Case reports have documented the utility of sildenafil for sexual dysfunction caused by selective serotonin-reuptake inhibitors (SSRIs) and have suggested its potential utility for women and men with various iatrogenic sexual dysfunctions. This brief review summarizes the psychopharmacology of sildenafil, discusses possible interactions with SSRIs, reviews side effects and risks, highlights the need for concomitant psychological counseling, reviews sildenafil's possible mechanisms of action for iatrogenic sexual dysfunctions, and suggests areas for future research.
