1Contraindicated for pregnant patients.
2Every effort should be made to use a recommended regimen. Test-of-cure follow-up with a nucleic acid amplification test (NAAT) 4 weeks after completion of therapy is recommended in pregnancy.
4For persons weighing >150 kg, use 1 gm IM ceftriaxone x 1 dose instead.
5Oral cephalosporins give lower and less-sustained bactericidal levels than ceftriaxone. Cefixime should only be used when ceftriaxone is not available.
6Test of cure by culture or NAAT is recommended 14 days after treatment of pharyngeal GC.
7If parenteral therapy is selected initially, discontinue 24
ā48 hours after patient improves clinically and continue with either IM or oral therapy for a total of 14 days.
8Other parenteral third-generation cephalosporin (e.g. cefotaxime or ceftizoxime) could be substituted for ceftriaxone.
9If allergy to cephalosporins, can consider fluoroquinolones/azithromycin for PID treatment if community prevalence and individual risk of GC is low, and follow-up is assured. Obtain NAAT testing and GC culture before using fluoroquinolone/azithromycin treatment.
10If patient lives in community with high GC prevalence, or has risk factors (e.g. age <25 years, new partner, partner with concurrent sex partners, or sex partner with a STI), consider empiric treatment for GC.
11Extend doxycycline course to 21 days to cover LGV if perianal or mucosal ulcers, bloody rectal discharge, or tenesmus and rectal CT positive. If perianal or mucosal ulcers present, consider treating for HSV as well.
12Because this regimen has not been rigorously validated, consider a test of cure with CT NAAT four weeks after treatment.
14Safety in pregnancy has not been established, avoid during pregnancy. When using tinidazole, breastfeeding should be deferred for 72 hours after 2 g dose.
15Sprinkle oral granules on applesauce/yogurt/pudding before ingestion. Glass of water after dose can aid in swallowing. FDA-approved for treatment of trichomonas after the release of the CDCās 2021 STI Treatment Guidelines.
16Clindamycin ovules may weaken latex or rubber products (such as condoms and diaphragms). Use of such products within 72 hours following use of clindamycin ovules is not recommended.
17Gonorrhea should be ruled out prior to starting a fluroquinolone-based regimen.
18May weaken condoms and vaginal diaphragms. Advise patients to follow package insert directions carefully. Imiquimod users wash area 6
āā10 hours after application. Sinecatechin ointment should not be washed off.
19Limited human data on imiquimod use in pregnancy; animal data suggest low risk.
20Podophyllin resin is an alternative rather than recommended regimen due to reports of severe toxicity. The safety of podophyllin in pregnancy has not been established.
21The use of a cryoprobe in the vagina is not advised due to risk of vaginal perforation and fistula formation.
22Treatment can be extended if healing is incomplete after 10 days of antiviral therapy.
23Consider high dose valacyclovir (1 gm daily) or acyclovir in people who have frequent recurrences (i.e., 10 or more episodes annually).
24Famciclovir is somewhat less effective for suppression of viral shedding.
25If concern for resistance based on persistent HSV lesions, obtain a viral isolate for sensitivity testing. Consultation with an infectious disease expert is recommended.
26Benzathine penicillin G is available in only one long-acting formulation, BicillinĀ® L-A (the trade name), which contains only benzathine penicillin G. Other combination products, such as BicillinĀ® C-R, contain both long- and short-acting penicillins and are not effective for treating syphilis.
27Alternative regimens should be used only for penicillin-allergic patients. If compliance or follow-up cannot be ensured, the patient should be desensitized and treated with benzathine penicillin.
28In non-pregnant patients, pharmacologic considerations reveal an interval of 7
ā9 days is ideal.
29Some specialists recommend 2.4 million units of benzathine penicillin G once weekly for 1 to 3 weeks immediately after completion of neurosyphilis treatment.
30Pregnant patients allergic to penicillin should be desensitized and treated with penicillin. There are no alternatives.
31For early syphilis, many experts give a 2nd dose of benzathine penicillin G 2.4 million units IM one week after the initial dose.
32The optimal treatment interval in pregnancy is 7 days. If treatment occurs outside of 6
āā8-day intervals, the full treatment course should be restarted.
