Quick Answer

Doctors prescribe antibiotics to cure chlamydia, most commonly a single dose of azithromycin or a seven-day course of doxycycline. Both are highly effective when taken as directed. Treatment is safe during pregnancy with alternative antibiotics like amoxicillin or erythromycin.

  • Chlamydia is caused by the bacterium Chlamydia trachomatis.
  • Most people with chlamydia have no symptoms, so testing is key.
  • Untreated chlamydia can lead to pelvic inflammatory disease and infertility.
  • Antibiotics cure chlamydia; retesting after treatment is recommended.
  • Partners should be treated to prevent reinfection.
  • Using condoms reduces the risk of getting or spreading chlamydia.

Context Most Pages Skip

Chlamydia is the most commonly reported bacterial sexually transmitted infection in the United States. It spreads through vaginal, anal, or oral sex with an infected partner. Because it often causes no symptoms, many people do not know they have it, which is why routine screening is recommended for sexually active people under 25 and for others at higher risk. The infection is caused by a bacterium, so it responds well to antibiotics. Early treatment not only cures the infection but also prevents serious complications like pelvic inflammatory disease and ectopic pregnancy. Understanding how chlamydia works and how it is treated helps you make informed decisions about testing and care.
