Prolonged nocturnal penile tumescence caused by epinastine.
OBJECTIVE
We report a case of prolonged nocturnal penile tumescence (NPT) caused by the antiallergic agent epinastine.


RESULTS
We measured NPT using Rigiscan-Plus (DacoMed, Minneapolis, MN, USA) with or without the patient having taken epinastine.


CONCLUSIONS
Considering its pharmacological effects on cyclic nucleotides, epinastine may have an effect on erectile function.
