Doxycycline for STI Prep

I heard rumblings about doxycycline for sort of STI prep. Can you talk me where are we at with that? How should we be thinking about that? Is that something that is commonly used? Sure. When I was in Philadelphia, there was an arm of the Ipergae study to look at reducing the cases of syphilis and chlamydia. And what they noticed is that it actually decreased syphilis cases and chlam Lydia cases. It's cis men or trans females to think about when we're talking about doxyPrep.
