Product information

Doxycycline is an antibiotic tablet, known as a tetracycline. This medication has a versatile range of uses, and is a generic version of the treatment otherwise sold as Vibramycin-D by Pfizer. It treats bacterial infections such as chlamydia. It is also sometimes used in malaria prophylaxis for those travelling to certain regions.

(Presently, we only offer this treatment for chlamydia through our service.)

Doxycycline for chlamydia

Chlamydia is the most common sexually transmitted infection in the UK, with around 200,000 reported instances per year. It can be spread through vaginal, anal or oral sex, or through the use of shared sex toys.

In many cases (around half of those occurring in males and 80 percent of those in females) the infection is symptomless, so it is possible to have chlamydia and not know. Where it does cause symptoms, these may include: vaginal discharge or irregular bleeding in women; or testicular pain or discharge from the penis in men.

Even where chlamydia is symptomless, when left untreated it can lead to complications such as pelvic inflammatory disease in women, or infertility in both sexes; so it is important to get tested regularly if you’re sexually active, or get tested as soon as possible if you think you might have come into contact with the infection.

Currently, the preferred treatments for chlamydia according to NICE guidelines are Doxycycline or Azithromycin. Doxycycline is the typical go-to treatment where infection occurs in the rectum.

Patients who have tested positive for chlamydia can order treatment online through our site. We generally recommend Azithromycin in the first instance, but if this treatment is not suitable for you, our doctor may suggest taking Doxycycline instead.

Whereas Azithromycin is a one-off dose, Doxycycline is a twice daily dose for one week.

Your answers will be reviewed by our doctor, who will issue a prescription for your treatment following approval. This will then dispensed at our UK pharmacy and shipped to you by next-day courier.

If you haven’t been tested for chlamydia, but think you may come into contact with it, you should get tested as soon as possible. You can either do this by ordering one of our test kits online, or by visiting your GP or local sexual health clinic.

Use in malaria

Doxycycline is also sometimes prescribed as an antimalarial. Malaria is a potentially very serious illness, caused by the plasmodium parasite. This is transmitted from mosquitoes to humans through bites.

Due to the existence of several strains in different regions around the world, there are a number of treatments available for malaria. The NHS Fit For Travel website provides country-specific guidance for travellers on malaria.

Please note we do not offer malaria treatments through our site at present. To find out more about which antimalarial is suitable for you, speak to your GP or local travel clinic.

Getting Doxycycline treatment online

If you think you may have chlamydia, you should get tested as soon as possible. This will enable a doctor to identify the infection and issue an appropriate treatment. You can either get tested in person by visiting your local GUM clinic. Home test kits for chlamydia are also available through our site.

Patients who have received a positive test result for genital chlamydia are normally advised to take Azithromycin, as this is the preferred treatment at present. However, if this is not suitable, or if there are signs of a rectal chlamydia infection, then Doxycycline can be recommended as an alternative.

If you have a positive test result, take our questionnaire to begin your consultation and buy Doxycycline online. Orders are checked by a registered prescriber, and shipped from our UK pharmacy once approved, by next-day delivery.
