"after being diagnosed with pdd/adhd, it was suggested that my son (then 5) try intuniv.  initially, he was extremely lethargic, not being able to get out of bed.  this was only a day or two.  we noticed a difference within days and a completely focused child!  however, after a few weeks he was becoming extremely obsessed with germs constantly washing his hands.  we counted 14 times in a 15 min span!  his poor little hands were raw and chafed a bright red.  it didn&#039;t matter, he kept washing.  our pediatrician referred us to a psychiatrist (as he had never experienced this side effect) and the psych said that it was due to the pdd.  we took him off.  if it hadn&#039;t been for the side effects, the intuniv worked quite well."
