The Centers for Disease Control and Prevention have finalized guidelines for post-exposure prophylaxis against bacterial sexually transmitted infections, recommending the use of doxycycline within 72 hours of sexual activity for higher-risk groups. This is the first time the antibiotic is being used as prophylaxis against STIs, with studies showing significant reductions in chlamydia and syphilis infections. The guidelines focus on shared decision-making between patients and practitioners, highlighting the importance of access and equitable distribution. Ongoing studies will evaluate the effectiveness of doxy PEP and its impact on antimicrobial resistance. Further research is urged for different populations, such as cisgender women.
