What is chlamydia?

Chlamydial infection is the most frequently reported STI in the U.S. If left untreated, chlamydia can cause pelvic inflammatory disease (PID), ectopic pregnancy, infertility, and chronic pelvic pain due to scarring of fallopian tubes and other tissues inside of the pelvis and upper abdomen. You can get chlamydia by having vaginal, anal, or oral sex with someone who has chlamydia.

Get the Treatment You Need

When taken properly, certain antibiotics will cure chlamydia and decrease your chances of having complications later on. Both the patient and their sex partners need to take all of the antibiotic tablets to prevent reinfection and infection of other partners. You should be tested again about three months after you are treated, even if your sex partner(s) was treated.
