What is methylphenidate?
Methylphenidate is a central nervous system stimulant. It affects chemicals in the brain and nerves that contribute to hyperactivity and impulse control.
Methylphenidate may also be used for purposes not listed in this medication guide.
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 methylphenidate 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.

How should I take methylphenidate?
Take methylphenidate exactly as prescribed by your doctor. Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Methylphenidate 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.

Some brands of methylphenidate should be taken at least 30 minutes before a meal. Extended-release methylphenidate can be taken with or without food. Follow the directions on your medicine label
Do not crush, chew, or break an extended-release tablet. Swallow it whole. Breaking the pill may cause too much of the drug to be released at one time.
To make swallowing easier, you may open the 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.
The chewable tablet must be chewed before you swallow it.
Shake the oral suspension (liquid) well just before you measure a dose. Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.
To take the orally disintegrating tablet (Cotempla XR-ODT):
Keep the tablet in its blister pack until you are ready to take it. Open the package and peel back the foil. Do not push a tablet through the foil or you may damage the tablet.
Use dry hands to remove the tablet and place it in your mouth.
Do not swallow the tablet whole. Allow it to dissolve in your mouth without chewing.
While using methylphenidate, 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 methylphenidate. You may need to stop using the medicine for a short time.

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?
