Syphilis and donovanosis
Do if pregnant
- Medical consult — this is an STI emergency
Do
- Take blood for syphilis serology before starting treatment for accurate baseline (pre-treatment) RPR level
- Give benzathine benzylpenicillin (Bicillin L-A) IM — adult 2,400,000 units/4.6mL (1.8g) (2 x 2.3mL syringes), single dose — to start treatment for syphilis
- If allergy to penicillin — medical consult
- If donovanosis suspected — sexual health consult
- Contact tracing — very important if you suspect new syphilis infection. Get advice from sexual health unit
- Talk about STIs and safer sex
If recent syphilis — often get harmless febrile reaction to treatment (Jarisch-Herxheimer). Starts in 3–4 hours, gets better within 24 hours
- Give paracetamol — adult 1g up to 4 times a day (qid)
Follow-up
- Review at 1 week
- Check test results. If positive — see STI management
- If ulcer not healing and tests negative — medical consult and add recall for 4 week review
- If you suspect donovanosis but tests negative — sexual health consult
Genital herpes
- Herpes simplex virus (HSV) causes genital and oral herpes (cold sores)
- Antiviral treatment reduces risk of spreading infection, duration and severity of symptoms — but doesn't cure
- Lifelong risk of recurrent episodes and shedding of herpes virus
- Infection with both herpes and syphilis possible
Do
- Keep sores clean with normal saline washes
- Give pain relief — can put lidocaine (lignocaine) gel on sores
- If kidney disease — medical consult. May need lower doses of antivirals
First episode
Can be severe. Lasts 2–3 weeks

- Medicines are most helpful if blisters present for 3 days or less
- Give valaciclovir oral — adult 500mg, twice a day (bd) for 5–10 days
- Review at 1 week
- Positive herpes NAAT confirms genital herpes
- Negative herpes NAAT does not exclude genital herpes — ask to return for another swab if sores come back
Recurrent episodes
Usually less severe. Lasts 1 week or less
- Medicines are most helpful if given before or on the first day blisters appear
- Give valaciclovir oral — adult 500mg, twice a day (bd) for 3 days
OR famciclovir oral — adult 1g, twice a day (bd) for 1 day
