Precautions
It is very important that your doctor check your or your child's progress at regular visits to make sure the dose is right and the medicine is helping you. Your doctor might need to check your blood, heart, and blood pressure for any unwanted effects.
You or your child should not use this medicine if you have used a medicine for depression called a monoamine oxidase inhibitor (MAOI) in the past 14 days. Some examples of MAOI are isocarboxazid (Marplan®), phenelzine (Nardil®), selegiline (Eldepryl®, Zelapar®), or tranylcypromine (Parnate®).
Do not take other medicines unless they have been discussed with your doctor. This especially includes nonprescription medicines, such as aspirin, and medicines for appetite control, asthma, colds, cough, hay fever, allergies, or sinus problems.
This medicine may cause some people to have vision changes or to become drowsy, dizzy, or less alert than they are normally. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy, not alert, or not able to see well.
Dexmethylphenidate may cause serious heart or blood vessel problems. This may be more likely to occur in patients who have a family history of heart disease. Check with your doctor right away if you have chest pain, shortness of breath, or fainting while taking this medicine.
Tell your doctor right away if you or your family notice any unusual changes in behavior, such as an increase in aggression, hostility, agitation, irritability, or suicidal thinking or behavior. Also tell your doctor if you or your child have hallucinations or any unusual thoughts, especially if they are new or getting worse quickly.
This medicine may cause slow growth. If your child is using this medicine, the doctor will need to keep track of your child's height and weight to make sure that your child is growing properly.
