Racial Differences in Willingness to Use Doxycycline Postexposure Prophylaxis Among Men Who Have Sex With Men in the United States.

We examined racial differences in willingness to use doxycycline postexposure prophylaxis (doxy PEP) to prevent sexually transmitted infections (STIs) among men who have sex with men (MSM) who have not heard of and not used doxy PEP before taking this survey. Most MSM in our study were willing to use doxy PEP. Black, non-Hispanic MSM and Hispanic MSM were more willing to use doxy PEP than White, non-Hispanic MSM. Doxycycline postexposure prophylaxis is an acceptable STI prevention approach among MSM, especially among racial/ethnic minority MSM who are disproportionately affected by bacterial STIs.
