What is Concerta?
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 hyperactivity disorder (ADHD) in adults and children 6 years of age and older.
Concerta may also be used for purposes not listed here.
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. Call your doctor right away if you have chest pain or feel lightheaded or short of breath while taking Concerta.
Do not use Concerta if you have used an MAO inhibitor in the past 14 days, such as isocarboxazid, linezolid, phenelzine, rasagiline, selegiline, or tranylcypromine or have used a methylene blue injection.
Concerta may cause new or worsening psychosis (unusual thoughts or behavior), especially if you have a history of depression, mental illness, or bipolar disorder. Call your doctor right away if you have signs of psychosis such as paranoia, aggression, new behavior problems, or seeing or hearing things that are not real.
