Since I already have read two posts today about parents opening the Strattera capsule to give to their children, I feel there is a need for an attention-getting thread about the dangers of this method. The contents of Strattera, when opened, can cause serious damage to the esophagus. Never open Strattera or Concerta. But you CAN open Adderall XR and Metadate CD, but make sure, your child does not bite on the little granules, because this can cause an overdose. They need to swallow it.
