Ritalin (methylphenidate) is a central nervous system stimulant. It affects chemicals in the brain and nerves that contribute to hyperactivity and impulse control.
Ritalin is used to treat attention deficit disorder (ADD), attention deficit hyperactivity disorder (ADHD), and narcolepsy.
Ritalin may also be used for purposes not listed in this medication guide.
You should not use Ritalin 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 Ritalin if you have used an MAO inhibitor in the past 14 days, such as isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, or tranylcypromine.
Methylphenidate 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.
Call your doctor right away if you have: signs of heart problems – chest pain, feeling light-headed or short of breath; signs of psychosis – paranoia, aggression, new behavior problems, seeing or hearing things that are not real; signs of circulation problems – unexplained wounds on your fingers or toes.
