2021 CDC guidelines on sexually transmitted infections

If ceftriaxone is unavailable, there are 2 alternative regimens: gentamicin 240 mg IM in a single dose, plus azithromycin 2 g po in a single dose; or cefixime 800 mg po in a single dose.¹ However, these alternatives are not recommended for gonococcal infection of the pharynx, for which ceftriaxone should be used.

Counsel those treated for gonorrhea to avoid sexual activity for 7 days after treatment and until all sex partners have been treated. Because of the high rates of asymptomatic infections, tell patients to refer those with whom they have had sexual contact during the previous 60 days for evaluation, testing, and presumptive treatment.

Following treatment with the recommended dose of ceftriaxone, performing a test of cure is not recommended, with 1 exception: those with confirmed pharyngeal infection should be tested to confirm treatment success 7 to 14 days after being treated. However, all those treated for gonorrhea should be seen again in 3 months and retested to rule out reinfection, regardless of whether they think their sex partners have been adequately treated.

Chlamydia

The recommended first-line therapy for chlamydia is now doxycycline 100 mg twice a day for 7 days, which has proven to be superior to azithromycin (which was recommended as first-line therapy in 2015) for urogenital chlamydia in men and anal chlamydia in both men and women.^1,2 Alternatives to doxycycline include azithromycin 1 g po as a single dose or levofloxacin 500 mg po once a day for 7 days.¹ No test of cure is recommended; but as with gonorrhea, retesting at 3 months is recommended because of the risk for re-infection.

No test of cure is needed following gonococcal infection treated with a recommended dose of ceftriaxone, except in those with confirmed pharyngeal infection.

Instruct patients treated for chlamydia to avoid sexual intercourse for 7 days after therapy is initiated or until symptoms, if present, have resolved. To reduce the chances of reinfection, advise treated individuals to abstain from sexual intercourse until all of their sex partners have been treated.
