Risperdal

Risperdal has been linked to gynecomastia, a medical condition where boys develop female breasts.

A medical study showed that some boys who took Risperdal (or its generic version, risperidone) had high levels of a hormone that stimulates production of milk in the breast. If your son took Risperdal and developed female breasts, lactated, required breast reduction surgery or had noticeable weight gain, you owe it to yourself to find out.

A medical study published in December in the Journal of Child and Adolescent Psychiatry showed that some adolescent boys who took Risperdal or its generic version, risperdone, exhibited high levels of the hormone prolactin, which stimulates production of milk in the breast. The study found that long-term treatment increased prolactin levels.

Risperidone use may also affect sexual function and lead to enlarged breasts (gynecomastia) in males, the study found. Other severe side effects include weight gain, diabetes and heart abnormalities.

In the study, researchers studied the effect of long-term risperidone use in 98 males aged 10 to 20 who have autism or disrupted behavior disorder. The study concludes that boys on risperidone are 72 times more likely to have elevated prolactin than those who don’t take the drug.
