RESUMEN
Priapism is a persistent, usually painful, erection that lasts for more than four hours and occurs without sexual stimulation. The condition develops when blood in the penis becomes trapped and is unable to drain. This condition appears to affect only the corpora cavernosa, while the corpora spongiosum of the glans penis and surrounding urethra remain flaccid. Priapism may be a urologic emergency that is associated with the development of irreversible erectile function problems. Therefore, immediate and aggressive management may be necessary. If the condition is not treated immediately, it can lead to scarring and permanent erectile dysfunction Citalopram is a relatively new selective serotonin reuptake inhibitor [SSRI] that is becoming widely administered for the treatment of depression. Selective serotonin reuptake inhibitors generally are associated with mild adverse sexual side effects; however, more serious reactions may occur. Although selective serotonin reuptake inhibitors [SSRIs] can induce sexual side effects, such as diminished libido, delayed orgasm, anorgasmia, ejaculatory disturbances, and erectile dysfunction, priapism occurs rarely [1]. We present a case report of 45 years old gentleman who presented in A and E of Gloucester Royal Infirmary, Gloucestershire UK, with priapism of 4 days' duration
