Risperdal is an anti-psychotic drug. Its active ingredient is risperidone. Risperidone affects levels of dopamine and serotonin, which are neurotransmitters that affect mood and behavior. Risperdal is used to treat schizophrenia and symptoms of bipolar disorder in adults; in children, it is used to treat irritability associated with autism.

Risperdal, which is manufactured by a Johnson & Johnson’s subsidiary, Jansen Pharmaceuticals, Inc., has been linked to the development of gynecomastia in young males, which is the development of excess male breast tissue. Symptoms of male breast growth associated with Risperdal may include swollen breast tissue, breast tenderness and pain, and nipple discharge.

If you or someone close to you has used Risperdal, Risperidone, or Invega before the age of 18, is male, and suffered noticeable breast growth or a diagnosis of gynecomastia, please contact Phoenix Arizona Mass Tort Product Liability Attorney Steve Leshner for a free consultation.
