In 2005, a team of Polish researchers published a study titled “Prolactin secretion disturbances in schizophrenic patients treated with 2nd generation antipsychotics–risperidone and olanzapine” in Psychiatria Polska that aimed to further elucidate the connection between the use of second-generation antipsychotics and elevation of prolactin.  Prolactin is a hormone in the body responsible for breast development and milk production, and elevation of prolactin – a condition called hyperprolactinemia – can lead to gynecomastia, the development of breasts in men.

As such, this team “[compared] the prevalence of hyperprolactinemia and its clinical symptoms in three groups: (1) patients with schizophrenia treated with risperidone, (2) those treated with olanzapine and (3) the control group.”  In all, 60 schizophrenic patients were studied (26 treated with Risperdal, 34 treated with Zyprexa), and the prolactin levels in these patients were compared to 38 healthy, non-medicated patients.

Researchers found that “Hyperprolactinemia was established in 92.3% patients treated with risperidone and in 76.5% patients treated with olanzapine and in 2.6% subjects of the control group”, drawing a clear connection between risperidone (Risperdal) use and hyperprolactinemia, and between Zyprexa use and hyperprolactinemia.

Sadly, the manufacturer of Risperdal (Janssen Pharmaceuticals, Inc.) has failed time and again to warn users of the risk for hyperprolactinemia and gynecomastia associated with Risperdal use.  As a result, a number of Risperdal lawsuits are currently being filed.  If you or a loved one used Risperdal and suffered gynecomastia as a result, you too may be entitled to significant financial compensation for your undue injury and suffering.  For a free, no-obligation case consultation, contact our team of Risperdal lawyers at the information provided below.  We have the compassion, resources, and skills required to win the justice you deserve.
