A study conducted by researchers at Duke University identifies a link between Risperdal and gynecomastia, or the abnormal growth of breast tissue in boys and young men. The researchers also determined that the gynecomastia risk associated with Risperdal is greater than with other antipsychotic medications. The same study found that some girls and young adult females who took Risperdal began lactating before puberty.
