Children are, no more than adults, stricken by psychiatric disorders. Some of them are in dire need of pharmacological treatment. Without such therapy, a certain number of children would be condemned to suffer consequences which could be brief, but also long termed. Because of this, it is of utmost importance to know which medication is being used in paediatric population and which ones are effective and safe for use in children. This is important because there is a general lacking in the number of studies of applied use of psychiatric medication in children, in comparison to those conduced on adults. I have conducted a study about prescribing medication to adolescents psychiatrically treated on the Ward for adolescent psychiatry in the Clinical hospital centre Rijeka, during the period from 1st of May 2014 to 1st of May 2015. All adolescents treated on the Ward in the mentioned period, ages 12-15, were comprised with this study. Data was analysed by examining medical documentation. With analysis, it was established that 162 (71%) patients were treated with psychiatric medication. Psychotic disorder as a first diagnosis (17,18%), was the most diagnosed disorder. Most frequently prescribed medication were sertraline, risperidone and alprazolam. When examining the modality of therapy of patients which are treated with medication, most of them are treated with politherapy. Data gathered with this study showed no divergence from existing guidelines. Because studies in this field are scarce, further study is required and encouraged. )
