Key Patient Counseling Points. Avoid late evening doses due to resulting insomnia. Swallow the extended-release capsule whole. Do not crush, break, or chew it. If you cannot swallow the extended-release capsule, you may open it and pour the medicine into a small amount of soft food such as pudding, yogurt, or applesauce. Stir this mixture well and swallow it without chewing. Avoid abrupt discontinuation.

Clinical Pearls. Amphetamines have a high potential for abuse, and administration for prolonged periods of time may lead to drug dependence and must be avoided. Misuse of amphetamines may cause sudden death and serious cardiovascular adverse events. Treatment may include drug holidays to assess ongoing need of medication, decrease tolerance, and limit growth suppression. Avoid confusion of multiple different brand names and formulations.
