What is Doxycycline & how does it treat chlamydia?

Doxycycline 100mg capsules (chlamydia antibiotics) are available to buy from The Independent Pharmacy service, following a free consultation, to treat chlamydia in those who have had a positive chlamydia test or have had unprotected sex with someone who has. To find out more about chlamydia and see all the available treatments, see our Chlamydia page.

Doxycycline is an antibiotic used to treat chlamydia infections. Doxycycline is normally the first choice treatment for chlamydia, ahead of another antibiotic, Azithromycin. Doxycycline is equally as effective as azithromycin but has been recommended as the first-line treatment for chlamydia due to the decreased chance of bacterial resistance. This gives your treatment the highest chance of being effective. Doxycycline treatment needs to be taken twice daily for 7 days and you should always complete the course, even if your symptoms disappear.

Doxycycline is a broad-spectrum antibiotic. It is effective against a wide array of bacteria that are responsible for causing various types of infection. When being taken to treat the sexually-transmitted disease chlamydia; one 100mg capsule is taken twice daily for a week. A follow up course is not usually necessary. A 7-day course of Doxycycline will normally clear up most cases of chlamydia within 7 days. You can take another chlamydia test 14 days after your treatment to ensure the infection has cleared up.

Doxycycline is categorised as a prescription only medicine (POM). It is available as a generic tablet as well as the branded version Vibramycin-D. Doxycycline preparations can also be used to treat many different types of bacterial infections, such as respiratory infections, skin infections, ear infections and sexually transmitted infections (STI’s), such as chlamydia.

More information about chlamydia treatment:

  • Avoid sexual contact whilst taking doxycycline and for 7 days afterwards, until no longer infectious.
  • People with a positive chlamydia test and their sexual partners should be treated, at the same time if possible.
  • Tests can take 6 weeks or more to go negative after chlamydia has been successfully treated. It is not currently recommended to re-test after you have taken treatment.

Buy doxycycline for the treatment of chlamydia online from The Independent Pharmacy and have it delivered as quickly as the next working day.

*Prescription medicines are supplied subject to a medical consultation at the discretion of a doctor.

Doxycycline dose for chlamydia

  • Always ensure you complete the prescribed course.
  • You should take Doxycycline with or after food and with a full glass of water.
  • Do not have sex for SEVEN days after treatment is complete.

Other side effects from doxycycline are rare.

Doxycycline can cause skin sensitivity to light. This means your skin will burn much more quickly under UV light than normal. Strong sun and sun beds should be avoided whilst doxycycline is being taken. If you do go out in strong sunlight, ensure you cover your skin or wear strong sunblock.

Frequently Asked Questions

  • When taking Doxycycline, how long do I have to wait before I can again have sex?

    It is imperative that you refrain from sexual activity, whether it be vaginal, oral or anal, even when wearing a condom, until you and your sexual partner(s) have been tested and have completed the treatment.

    Doxycycline is a seven-day course and sex should be avoided both during this seven day period and the following seven days after the course of medication has finished, so as to avoid reoccurrence.

  • Will I have to return to the clinic?

    If the medication is taken as directed, it may not be necessary to return, though you may need another chlamydia test if:

    • The symptoms are still there
    • You have been treated whilst pregnant
    • You didn’t take the medication as directed
    • You had sex before the two week period of abstinence had come to an end.
  • Will my GP know about my treatment?

    We only contact your GP if you request us to do so and only with your written consent.

    However, our medical staff, who work to ethical guidelines, do recommend that you inform your doctor of this health condition and its treatment.

  • Does doxycycline work?

    This medication is very effective and, if you have taken the medication in the manner directed, you may not need a follow-up chlamydia test.

  • Does it take long to cure chlamydia?

    When taken as directed, a full course of doxycycline or azithromycin, will clear chlamydia within seven days. Should you experience side-effects, you will need another test.

  • Why use Doxycycline?

    An antibiotic, doxycycline is used for the treatment of STIs (sexually-transmitted infections) and also for the prevention of malaria. It works by making the parasites or bacteria, which need to produce protein to survive, become vulnerable.

    The body's immune system can then fight the infection and reduce the spread of infection.

  • Are there any benefits to using Doxycycline?

    Doxycycline needs only a low dose to treat sexually-transmitted diseases. If other antibiotics have caused side-effects, doxycycline can be prescribed as an alternative.

  • Why have my symptoms not cleared up?

    This could be due to several reasons:

    • The symptoms could be from some other cause
    • It is possible to have two or more STIs at the same time
    • The symptoms may relate to an infection in the urinary tract or, in women, could relate to endometriosis
    • If you have unprotected sex with someone who is infected, or not yet clear of an infection, you could become re-infected.

    Antibiotics work well on sexually-transmitted infections so, if your condition has not cleared, seek advice from your local GUM (genitourinary medicine) clinic or your doctor. In this case, you may need a second chlamydia test about six weeks after the initial test.

  • Can I take the second chlamydia test soon after the first test, so as to be sure that the medication has worked?

    Taking a second test too soon after the first one may give a result of positive to the infection, or be because of re-infection, so that's why you are asked to wait six weeks.

  • Can I become re-infected, if my partner didn’t take the treatment as well?

    It is very important that you both abstain from sex (even with a condom) until the treatment has taken effect and to wait two weeks from the start of treatment, by which time the infection will have gone.

  • If I am taking doxycycline and I vomit, does that mean that the treatment will not be effective?

    Missing out on one pill through vomiting shouldn’t affect the success of the medication, so continue to take all pills in the course prescribed.

    Missing several pills could affect the success of the treatment.

  • What happens if I forget to take a pill?

    Take the tablet as soon as you remember that you have forgotten.

    However, if you don’t remember until the next day, do not take a double dose.

    Having missed one pill may therefore reduce the effectiveness of the course of medication so, if you think it is possible that you might miss a day, ask for azithromycin instead.

  • Is drinking alcohol permitted when on this medication?

    Alcohol can reduce the effectiveness of the treatment, so do not drink any alcohol whilst on the course of medication.

  • Will this medication affect my capacity to drive?

    Doxycycline shouldn't affect driving but, if you think you are experiencing some side-effects which could affect your capacity to drive, speak with your doctor about it.

  • Am I allowed to take doxycycline while pregnant?

    If you are pregnant, hoping to become pregnant or are breastfeeding, make sure your doctor is aware of this, so that he can prescribe accordingly.

  • Does doxycycline need any special storage method?

    Simply store it at room temperature and keep it safe from children.

  • Can doxycycline be bought over the counter?

    In the UK, it is a prescribed medication only.  If you attend The Independent Pharmacy for doxycycline, you will need to complete a medical survey and have your case assessed, before doxycycline will be prescribed.
