In 2003, the results of a small study titled “Risperidone-associated hyperprolactinemia: evaluation in twenty psychiatric outpatients.” by S. Brunelleschi were published in Psychopharmacological Research (the official journal of the Italian Pharmacological Society), aiming to elucidate a potential link between use of Risperdal (risperidone) and hyperprolactinemia (elevated prolactin levels).  For clarity, prolactin is the hormone responsible for breast development and milk production.  In males, elevated prolactin levels can lead to gynecomastia – male breast growth, which can be very troublesome.

Explaining their research, the study team wrote “We decided to evaluate the effects of risperidone on serum prolactin levels and prolactin-related adverse effects in 20 outpatients of an Italian community psychiatric service. Patients enrolled in this study were on risperidone (2-8 mg per day; mean dose=4.15+/-0.4 mg per day) treatment in the period May-November 2002. The 20 patients, 13 women and 7 men (mean age=36.38+/-3.2 years for women and 29.7+/-2.2 for men) who accomplished inclusion criteria, participated in the study after giving informed written consent.”

Results showed that “Raised prolactin levels were observed in 13 (9 women and 4 men) out of 20 patients, but only 8 patients presented prolactin-related adverse effects, libido reduction being the most frequent.”  This study demonstrating that “risperidone enhanced serum prolactin in 65% of patients” could be used as evidence in a Risperdal lawsuit to demonstrate to court that the manufacturer of Risperdal knew, or should have known the risks associated with its product.

As such, if you or a loved one used Risperdal and suffered gynecomastia or another complication, you too may be entitled to significant financial compensation for your injury and undue suffering.  For a free, no-obligation case consultation, contact our team of Risperdal lawyers at the information provided below.  We have the compassion, experience, and resources required to win the justice you deserve.
