What is Doxy-PEP?

A simple step after sex that helps prevent bacterial STIs

Doxy-PEP means taking a single dose of the antibiotic doxycycline within 72 hours after condomless oral, anal or vaginal sex. Studies have shown it can reduce new syphilis and chlamydia infections by about two-thirds or more, and lower gonorrhea infections as well.

The CDC recommends Doxy-PEP for gay and bisexual men and transgender women who have had at least one bacterial STI in the past 12 months. Your provider will talk with you about whether it fits your sex life and health history.

  • Taken only when you need it, after sex rather than every day
  • Works alongside your current plan, including PrEP and condoms
  • Private and judgment-free: your visit happens online, on your schedule

Good to know

Doxy-PEP is one part of sexual health care

  • Doxy-PEP does not prevent HIV, mpox or herpes. Keep using PrEP and condoms as part of your plan.
  • Regular STI testing every 3 to 6 months is still important. Your provider will explain how to stay on schedule.
  • Take doxycycline with a full glass of water and stay upright for 30 minutes afterward.
  • Doxycycline can make your skin more sensitive to the sun, so use sunscreen.

Doxy-PEP is not right for everyone. Your provider will review your medications and health history before prescribing.
