Invega and Gynecomastia: What’s the Problem?

The atypical antipsychotic Invega was approved by the U.S. Food & Drug Administration (FDA) in 2006. Three years later, the agency cleared Invega Sustenna, an injectable form of the drug. The active ingredient in both medications is a metabolite of Risperdal, another antipsychotic that is also marketed by Johnson & Johnson’s Janssen Pharmaceuticals unit. As such, Invega works in a similar manner to Risperdal, and carries many of the same risks.

In recent years, a number of studies have suggested that Risperdal may be associated with the development of gynecomastia in men and boys.

  • 1999: Research that appeared in the journal Psychopharmacology discussed the case of a patient who developed gynecomastia while taking 0.5mg of risperidone (the generic name for Risperdal) along with fluoxetine (an antidepressant sold under the brand name Paxil).
  • 2006: A paper published in the Journal of Child and Adolescent Psychopharmacology reported that teenagers treated with Risperdal experienced “persistent elevated levels of prolactin.” Prolactin a hormone related to female breast development and lactation. Excessive levels in males have been linked to the development of gynecomastia.
  • 2009:  A study that appeared in the Journal of Clinical Psychopharmacology  concluded that: “Risperidone administered to adolescents at doses commonly used for the treatment of psychotic symptoms can strongly increase prolactin levels, with clinical consequences such as gynecomastia and/or galactorrhea.”

What is Gynecomastia?

Gynecomastia is a condition marked by the excessive growth of breast tissue in men and boys. In some cases, it may even be accompanied by lactation. Symptoms can include:

  • Swollen breast tissue
  • Pain
  • Tenderness
  • Discharge from one or both breasts

While not life-threatening, gynecomastia can be an extremely painful and embarrassing condition. The excess breast tissue will not go away, even with weight loss or when a patient stops using Invega.  Some gynecomastia victims have reportedly developed female-like breasts as large as a 44DD cup. When the condition becomes this serious, patients may be forced to undergo surgical procedures, including liposuction or mastectomy, to remove their excess breast tissue.
