Hi everyone. My son (age 12)'s developmental paediatrician today suggested Risperidone for him. He has ASD, ADHD, anxiety and is profoundly gifted academically. He's at an academically selective school here in Australia (like a grammar school), who are very supportive, but his outbursts and ongoing defiance are really wearing everyone down. He can go from nil to 100 in a second; it's so stressful. He's previously responded well to Fluoxetine but the paed thinks we need to bring out the bigger guns. Would be keen to hear of others experiences with Risperidone and whether it helped with your child's irritability / anger? How long were they on it? How were the side effects? The paed warned me about weight gain and also some cognitive effects. Thanks so much
