DoxyPEP for STI Prevention

How It Works, Who It’s For, and What to Know

What Is DoxyPEP?

DoxyPEP, short for doxycycline post-exposure prophylaxis, is a preventive strategy that involves taking a dose of the antibiotic doxycycline after sexual exposure to reduce the risk of certain bacterial sexually transmitted infections (STIs).

DoxyPEP is not a vaccine and does not prevent all STIs. It is a risk-reduction tool recommended for specific populations based on evidence showing reduced rates of some bacterial STIs when used correctly.
