since taking this drug my son is making abnormal neck movements while standing ,sitting etc and started talking to himself which was not done before. Prior to calling medicines he was slightly depressed and used to get irritable. Now, he says he talks to people and is obsessed with cleaning etc. Can we stop this medicine for sometime and observe him?
