Hi! You know, to give you the best answer, I think I should ask you a few questions first that will help define the problem and the situation.
I am unclear: why is your interest in this one brand particularly? As opposed to other brands?
Your son is now at the age where what is often diagnosed as ADHD in childhood begins to show itself as a mood disorder like Bipolar Disorder. Is that's what is happening? You mention mood disorder: what has he been diagnosed with?
How many different medications have been tried? And were they all for ADHD or for mood disorders also?
Was there trauma or abuse in his childhood? What about alcohol or dysfunction in the family when he was growing up? Would these be factors in his situation?
Has he had any psychotherapy? Is he getting any treatment right now? If so, what type? How is it going?
If not, when was the last treatment? What type of treatment was it? Was it helpful?
Any extra information that will help, feel free to share.
