WARNING: Methylphenidate should be given cautiously to emotionally unstable patients such as those with a history of alcohol or drug abuse. These patients may be more likely to unnecessarily increase their doses or take this medication too often. Long-term overuse of this medication may lead to reduced drug effect, drug dependence, and abnormal behavior. Take this medication only by mouth. Serious mental/mood changes (e.g., psychosis) may occur, especially if this drug is abused. If methylphenidate must be stopped, it should be stopped gradually over time. Follow your doctor's instructions on how to gradually lower the dose. In some patients, long-term monitoring may be required after the medication is stopped.

USES: Methylphenidate is used to treat attention disorders (attention deficit hyperactivity disorder, or ADHD) as part of a total treatment plan including psychological, educational and social measures. When used to treat ADHD, patients may find they have increased attention, decreased impulsiveness, and decreased hyperactivity (see also Notes section). This medication is a mild stimulant that works by affecting the levels of chemicals (neurotransmitters) in the nervous system. This medication should not be used to treat simple fatigue symptoms.

OTHER USES: This medication may also be used in patients who have narcolepsy (a disorder of sleep regulation) or be used in combination with other medications to treat certain mood disorders (certain cases of depression).

HOW TO USE: Read the Patient Information Leaflet available from your pharmacist. Consult your doctor or pharmacist if you have any questions. Take this medication by mouth, once daily in the morning, with or without food, or as directed by your doctor. Swallow this medication whole with a full glass of liquid (e.g., water, milk, juice). Do not crush, chew, or break the tablets; doing so can destroy the long action of the drug and may increase side effects. Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same time each day. It may take up to two weeks to notice an improvement while on this drug. Use this medication exactly as prescribed. Dosage is based on your medical condition and response to therapy. Your doctor may instruct you to gradually increase or decrease your dose. Do not increase your dose, use it more frequently or use it for a longer period of time than prescribed because this drug can be habit-forming. Also, if used for a long period of time, do not suddenly stop using this without first consulting your doctor. This medication may cause dependence, especially if it has been used regularly for an extended period of time, or if it has been used in high doses. In such cases, if you suddenly stop this drug, withdrawal reactions may occur. Such reactions can include severe depression and chronic overactivity. Report to your doctor immediately any such reactions. When stopping extended, regular treatment with this drug, gradually reducing the dosage as directed will help prevent withdrawal reactions. Consult your doctor or pharmacist for more details. Though it is very unlikely to occur, this medication can also result in abnormal drug-seeking behavior (addiction/habit-forming). Do not increase your dose, take it more frequently or use it for a longer period of time than prescribed. Properly stop the medication when so directed. This will lessen the chances of becoming addicted. When used for an extended period, this medication may not work as well and may require different dosing. Talk with your doctor if this medication stops working well. Inform your doctor if your condition persists or worsens.
