ABSTRACT

The introduction of long-acting injectable atypical antipsychotics has ensured adherence to treatment in patients with low awareness of the disorder, with an acceptable rate of side effects. In the case of long acting olanzapine injection in particular, has particular relevance the existence of a special side-effect called post-injection syndrome. This rare side effect consisting in the presence of symptoms of olanzapine overdose after intramuscular administration of medication has led to restrictions on the use of the drug and the need for patient observation for three hours after each injection. We report a case of postinjection syndrome, to our knowledge, the first in Spain since the commercialization of Zypadhera. As in most cases described in the literature have symptoms of overdosage of olanzapine (dysarthria, sedation, fatigue, etc.) that are selflimiting without any therapeutic measure and are accompanied by supratherapeutic plasma levels of olanzapine.

ABSTRACT

La introducción de los antipsicóticos atípicos de liberación retardada ha permitido asegurar la adherencia al tratamiento en aquellos pacientes con baja conciencia de trastorno, con una tasa aceptable de efectos secundarios. En el caso de la olanzapina de liberación retardada en concreto, tiene especial relevancia la existencia del llamado Síndrome post-inyección. Este efecto secundario poco común consistente en la presencia de síntomas de sobredosis de olanzapina tras la administración intramuscular de la medicación ha supuesto restricción del uso del medicamento y la necesidad de observación del paciente durante tres horas después de cada inyección. Se presenta un caso de Síndrome post-inyección, a nuestro conocimiento, el primero en España desde la comercialización de Zypadhera. Al igual que en la mayoría de casos descritos en la bibliografía el paciente presenta síntomas de sobredosificación de olanzapina (disartria, sedación, astenia, etc.) que se auto limitan sin medida terapéutica alguna y se acompañan de niveles plasmáticos supraterapéuticos de olanzapina(AU)
