[Utilization of methylphenidate(Ritalin) in France].
Methylphenidate (Ritalin) is the only psychostimulant approved in France and indicated in attention deficit hyperactivity disorder in children over 6 years. It is under restricted prescription and distribution conditions. As such, it requires a hospital initiated prescription from either a neurology, psychiatry or pediatric specialist and it is covered by the "narcotics" schedule. The French Pharmacovigilance database spontaneous adverse drug reactions reporting, since it was approved in 1995, were analyzed. 21 adverse drug reactions were reported. In 16 cases, methylphenidate was suspected. They were generally non-serious, mild side effects and in most cases promptly resolved. These results do not suggest methylphenidate misuse in France or an overuse in between 1300 and 4000 treated children, to date. Until more information is available concerning the long-term effects of methylphenidate, and in order to limit misuse, inappropriate or overuse, the current prescription and dispensing regulation should be maintained in France, and could well be developed in other countries.
