What is Ritalin?
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.
Before taking this medicine
Do not use Ritalin if you have used an MAO inhibitor in the past 14 days. A dangerous drug interaction could occur. MAO inhibitors include isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, tranylcypromine, and others.
You may not be able to use Ritalin if you are allergic to methylphenidate, or if you have:
a personal or family history of tics (muscle twitches) or Tourette’s syndrome; or
severe anxiety, tension, or agitation (stimulant medicine can make these symptoms worse).
Stimulants have caused stroke, heart attack, and sudden death in certain people. Tell your doctor if you have:
heart problems or a congenital heart defect;
high blood pressure; or
a family history of heart disease or sudden death.
To make sure Ritalin is safe for you, tell your doctor if you or anyone in your family has ever had:
depression, mental illness, bipolar disorder, psychosis, or suicidal thoughts or actions;
motor tics (muscle twitches) or Tourette’s syndrome;
blood circulation problems in the hands or feet;
seizures or epilepsy;
problems with the esophagus, stomach, or intestines;
an abnormal brain wave test (EEG); or
a history of drug or alcohol addiction.

How should I take Ritalin?
Take Ritalin exactly as prescribed by your doctor. Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not take Ritalin in larger or smaller amounts or for longer than recommended.
Your dose needs may change if you switch to a different brand, strength, or form of methylphenidate. Avoid medication errors by using only the form and strength your doctor prescribes.
Ritalin may be habit-forming. Never share this medicine 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. Selling or giving away this medicine is against the law.
Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.

Ritalin tablets and Ritalin SR tablets should be taken at least 30 to 45 minutes before a meal. Extended-release Ritalin LA capsules can be taken with or without food. Follow the directions on your medicine label.
Do not crush, chew, or break a sustained-release tablet. Swallow the tablet whole. Breaking the tablet may cause too much of the drug to be released at one time.
To make swallowing easier, you may open the Ritalin LA capsule and sprinkle the medicine into a spoonful of pudding or applesauce. Swallow right away without chewing. Do not save the mixture for later use.
While using Ritalin, your doctor will need to check your progress at regular visits. Tell any doctor who treats you that you are using this medicine.
If you need surgery, tell the surgeon ahead of time that you are using Ritalin. You may need to stop using the medicine for a short time.
Store at room temperature away from moisture and heat.
Keep track of your medicine. Methylphenidate is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.
What happens if I miss a dose?
Take the missed dose as soon as you remember. Skip the missed dose if it is later than 6:00 p.m. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call 115. An overdose of methylphenidate could be fatal.
What should I avoid while taking Ritalin?
