Does Chlamydia Go Away on Its Own Without Antibiotics?

No, chlamydia does not go away on its own without antibiotic treatment. This bacterial infection requires prescription antibiotics to be completely eliminated from the body. Without treatment, chlamydia can persist for months or years, potentially causing serious complications. Studies show that untreated chlamydia leads to pelvic inflammatory disease in 10-15% of women, which can result in infertility or ectopic pregnancy. In men, untreated chlamydia may cause epididymitis and testicular inflammation. The infection can also spread to sexual partners during this time. Fortunately, chlamydia responds well to antibiotics like azithromycin or doxycycline, with cure rates exceeding 95% when treatment is completed properly.
