I looked up those particular medications and I believe they can cause tardive dyskinesia, a neurological disability that is a form of Parkinsonianism. I have
tardive dyskinesia and the treatments that have been most helpful to me are
Zofran, the natural remedy as identifed in clinical studies rhodiola and Clonidine. I don't know if the first two are used in children but the Catapres (Clonidine) patch is and it can be very helpful.
