[Quetiapine in the treatment of the Gilles de la Tourette syndrome. A case study].

In this article we describe the clinical response of an 8-year-old boy with the Gilles de la Tourette syndrome (GTS) when treated with quetiapine. Upon admission for observation he received a trial course of quetiapine, to which he responded favourably. We searched the Medline and Psycinfo databases for information about the recommended dose of quetiapine for children with GTS. From the 12 case-studies and one open-label trial that we found, we conclude that the maximum dose of quetiapine for children with GTS is 200 mg. Data concerning the safety of quetiapine when administered to children are limited and contradictory.
