Doxycycline Post-Exposure Prophylaxis (Doxy-PEP) is a method of preventing sexually transmitted infections (STIs) such as syphilis, chlamydia, and gonorrhea by taking doxycycline after sexual activity.
By taking it within 72 hours of sexual activity, it has been reported to reduce the risk of infection by:
・Syphilis: approximately 87%
・Chlamydia: approximately 88%
・Gonorrhea: approximately 55%
Doxy-PEP is not a drug that prevents HIV. If there is a risk of HIV infection, please consider combining it with PEP.
Recommended for:
・Those who had sex without a condom
・Those concerned about the risk of STIs
・Those who do not know their partner's infection status
・Those who want to prevent STIs in addition to PEP
Since the preventive effect decreases over time, we recommend taking it as soon as possible after sexual activity (preferably within 24 hours, and no later than 72 hours).
