Concerta (methylphenidate) is a central nervous system stimulant. It affects chemicals in the brain and nerves that contribute to hyperactivity and impulse control. Concerta extended-release tablets are used to treat attention deficit disorder (ADD), attention deficit hyperactivity disorder (ADHD), and narcolepsy. Concerta may also be used for purposes not listed in this medication guide.

You should not use Concerta if you have glaucoma, tics or Tourette’s syndrome, or severe anxiety, tension, or agitation. Methylphenidate may be habit-forming, and this medicine is a drug of abuse. Tell your doctor if you have had problems with drug or alcohol abuse. Stimulants have caused stroke, heart attack, and sudden death in people with high blood pressure, heart disease, or a heart defect. Do not use Concerta if you have used an MAO inhibitor in the past 14 days, such as isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, or tranylcypromine. Concerta may cause new or worsening psychosis (unusual thoughts or behavior), especially if you have a history of depression, mental illness, or bipolar disorder. You may have blood circulation problems that can cause numbness, pain, or discoloration in your fingers or toes.
