Other Comments

Drug treatment is not indicated in all cases of attention deficit disorder with hyperactivity and should be considered only in light of the complete history and evaluation of the child. The decision to prescribe amphetamines should depend on the physician's assessment of the chronicity and severity of the child's symptoms and their appropriateness for his/her age. Prescription should not depend solely on the presence of one or more of the behavioral characteristics. Methylphenidate should be used as part of a comprehensive treatment program.

Where possible, drug administration should be interrupted occasionally to determine if there is a recurrence of behavioral symptoms sufficient to require continued therapy.

If aggravation of symptoms or adverse effects are noted, dosage reduction or discontinuation may be indicated.

The transdermal patch should be placed on a different site each day, typically on the opposite hip.

Extended release formulations of methylphenidate should be swallowed whole and not crushed or chewed. It should be noted that Concerta tablets remain intact and exit the gastrointestinal tract as an empty shell.

Patients should avoid alcohol during treatment.
