The objective of this study was to identify the use of phosphodiesterase type 5 inhibitors among university students from the city of Sao Paulo (SP) in Brazil. Male students (n=350) replied to a questionnaire about diagnosis of erectile dysfunction, the frequency and reason for the use of phosphodiesterase type 5 inhibitors, the specific medication used, whether their use was accompanied by a medical prescription and any reported side-effects. The results shows that a total of 53 (14.7%) students had already used this kind of medication without a prescription or medical diagnosis for erectile dysfunction, of which 53% reported using sildenafil, 37% tadalafil and 10% vardenafil. The main adverse side-effects reported were headache (23%) and flushing (10%) and the main reasons for using the inhibitor were curiosity (70%) and erectile improvement (12%).
