Methylin Information

Methylphenidate is a central nervous system stimulant. It affects chemicals in the brain and nerves that contribute to hyperactivity and impulse control.

Methylphenidate is used to treat attention deficit disorder (ADD), attention deficit hyperactivity disorder (ADHD), and narcolepsy.

Methylphenidate may also be used for purposes not listed in this medication guide.

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

Do not use methylphenidate if you have used an MAO inhibitor such as furazolidone (Furoxone), isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam), or tranylcypromine (Parnate) 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, overactive thyroid, severe high blood pressure, tics or Tourette's syndrome, angina, heart failure, heart rhythm disorder, recent heart attack, a hereditary condition such as fructose intolerance, glucose-galactose malabsorption, or sucrase-isomaltase deficiency, or severe anxiety, tension, or agitation. Methylphenidate may be habit-forming and should be used only by the person it was prescribed for. Never share methylphenidate with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it.
