Dexycycline PEP Up To 72 Hours After Unprotected Sex Did Not Prevent STIs In Cisgendered Women, Study Finds

MedPage Today (12/20, Kahn) reports, “Doxycycline postexposure prophylaxis (PEP) up to 72 hours after unprotected sex did not prevent sexually transmitted infections (STIs) in cisgender women, possibly due to poor adherence, a randomized open-label trial showed.” Researchers found “hair sample analysis suggested that 44% of women assigned to doxycycline PEP may have never taken the drug, the authors noted in The New England Journal of Medicine.”
