m not sure if Zofran is used in
children but you could ask. Tetrabenzene is used but that has some serious
side effects so that might not be for children either. But there are other medications as well. Clonidine in patch form (Catapres) is especially helpful for tic like motions (tardive tourreticism which is a variant of tardive dyskinesia I have as well). I am on Tenex which is helpful as well. I believe both of those are used in children.
