A 2001 paper by G. Masi et al. published in Journal of Child and Adolescent Pharmacology begins its abstract as follows: “Although hyperprolactinemia is a common side effect during risperidone treatment in adult patients, no information is available on young children.”

To be clear, hyperprolactinemia is a condition characterized by elevated blood levels of prolactin, the hormone responsible for breast development and milk production.  As such, one negative side effect of this condition is gynecomastia – male breast growth, an ailment that can be very detrimental to a patient’s psychology, especially in children.

The title of this paper was “Prolactin levels in young children with pervasive developmental disorders during risperidone treatment.” and understandably, aimed to “report on serum prolactin levels in 25 young autistic children (22 males and 3 females, age range 3.9-7 years, mean age 4.10 years) during treatment with risperidone (dosage range 0.25-0.90 mg/day, mean dosage 0.52 mg/day).” (hyperlinks added)

Blood levels of prolactin were tested after these children used risperidone (Risperdal) for 10 weeks.  Results showed that while “Six children (24%) showed prolactin levels lower than 15 ng/mL, which is the upper normal level; eight children (28%) had prolactin levels higher than two times the upper limit (30 ng/mL).” (emphasis added)

Unfortunately, the manufacturer of Risperdal has failed to adequately warn users of the risk for hyperprolactinemia and ensuing gynecomastia, and accordingly, a number of Risperdal lawsuits have been filed.  If you or a loved one used Risperdal and suffered male breast growth or another complication as a result, you too may be entitled to significant financial compensation.  For a free, no-obligation case consultation, contact our team of Risperdal lawyers at the information provided below.  We have the experience, resources, and compassion required to win the justice you deserve.
