My son, kevin, had a bad reaction to concerta 36mg. severe anxiety, fast heart beat, cold sweats, clammy hands and shaking, stomach tightening and nausea feeling. lexamil 10mg was prescribed alongside for depression.

Concerta: Is he diagnosed with ADHD? Since ADHD is very over-diagnosed I would wonder how much care was put into insuring the diagnosis was correct. Was he started on a dose of 36 mg or was he started on a lower dose and titrated upwards? Concerta is a stimulant but it usually slows down people with ADHD and accelerates most other people.

intolerance: That sound like a substantial bad side effect, not everyone is able to tolerate stimulants, it would be worth trying the other major class of stimulants-mixed amphetamne salts-or Adderall-a bad reaction to one type does not necessarily mean that he would have a negatinve rxn to the other type and Vyvanse is different enough from the concerta to probably be worth trying too.
