OVERVIEW
Doxy-PEP (Doxycycline Post-Exposure Prophylaxis) is a preventive strategy recommended for people who may be at higher risk of bacterial sexually transmitted infections (STIs).
When taken within 72 hours after condomless sex, doxycycline can help reduce the risk of infections caused by certain bacteria, including chlamydia, syphilis, and gonorrhea.
Doxy-PEP does not prevent against HIV or viral infections. Condom use, regular testing, and open communication with your partner remain the best protection.
Protection when you need it most
Doxy-PEP adds an extra layer of protection after higher-risk exposures.
Timing matters
Take it as soon as possible, but no later than 72 hours after exposure.
A proactive choice
A simple step today for your long-term health and peace of mind.
Part of a balanced sexual health routine
Testing, communication, and prevention work best together.
TREATMENT: HOW DOXY-PEP WORKS
Doxycycline is an antibiotic that can prevent certain bacterial STIs from taking hold in your body when taken after a potential exposure.
HOW TO USE DOXY-PEP
Take one 200 mg dose (usually 2 tablets of 100 mg doxycycline) as soon as possible after condomless sex.
Do not take it later than 72 hours (3 days) after exposure.
Always take with food and a full glass of water to reduce the chance of stomach upset.
Do not use more than one dose for the same exposure.
Continue regular STI testing and safer sex practices.
USE ANTIBIOTICS CAREFULLY
Antibiotics are powerful tools, but they work best when used responsibly.
Why caution is important
Overuse of antibiotics can lead to antimicrobial resistance, making infections harder to treat in the future—for you and for everyone.
Use only when recommended
Doxy-PEP is for people with higher-risk sexual exposures, not for everyday use or as a substitute for condoms.
Follow medical guidance
Your provider will guide you on whether Doxy-PEP is appropriate and how to use it safely.
