Hi there. Yes, completely agree. Withdrawel dyskinesia can happen when risperidone is stopped quickly. You want to tell your doctor immediately. They can go away over time but could take a while. Tardive dyskinesia is a bit different and may not go away. Definately give your doctor a call about this situation.
Obviously, be religious about giving that medication at the appropriate time each day. If he does eventually discontinue it, a very slow taper is best.
good luck. Always frightening as a parent. peace
