Concerta® (methylphenidate extended release) is a prescription medication that is used for the treatment of attention deficit hyperactivity disorder (ADHD). It is designed to be released slowly over time. Because the medication is released slowly, it can be taken just once a day, eliminating the need to take medication at school or work.
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. Keep track of how many pills have been used from each new bottle you receive. Methylphenidate is a drug of abuse and you should be aware if any person in the household is using this medicine improperly or without a prescription.
