Read the Medication Guide provided by your pharmacist before you start using dexmethylphenidate and each time you get a refill. If you have any questions, consult your doctor or pharmacist. Take this medication by mouth with or without food, usually once daily as soon as you wake up in the morning or as directed by your doctor. Taking this medication late in the day may cause trouble sleeping (insomnia). The dosage is based on your medical condition and response to therapy. Your doctor may adjust your dose to find the dose that is best for you. The total daily dose is usually 20 milligrams or less. Follow your doctor's instructions carefully. Do not crush or chew the capsules. Swallow the medication whole. If you have difficulty swallowing this medication whole, the capsule may be carefully opened and the contents sprinkled on a spoonful of applesauce. Immediately after mixing, swallow the mixture without chewing. Chewing the mixture may destroy the long action of the drug and may increase the risk of side effects. Do not mix and store for future use. Methylphenidate and dexmethylphenidate are different medications and do not provide the same amount of medicine. Do not switch between products unless your doctor tells you to. Use this medication regularly and exactly as prescribed in order to get the most benefit from it. To help you remember, take it at the same time each day. 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 as depression, suicidal thoughts, or other mental/mood changes) 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 time than prescribed. Properly stop the medication when so directed. This will lessen the chances of becoming addicted. Inform your doctor if your condition persists or worsens. Your doctor may recommend drug holidays when your medication is stopped temporarily so that behavior can be re-evaluated.
