| Research Abstract |
Paroxetine, a selective serotonin reuptake inhibitor (SSRI), has now become the first-line treatment for depression and anxiety disorder. However, discontinuation syndrome following abrupt withdrawal or dose reduction of SSRIs has been recently documented. There are no studies with regard to assess the relation of SSRI discontinuation syndrome and gene polymorphisms. In this study, we investigated the effect of the serotonin-related genetic polymorphisms on the occurrence of paroxetine discontinuation syndrome. In conclusion, the abrupt stoppage of medication is a major risk factor for the occurrence of paroxetine discontinuation syndrome. In addition, the C(-1019)G polymorphism of the 5-HT1A receptor gene may be related to the occurrence of paroxetine discontinuation syndrome.
