Most patients with chlamydia are prescribed doxycycline. Patients who cannot tolerate this type of antibiotic are given azithromycin instead. The two medicines are both used to treat uncomplicated urogenital chlamydia, but they work in different ways. 

  • Doxycycline — one capsule taken twice a day, over seven days 
  • Azithromycin — a 1g dose, followed by two 500mg tablets over two days

If your doctor or pharmacist thinks that it is highly likely you have chlamydia, for example if you’ve had unprotected sex with someone who has the infection, then they will start you on a course of antibiotics before your test results come back.
