Sammanfattning
Urogenital chlamydia infections, caused by the bacterium Chlamydia trachomatis, is the most common reportable infectious disease in Sweden. In 2009, 37 791 chlamydial infections were reported to the Swedish Institute for Infectious Disease Control. If untreated, chlamydia infections can progress to serious reproductive health problems such as subfertility or infertility in men and women, as well as increased risk of ectopic pregnancy. The chlamydia infection is often asymptomatic and contact tracing is therefore an important tool for identifying infected sex partners. Chlamydia is classified in the Swedish Communicable Diseases Act as a serious disease; consequently, written reporting and contact tracing are compulsory. For uncomplicated genital infections, oral doxycycline, 200 mg as a loading dose, followed by 100 mg once daily for eight days is most commonly prescribed in Sweden. The absorption kinetics of doxycycline may be impaired by concomitant intake of dairy products, polyvalent cations, certain drugs and food items, and these items should therefore be avoided 2 hours before and after doxycycline intake.
