dexmethylphenidate oral Warnings

Misuse or abuse of dexmethylphenidate may result in serious (possibly fatal) heart and blood pressure problems.

This medication can be habit-forming and should be used cautiously by people who have mental/mood disorders or a history of alcohol/drug abuse. Before taking this medication, tell your doctor if you have abused or been dependent on drugs or alcohol. Do not increase your dose, take it more often, or take it for a longer time or in a different way than prescribed. Doing so may result in a decrease in the effect of this drug, drug dependence, or abnormal thoughts/behavior.

Your doctor may monitor you for a while after the medication is stopped, especially if you have taken this drug for a long time or in high doses. (See also How to Use section.)

dexmethylphenidate oral Uses

Dexmethylphenidate is used as part of a treatment program (including psychological, educational, and social measures) to treat attention deficit hyperactivity disorder - ADHD. It can help increase your ability to pay attention, stay focused on an activity, and control behavior problems. It may also help you to organize your tasks and improve listening skills. Dexmethylphenidate is a mild stimulant that is thought to work by changing the amounts of certain natural substances in the brain.

OTHER USES: This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.

This drug may also be used to treat a certain sleep disorder (narcolepsy).

How to use dexmethylphenidate oral

Read the Medication Guide provided by your pharmacist before you start taking dexmethylphenidate and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth as directed by your doctor, usually once daily in the morning, with or without food. Taking this medication late in the day may cause trouble sleeping (insomnia).

The dosage is based on your medical condition and response to treatment. Your doctor may direct you to gradually increase or decrease your dose. Also, if you have used it for a long time, do not suddenly stop using this drug without consulting your doctor.

Do not break, crush, or chew this medication. Doing so can release all of the drug at once, increasing the risk of side effects. Swallow the capsules whole. If you have trouble swallowing the capsule, you may open the capsule and carefully sprinkle its contents on a spoonful of cool applesauce. Swallow all of the mixture right away without chewing it. Then drink a glass of cool liquid to make sure you have swallowed all of the dose. Do not prepare the mixture ahead of time.

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.

Take this medication regularly 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.

When this medication is used for a long time, it may not work as well. Talk with your doctor if this medication stops working well.

Along with its benefits, this medication may rarely cause abnormal drug-seeking behavior (addiction). This risk may be increased if you have abused alcohol or drugs in the past. Take this medication exactly as prescribed to lessen the risk of addiction.

Tell your doctor if your condition does not improve or if it worsens.

If a painful or prolonged erection occurs, stop using this drug and get medical help right away, or permanent problems could occur. Ask your doctor or pharmacist for more details.
