largest of its kind to take a look at the association between Risperdal and gynecomastia.

According to a report from MedScape Medical News, the study drew data on more than 1 million people included in a large insurance database, and identified 8,285 cases of gynecomastia. The study found that patients who had taken Risperdal or Invega (an antipsychotic that contains an active metabolite of risperidone) had a 69% increased risk of developing gynecomastia compared to non users. Further analysis revealed that those who used Risperal or Invega also had a higher risk of developing gynecomastia than did patients treated with Zyprexa or Seroquel.

The study only involved older patients, but its authors surmised that their findings would also apply to boys and younger men.

“If everything is the same in terms of efficacy in these antipsychotics, especially for younger men who may have more problems with this psychologically, then I think it may be better to choose something other than risperidone,” one of the study’s authors told MedScape.

Gynecomastia Alleged in Risperdal Lawsuits

The Medscape article points out that cases of Risperdal gynecomastia have been cited in medical literature and reported to the U.S. Food & Drug Administration’s (FDA) adverse event database. The injury is also cited in dozens of Risperdal lawsuits pending in a consolidated litigation underway in Pennsylvania Court of Common Pleas in Philadelphia. They are among some 200 claims that have been filed on behalf of alleged victims of Risperdal side effects.

It is believed that Risperdal can cause gynecomastia in men because it stimulates the production of prolactin. Prolactin is a hormone that is tied to breast development and lactation in women.
