You should not take this medicine if you are allergic to dexmethylphenidate or methylphenidate (Ritalin, Concerta), or if you have:

  • glaucoma;
  • a personal or family history of tics (muscle twitches) or Tourette's syndrome; or

Some stimulants have caused sudden death in certain people. Tell your doctor if you have:

  • heart problems or a congenital heart defect;
  • high blood pressure; or
