General Guidance: Unlike malaria prophylaxis, doxycycline for STI prevention typically does not require extended use after the trip ends. Studies and clinical guidelines suggest that you should continue doxycycline for up to 1–2 days after your last potential exposure (i.e., after the last sexual activity that may have been high-risk). The reason for this is that doxycycline works best when taken immediately after exposure, preventing the bacteria (such as chlamydia or gonorrhea) from establishing infection.
