How did you know when to take her off the medication, Shannon?

My oldest son is not on any medication and he is quite explosive at times. I can barely control him and that is what is frightening me as what is he going to be like as a teenager. Other people cant control him at all. I do have an appointment with the a paed but it is not until the end of the month. Basically I am asking for help on what to do as I have no idea.
