Risperdal (risperidone) is an antipsychotic medication manufactured by Janssen Pharmaceuticals, a division of Johnson & Johnson. It has been linked to serious side effects, including gynecomastia in male children and adolescents.

Gynecomastia and Risperdal

Gynecomastia is the benign enlargement of breast tissue in males. While gynecomastia can occur naturally, approximately 10%-25% of gynecomastia cases are estimated to result from the use of medications.

Risperdal was approved by the FDA in 1993 for the treatment of schizophrenia and acute mania, which is a term used to describe mixed episodes of bipolar disorder. Risperdal has also been prescribed off-label to treat dementia, as well attention deficit disorder (ADD), attention deficit hyperactivity disorder (ADHD), depression, anxiety, and autism in children

Risperdal Gynecomastia Studies

A 2006 published in the Journal of Clinical Psychopharmacology reported that adolescents who took Risperdal exhibited significantly high levels of prolactin. Prolactin is a hormone that stimulates milk production and breast development and can lead to gynecomastia for men.

A 2009 study published in the Journal of Child and Adolescent Psychopharmacology found that elevated prolactin from Risperdal use could persist for two years.

In addition to gynecomastia, Risperdal has been linked to severe side effects including diabetes, bone loss, sexual dysfunction, neuroleptic malignant syndrome, and pituitary tumors.
