Sexual risk behaviors among men who have sex with men using erectile dysfunction medications.
This study examined relationships between use of the phosphodiesterase type-5 (PDE-5) inhibitors (erectile dysfunction medications) sildenafil (Viagra), Pfizer, New York, NY), tadalafil (Cialis), Eli Lily, Indianapolis, IN), and/or vardenafil (Levitra), Bayer, Berlin, Germany), substance use, perceptions of risk, and sexual behavior in men who have sex with men (MSM). MSM (N = 342) attending a gay pride festival completed a brief survey assessing sexual behavior, risk perceptions, and substance use, including the use and the source of PDE-5 inhibitors. More than a quarter of the sample (26.3%, n = 89) reported having ever used a PDE-5 inhibitor. Those reporting use of PDE-5 inhibitors had higher rates of sexual risk behaviors and differed in their assessment of the risk of HIV transmission for unprotected anal sex. Users who received PDE-5 inhibitors from their doctors did not report sexual behaviors that differed significantly from those who received PDE-5 inhibitors from nonphysician sources. In a sequential logistic regression analysis, recent PDE-5 inhibitor use was associated with unprotected anal sex after accounting for the influence of age, education, ethnic identity, and substance use. Many MSM users of erectile dysfunction drugs report behaviors that may place their and others' health at risk. Interventions to reduce risk among MSM PDE-5 inhibitor users should be explored.
