My son has been on Risperidone for several years. Recently I heard from another patient that he was taken off it due to heart problems. I have brought the concern to the doctor but he is not sure what the other patient was referring to with the medicine. As my son has gotten older (and started high school) he's on an increased dose and so my concerns have increased.
Cardiovascular side effects have frequently included tachycardia, hypertension, and hypotension. Palpitation, AV block, and myocardial infarction have also been reported. Ventricular tachycardia, angina pectoris, premature atrial contractions, T wave inversions, ventricular extrasystoles, syncope, edema, ST depression, myocarditis, venous thromboembolism, and bradycardia have been reported rarely. Prolongation of the QT interval has been reported in some patients. One fatal cardiac event following initiation of risperidone (the active ingredient contained in Risperdal) therapy has been reported.
