Read the Medication Guide provided by your pharmacist before you start using methylphenidate and each time you get a refill. If you have any questions, consult your doctor or pharmacist. Take this medication by mouth, usually once daily before or with breakfast, or as directed by your doctor. If the medication upsets your stomach, you may take it with food. Swallow this medication whole. Do not crush or chew the capsule or its contents; doing so can destroy the long action of the drug and may increase side effects. If the capsule cannot be swallowed whole, some brands of this medication allow the capsule to be opened and sprinkled onto applesauce. Ask your pharmacist if your brand may be taken this way. If so, you may sprinkle the contents of a capsule onto a spoonful of applesauce and take immediately. Do not chew the applesauce mixture. Do not save it for later use. Drink a glass of liquid after each dose. 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 this medication is used for a long period of time, do not suddenly stop using this without first consulting your doctor. This medication may cause withdrawal reactions, especially if it has been used regularly for a long time or in high doses. In such cases, withdrawal symptoms (such severe depression and chronic overactivity) may occur if you suddenly stop using this medication. To prevent withdrawal reactions, your doctor may reduce your dose gradually. Consult your doctor or pharmacist for more details, and report any withdrawal reactions immediately. 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.
