Abstract
Methylphenidate hydrochloride (Ritalin) is a drug which is widely used in the treatment of minimal cerebral dysfunction and narcolepsy. In addition, it has been used parenterally by physicians in several different contexts and abused parenterally in a fashion similar to amphetamines. A psychiatric patient given 40 mg of methylphenidate intravenously developed a severe dyskinetic reaction. Similar dyskinesias have been reported in rare instances in patients who have taken oral methylphenidate, but never previously in a patient who was given the drug intravenously. Some implications of this unique occurrence are discussed.Keywords
