Doctor I have painful erections

Abstract

IntroductionIschemic (veno-occlusive, low flow) priapism is a painful and persistent penile erection unrelated to sexual desire or stimulation. In some cases, it is an adverse event of antipsychotic medications.Materials and methodsAn Internet search was initiated using the search engines: Direct Sciences; Medline and keywords “Penile erection; priapism; Antipsychotic agents; Side effects” and we illustrated our literature review by a clinical vignette of a man aged 38 years followed for schizophrenia placed under Fluphenazine 125 mg/month from 5 years who consulted us in may 2015 because of priapism and he described painful and prolonged erection episodes evolving for approximately 5 days.DiscussionMedical literature mentions many cases of venous priapism in patients treated by conventional or atypical neuroleptics. About 30% of venous priapisms could be related to drugs of which approximately 50% to neuroleptics. This side effect is related to alpha1-adrenergic blocking properties of these treatments, more or less important depending on the drugs in this class. After emergency treatment, the priapism is the problem of the continued neuroleptic treatment. The substitution of one molecule by another alpha-1 blocking properties to the less marked is recommended.ConclusionThe venous priapism is a uro-andrological emergency requiring prompt treatment to prevent erectile sequelae.Disclosure of interestThe authors have not supplied their declaration of competing interest.
