Chlamydia treatment involves taking an antibiotic. The choice of antibiotic and the duration of the antibiotic course depends on the severity of infection and whether a person has any particular allergies to antibiotics. In uncomplicated or mild infections, the antibiotic course is usually quite brief. A doctor or sexual health clinic can arrange assessment and treatment for Chlamydia if necessary. If symptoms do not get better after taking an antibiotic, or of they go away but then return, it is very important to get reassessed and retested. It is generally recommended to get retested 3 months following treatment, as reinfection is quite common.
