About chlamydia treatment

  • Taking chlamydia treatment

    Take 1 tablet, twice a day, for 7 days. Swallow the tablet with plenty of water.

    Doxycycline is best taken with food, or a glass of milk, and should be taken at least one hour before you go to bed.

    Complete the 7-day course of treatment to clear the infection. Do not have sex until you have completed all 7 days of treatment.

    If you are allergic to Doxycycline, you will be prescribed an alternative antibiotic.

  • How do chlamydia tablets works

    Doxycycline is an antibiotic. It can be used to treat chlamydia by killing the bacteria that cause the infection.

  • Effectiveness of chlamydia treatment

    When taken correctly, the prescribed treatment will kill the bacteria causing the infection. You should avoid sexual contact until you and any sexual partners have completed the course of antibiotics.

    This medicine is not a vaccination. You must take precautions to avoid reinfection. Using condoms every time you have sex (oral, vaginal, anal) is the best way to make sure you do not get STIs.

  • Chlamydia treatment side effects

    The most common side effects include sensitivity to sunlight (exaggerated sunburn reaction), indigestion (inflammation or ulcers of the gullet) and, in women, vaginal thrush.

    For full information on side effects and correct use, see the patient information leaflet. If any side effects concern you, contact us via your Patient Record.
