What antibiotics are used to treat chlamydia and gonorrhea?

Official Answer


From the 2015 Sexually Transmitted Disease (STD) guidelines, the CDC recommends treatment for a gonorrhea-chlamydia coinfection with azithromycin (Zithromax) 1 gram given orally in a single dose, plus ceftriaxone (Rocephin) 250 mg given intramuscularly as first-line therapy.

As dual therapy, ceftriaxone and azithromycin should be administered together on the same day, preferably at the same time, and under direct observation by a health care provider.

Co-infection of gonorrhea with chlamydia can be found commonly in the community setting.
