Clinical review within 2–24 hours

How do I take it?

If we prescribe chlamydia treatment you would take one capsule, twice a day, for seven days.

What are the side effects?

Common side effects of Doxycycline include an allergic rash, nausea, heartburn, vomiting, headache, swelling in your legs and a racing heart. You should also avoid bright sunlight or sunlamps while taking Doxycycline as the medicine can make your skin sensitive in bright light.

For the full information of Doxycycline’s side effects and how to take it, it’s important to read the Patient Information Leaflet that comes with your medicine.

Important safety information

Do not drink alcohol while taking Doxycycline.

It’s important that you tell us which other medicines you’re taking — whether they’re prescription or medicines you’ve bought without a prescription. You must also tell us about any medical conditions you have. We need to know so that we only prescribe Doxycycline if suitable for you. Doxycycline should not be taken at the same time as certain other medicines.

What if I’m pregnant or breastfeeding?

If you are, or could be, pregnant, or if you’re breastfeeding, you should see your GP in person, not use this service. Do not take Doxycycline.

What are my options if I don’t take Doxycycline?

Your GP might prescribe you a different type of antibiotic if you’re allergic to Doxycycline, pregnant or breastfeeding, or get side effects from Doxycycline.

Chlamydia doesn’t usually clear up by itself. If you don’t get treated you risk spreading the infection to other partners. You’re also risking long-term health complications.
