Dear editor,Premature ejaculation(PE)is a common male sexual dysfunction.It occurs in 4%e39%of men across studies in community samples[1].It is impossible to establish accurately the real prevalence of PE because it lacks a widely accepted definition.Furthermore,PE is frequently a self-reported,self-rated complaint,making it difficult to appreciate its real epidemiology.In addition,the fact that in some couples PE is diagnosed based on distress rather than as an objective symptom complicates the matter even further[2].Oral dapoxetine has been recommended as first-choice therapy for PE.When using this drug,side effects were uncommon,dose-dependent,including nausea,diarrhea,headache,and dizziness[1].Although since the early 1930s,many drugs have been used to treat PE such as topical local anesthetics and selective serotonin reuptake inhibitors.
