Abstract:
Consider prescribing doxycycline as prophylaxis for bacterial sexually transmitted infections (STIs) in certain clinical scenarios. New data suggests that a one-time dose of 200 mg doxycycline taken within 72 hours of an unprotected sexual encounter may reduce transmission of syphilis, gonorrhea and chlamydia by a combined two thirds in a high-risk population.
