Concerta and medications

My son was changed from Adderall to Concerta. He started having a lot of side effects on 18mg. I told the doctor and he doubled the dose to 36mg. In three days, he went totally out of control. In the following 4 days, we had 3 emergency room visits, two hospitals and two ambulance rides. Now I am facing lots of bills and no help from the doctor. My son's side effects were weight loss, loss of appetite, mervousness, fast heartbeat, unusual sadness, irritability, dilated pupils, hallucinations, twitching, temors, throwing up, yelling at me, nose bleeds, behavior changes, and dizziness. He now is off all ADHA medications. Please read what the side effects are and stop the medication if they show up.

Male 26, Dose 36 mg Concerta daily

This medication has been highly effective in treating my inattentiveness or ADD as I am diagnosed.

I experience slight nervousness while taking the medication - this side effect seems to be worse when I take caffeine.
Thus I try to avoid coffee, etc.

Overall, the medications benefits far outweigh the side effect.
