"CDC Issues New Guidelines for Doxycycline Use"

The CDC has issued new guidelines recommending the use of doxycycline postexposure prophylaxis (doxy PEP) to prevent bacterial sexually transmitted infections (STIs) such as syphilis, chlamydia, and gonorrhea in gay, bisexual, and other men who have sex with men (MSM) and transgender women (TGW) who have had an STI in the past 12 months. The guidelines suggest a 200 mg dose of doxycycline within 72 hours after sex, integrated into a comprehensive sexual health approach. The recommendations are based on studies showing significant reductions in STI incidence with doxy PEP use.
