What is the most important information I should know about methylphenidate?

Do not use methylphenidate if you have used an MAO inhibitor such as isocarboxazid (Marplan), tranylcypromine (Parnate), phenelzine (Nardil), rasagiline (Azilect), or selegiline (Eldepryl, Emsam) within the past 14 days. Serious, life-threatening side effects can occur if you use methylphenidate before the MAO inhibitor has cleared from your body. Do not use this medication if you are allergic to methylphenidate or if you have glaucoma, tics (muscle twitches) or Tourette's syndrome, depression, or severe anxiety, tension, or agitation (methylphenidate can make these symptoms worse). Methylphenidate may be habit-forming and should be used only by the person it was prescribed for. Methylphenidate should never be shared with another person, especially someone who has a history of drug abuse or addiction. Keep the medication in a secure place where others cannot get to it.
