Hospitalize when pregnant, acute abdomen cannot be ruled out, tubo-ovarian abscess, severe illness, or when there is no
substantial improvement within 3 days of initiation of oral treatment.
Recommend abstinence from intercourse until 7 days after treatment is initiated
•
Patients should be re-evaluated if symptoms persist or recur after completion of therapy
•
Partners should be referred for evaluation and treatment if sexual contact within the preceding 60 days and should be treated
•
empirically after collecting specimens, even if asymptomatic
Ciprofloxacin contraindicated for pregnant and lactating women and persons <18 years
•
Safety of Azithromycin in pregnant and lactating women is not established, but it is commonly used

Special Cases
STD Pharyngitis
Recommend treatment for both gonococcal and chlamydial infections
Treatment failures should be evaluated by culture and sensitivities
STD Conjunctivitis
Consider gonococcal if history of recent STD
Treat with Ceftriaxone 1g IM x1 dose and saline lavage infected eye.
Disseminated Gonococcal infection
Treat presumptively for concurrent chlamydia unless testing excludes this diagnosis
Treat with Ceftriaxone 1g IM/IV q24 x 1-2 days then Cefixime 400mg po bid or Ciprofloxacin 500mg po bid to complete a
week.
Consider hospitalization if
• Diagnosis is uncertain
• Patient is not deemed reliable to comply with therapy
• Clinical evidence of myocarditis or meningitis
Painful testicle
Treatment of epididymitis most likely caused by gonorrhea or chlamydia
Ceftriaxone 250mg IM x1 and Doxycycline 100mg po bid x 10d or
Ofloxacin 300mg po bid x 10d
Scrotal elevation with jock strap
Analgesics
Followup
Failure to improve within 3 days requires more extensive workup

(vaccine currently being tested)
Genital Warts (Condyloma accuminatum)
Human Papilloma Virus
Treatment Followup

Genital Ulcer Disease
(vaccine currently being tested)
Herpes
Type Treatment
Acyclovir 200mg po 5x day or 400mg po tid x 7-10 days or
Primary
Famciclovir 250mg po tid x 7-10d or
Valacyclovir 1g po bid x 7-10d
Topical therapy substantially less effective and not recommended
Treatment may be extended if healing is incomplete after 10d
Acyclovir 200mg po 5x day or 400mg po tid or 800mg po bid x 5d or
Recurrent
Famciclovir 125mg po bid x 5d or
Valacyclovir 500mg po bid or 1 g po qd x 5d
Have drug at home and begin at first symptom
Acyclovir 400mg po bid x 1 year or
Suppressive Therapy
Documented safe & efficacious up to 6 years
After more than 6 recurrences in 1 year
Famciclovir 250mg po bid x 1 year or
Valacyclovir 500mg po qd or 1 g po qd x 1 year
For more than 10 recurrences / year, 1000mg po qd is more effective
Discuss discontinuing prophylaxis after one year because frequency of recurrences decreases
over time
Suppressive therapy reduces but does not eliminate asymptomatic viral shedding
Syphilis – Treponema pallidum
See bacterial STDs
Chancroid - Haemophilus ducreyi
Treatment
Azithromycin 1g po x 1 or
Ceftriaxone 250 mg IM x 1 or

Treatment Followup
Doxycycline 100mg po bid x 21 d or Follow clinically until all signs and symptoms have resolved
Erythromycin base 500 mg po qid x 21 d Partners should be examined and tested for urethral or cervical
