Drug Information: Methylphenidate
URL of this page: http://www.nlm.nih.gov/medlineplus/druginfo/medmaster/a682188.html
(meth il fen' i date)IMPORTANT WARNING:
| Methylphenidate can be habit-forming. Do not take a larger dose, take it more often, take it for a longer time, or take it in a different way than prescribed by your doctor. If you take too much methylphenidate, you may find that the medication no longer controls your symptoms, you may feel a need to take large amounts of the medication, and you may experience unusual changes in your behavior. Tell your doctor if you drink or have ever drunk large amounts of alcohol, use or have ever used street drugs, or have overused prescription medications.Do not stop taking methylphenidate without talking to your doctor, especially if you have overused the medication. Your doctor will probably decrease your dose gradually and monitor you carefully during this time. You may develop severe depression if you suddenly stop taking methylphenidate after overusing it.Your doctor or pharmacist will give you the manufacturer’s patient information sheet (Medication Guide) when you begin treatment with methylphenidate and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/cder) or the manufacturer's website to obtain the Medication Guide. |
Why is this medication prescribed?
Methylphenidate is used as part of a treatment program for attention deficit hyperactivity disorder (ADHD; more difficulty focusing, controlling actions, and remaining still or quiet than other people who are the same age). Methylphenidate (Ritalin, Ritalin SR, Methylin, Methylin ER) is also used to treat narcolepsy (a sleep disorder that causes excessive daytime sleepiness and sudden attacks of sleep). Methylphenidate is in a class of medications called central nervous system (CNS) stimulants. It works by changing the amounts of certain natural substances in the brain.
How should this medicine be used?
Methylphenidate comes as an immediate-release tablet, a chewable tablet, a solution (liquid); an intermediate-acting (extended-release) tablet; a long-acting (extended-release) capsule, and a long-acting (extended release) tablet. The long-acting tablet and capsules supply some medication right away and release the remaining amount as a steady dose of medication over a long time.All of these forms of methylphenidate are taken by mouth. The regular tablets (Ritalin, Methylin), chewable tablets (Methylin), and solution (Methylin) are usually taken 2 to 3 times a day, preferably 35-40 minutes before meals. The last dose should be taken at least several hours before bedtime. The intermediate-acting extended release tablets (Ritalin SR, Metadate ER, Methylin ER) are usually taken once a day in the morning with or without food. The long-acting extended release capsule (Metadate CD) is usually taken once a day before breakfast; the long-acting extended-release tablet (Concerta) and capsule (Ritalin LA) are usually taken once a day in the morning with or without food.
Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take methylphenidate exactly as directed.
You should thoroughly chew the chewable tablets and then drink a full glass (at least 8 ounces) of water or other liquid. If you take the chewable tablet without enough liquid, the tablet may swell and block your throat and may cause you to choke. If you have chest pain, vomiting, or trouble swallowing or breathing after taking the chewable tablet, you should call your doctor or get emergency medical treatment immediately.
Swallow the intermediate acting and long-acting extended-release tablets and capsules whole; do not split, chew, or crush them.However, if you cannot swallow the long-acting capsules (Metadate CD, Ritalin LA), you may carefully open the capsules and sprinkle the entire contents on a tablespoon of cool or room temperature applesauce. Swallow (without chewing) this mixture immediately after preparation and then drink a glass of water to make sure you have swallowed all of the medicine. Do not store the mixture for future use.
Your doctor may start you on a low dose of methylphenidate and gradually increase your dose, not more often than once every week.
Your condition should improve during your treatment. Call your doctor if your symptoms worsen at any time during your treatment or do not improve after one month.
Your doctor may tell you to stop taking methylphenidate from time to time to see if the medication is still needed. Follow these directions carefully.
Other uses for this medicine
Methylphenidate should not be used to treat depression or excessive tiredness that is not caused by narcolepsy.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
What special precautions should I follow?
Before taking methylphenidate,
- tell your doctor and pharmacist if you are allergic to methylphenidate or any other medications.
- tell your doctor if you are taking monoamine oxidase (MAO) inhibitors, including isocarboxazid (Marplan), phenelzine (Nardil), selegiline (Eldepryl), and tranylcypromine (Parnate), or have stopped taking them during the past 14 days. Your doctor will probably tell you not to take methylphenidate until at least 14 days have passed since you last took an MAO inhibitor.
- tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking. Be sure to mention any of the following: antidepressants ('mood elevators'); anticoagulants ('blood thinners') such as warfarin (Coumadin); clonidine (Catapres); guanabenz; medications for seizures such as phenobarbital, phenytoin (Dilantin), and primidone (Mysoline); and methyldopa (Aldomet). If you are taking Ritalin LA, also tell your doctor if you take antacids.
- tell your doctor if you or anyone in your family has or has ever had Tourette's syndrome (a condition characterized by the need to perform repeated motions or to repeat sounds or words), facial or motor tics (repeated uncontrollable movements), or verbal tics (repetition of sounds or words that is hard to control), Also tell your doctor if you have glaucoma, or feelings of anxiety, tension, or agitation. Your doctor will probably tell you not to take methylphenidate.
- tell your doctor if anyone in your family has or has ever had an irregular heartbeat or has died suddenly. Also tell your doctor if you have recently had a heart attack and if you have or have ever had a heart defect, high blood pressure, an irregular heartbeat, heart or blood vessel disease, or other heart problems. Your doctor will probably examine you to see if your heart and blood vessels are healthy. Your doctor may tell you not to take methylphenidate if you have a heart condition or if there is a high risk that you may develop a heart condition.
- also tell your doctor if you have or ever have had seizures, or mental illness. If you are taking the chewable tablets, tell your doctor if you have trouble swallowing or if you have phenylketonuria (PKU, a disease in which you must avoid certain foods). If you are taking the long-acting extended-release tablet (Concerta), tell your doctor if you have a a narrowing or blockage of your digestive system.
- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking methylphenidate, call your doctor.
- if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking methylphenidate.
- you should know that methylphenidate should be used as part of a total treatment program for ADHD, which may include counseling and special education. Make sure to follow all of your doctor's and/or therapist's instructions.
What should I do if I forget a dose?
Take the missed dose as soon as you remember it and take any remaining doses for that day at evenly spaced intervals, but do not take a dose at or near bedtime. However, if you remember a missed dose when it is almost time for your next scheduled dose, skip the missed dose. Do not take a double dose to make up for a missed one.

What other information should I know?
If you are taking methylphenidate long-acting tablets (Concerta), you may notice something that looks like a tablet in your stool. This is just the empty tablet shell, and this does not mean that you did not get your complete dose of medication.
Keep all appointments with your doctor and the laboratory. Your doctor may order certain lab tests to check your response to methylphenidate.
Do not let anyone else take your medication. This prescription is not refillable. Be sure to schedule appointments with your doctor on a regular basis so that you do not run out of medication.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
