Doxycycline PEP for the prevention of bacterial STIs.
The CDC now recommends “doxy PEP” for high-risk individuals. Doxycycline post-exposure prophylaxis (doxy PEP) is a prescription for patients to self-administer 200 mg doxycycline by mouth within 72 hours after anal, oral, or vaginal sex to prevent the transmission of chlamydia, gonorrhea, and syphilis. The CDC defines “high-risk” as men who have sex with men (MSM) and transgender women (TGW) who have been diagnosed with a bacterial STI within the past 12 months. They summarize the findings of the French IPERGAY and ANRS DOXYVAC studies, as well as the US DoxyPEP study, which all show promising reductions in risk ratios or hazard ratios of decreasing bacterial STI transmission on high-risk populations, including those who are taking PrEP for HIV. No significant adverse events related to doxy PEP have been reported.
Conclusion:
Counsel patients at high risk for bacterial STIs regarding the prescription of doxy-PEP for patient self-administration within 72 hours after sex.
