How does this medication work? What will it do for me?
Methylphenidate belongs to the family of medications known as stimulants. It is used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy (uncontrollable need to sleep). It helps to increase attention and decrease restlessness in children and adults who have been diagnosed with ADHD.
Other measures (e.g., psychological, educational, and social therapies) are used along with methylphenidate as part of an overall treatment program for ADHD. This medication also helps to stimulate people with narcolepsy so that they do not fall asleep at inappropriate times.

How should I use this medication?
The dose of methylphenidate needs to be individualized according to the needs of the person taking the medication. The dose is usually started low and increased gradually to the dose that works best for the person.
The usual starting dose for this medication is 5 mg to 10 mg, taken 2 or 3 times daily. Doses above 60 mg daily are not recommended. If symptoms worsen or if side effects occur, contact your doctor for further instruction. In many cases for children, the medication does not need to be continued after puberty.
Take methylphenidate with or shortly after a meal or snack.
If you are taking the sustained release (SR) tablets, swallow the medication whole and do not crush or split the tablets. Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones above, do not change the way that you are taking the medication without consulting your doctor.
It is important to take this medication exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. Avoid taking this medication late in the day, as it may cause difficulty sleeping. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.
Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
