Chlamydia in Pregnancy
Clinical detail
Additional detail checked 2026-10-17 against the linked sources. This check covers the section below; the rest of the module retains its displayed verification status.
Chlamydia can be asymptomatic in pregnancy. The useful clinical pathway includes a sensitive test, a pregnancy-appropriate regimen, a test of cure and prevention of reinfection.
Assessment & interpretation
- Use NAAT on an appropriate vaginal/cervical sample or urine. Ask about symptoms, exposure sites and other STI risks.
- Assess pelvic pain or systemic illness separately rather than assuming uncomplicated cervicitis. Offer testing for gonorrhoea, syphilis and HIV.
Decisions that change management
- CDC’s pregnancy regimen is azithromycin 1 g orally once. The alternative is amoxicillin 500 mg orally three times daily for 7 days.
- Arrange partner evaluation and treatment; recent partners from the preceding 60 days are relevant. Apply local law and service arrangements to partner management.
Follow-up & safety-netting
- In pregnancy, perform a NAAT test of cure at approximately 4 weeks after treatment and retest at 3 months.
- Rescreen in the third trimester when risk persists. Very early NAAT testing can detect residual nonviable organisms.
- Avoid intercourse for 7 days after a single-dose regimen and until partners have been treated; also wait for symptoms to resolve.
Clinical pitfalls
- A positive later test may reflect reinfection from an untreated partner rather than antimicrobial failure.
Admission & discharge
Admission/discharge guidance checked 2026-10-18 against the linked sources. This is a clinical checklist for an individual decision, not an automatic discharge order.
When admission or continued hospital care is needed
- Pelvic/systemic illness, significant pain, fever or a suspected obstetric complication requires assessment for PID, ectopic pregnancy or another cause and admission when indicated.
When clinic, day care or home care may be suitable
- Uncomplicated chlamydia in a stable pregnant patient can usually be treated outside hospital with partner care and follow-up.
Before going home
- Treatment is provided, tolerated or reliably arranged; partner management and pregnancy-specific follow-up are explained.
Discharge medicines and treatment changes
- Use the checked pregnancy regimen and counsel about adherence and sex/partner treatment to prevent reinfection.
Medicine doses — use only when indicated
Use the medicines selected for this patient. Listed alternatives are not instructions to prescribe all of them together. Confirm the actual remaining course, pregnancy/postnatal context and monitoring plan.
For the selected pregnancy-compatible chlamydia regimen.
- Indication: Recommended CDC regimen for chlamydia in pregnancy
- Partner treatment, adherence/retained dose, symptoms; do not test NAAT too early after treatment
Tests, pending results and their reviewer
- Pregnancy: test of cure about 4 weeks after treatment and repeat testing at 3 months; further pregnancy retesting follows risk/programme guidance.
Home care and counselling
- Explain partner notification and avoidance of sex until the required interval/treatment completion and partner treatment are satisfied.
Follow-up: when and what to review
| When | Action / responsible service |
|---|---|
About 4 weeks | Pregnancy test of cure; evaluate persistent symptoms sooner. |
3 months | Retest for reinfection and reassess ongoing risk. |
Return urgently
- Fever, severe pelvic/abdominal pain, fainting or ongoing/worsening symptoms requires assessment.

Treatment
① Immediate stabilization — first minutes
③ First-line treatment & drug regimens
- Recommended CDC regimen for chlamydia in pregnancy

Monitoring
- NAAT test-of-cure 4 wks
- Partners treated; abstain until both complete
Post-treatment care
- Neonatal opthalmia/pneumonia awareness at birth
Diagnosis & assessment
- Haemodynamic instability -> sepsis pathway
