Executive summary

  • Test with NAAT (self-taken vulvovaginal swab often preferred; first-catch urine for men).
  • First-line: doxycycline 100 mg BD for 7 days (avoid in pregnancy/breastfeeding).
  • Assess for PID/epididymo-orchitis; arrange partner notification and STI screen per local pathway.

Key steps (primary care workflow)

  • Confirm pregnancy status where relevant; offer gonorrhoea testing and HIV/syphilis based on risk.
  • Advise no sex until treatment completed and partners treated; consider retest for reinfection (~3 months) per local policy.

When to refer

  • Immediate if pelvic pain/fever/bleeding suggests PID or if testicular pain/swelling suggests epididymo-orchitis.
  • Sexual health clinic referral is helpful for pregnancy-safe regimens, partner management, and broader STI care.

Frequently asked questions

Do I need a test-of-cure?
Commonly reserved for pregnancy, persistent symptoms, or adherence concerns—follow local sexual health pathways.
Can I be asymptomatic?
Yes—many people have no symptoms, which is why partner notification and retesting for reinfection matter.
