Doxy PEP stands for doxycycline post-exposure prophylaxis. It is a prevention strategy that involves taking the antibiotic doxycycline after condomless oral or anal sex to prevent chlamydia, gonorrhea, or syphilis.
Doxy PEP is intended for adult men who have sex with men and transgender women who have sex with men, especially those who have had an STI in the last year. Health care providers may also suggest it to people in this community who have more than one partner.
