Warning added to drug

WASHINGTON (AP) -- The Food and Drug Administration on Monday announced changes to the labels for Dexedrine, an amphetamine used to treat attention-deficit hyperactivity disorder and narcolepsy, to warn of possible heart problems it may cause.
There have been reports of sudden death caused by stimulant treatment in children and adolescents with serious heart problems, the FDA said. The new warning labels will reflect that information.
Earlier this month, Dexedrine manufacturer GlaxoSmithKline advised health care professionals of changes to the drug's labeling.
