Risperdal can have side effects but it is widely used in children and serious problems are very rare. The dose your son is taking is low. If it helps your son then I would have no problem continuing treatment. Regarding the risks of Risperdal with children under 18, the warnings are true, but actual risk is very low – lower if the doses are small, as in this case. If the personal physician would like, checking a liver profile after a month of treatment should indicate if the drug is being tolerated. However, the potential risk for NMS (neuroleptic malignant syndrome) is not testable. Ultimately, the risks are far outweighed by the benefits of this medicine
