What is doxycycline?

Doxycycline belongs to a class of antibiotics called tetracyclines. It is one of the most commonly prescribed antibiotics to treat chlamydia.

It's also used to treat other sexually transmitted infections (STIs) and other infections like chest infections, skin infections, rosacea, and dental infections as well as many other rare infections. Doxycycline can also be used to prevent malaria if you’re travelling abroad.

Doxycycline may also be known by the brand name Vibramycin D.

How does doxycycline treat chlamydia?

It's an antibiotic that stops the spread of bacteria causing chlamydia by preventing them from producing the proteins they need for survival.

Does doxycycline completely get rid of the chlamydia infection?

If doxycycline is taken correctly, there's more than a 95% chance that it will cure chlamydia. However if you are under the age of 25 a repeat chlamydia test is recommended after 3 months.

Will it prevent me from getting chlamydia again?

No, it does not protect or prevent you from getting chlamydia again. Doxycycline will only treat your chlamydia as a one-off occasion so it's very important to practice safe sex methods after you've been treated.

Do I need a prescription for doxycycline?

Yes, you can get doxycycline online with ZAVA, provided you are suitable for treatment. You would need to tell us how you know you need chlamydia treatment.

How do I buy doxycycline online?

To place an order, fill in our brief consultation questionnaire. Our doctor will review your request and check whether chlamydia treatment is suitable for you. Once your order has been approved, we'll dispense and post your medication.

Advantages to getting treatment with ZAVA are that we offer a discreet, simple, and fast service.

We also have different delivery options to suit you, which you can choose at the checkout. Delivery options may vary depending on the pack size and dosage chosen. We also offer a free delivery service.

What are the alternatives for getting treatment?

Doxycycline is a prescription only antibiotic. You can also get treatment from your GP or local sexual health or genito-urinary (GUM) clinic.

How do I know I need doxycycline?

The only way of knowing you have chlamydia is to get tested. It's important not to leave chlamydia untreated as it can cause serious long term problems like infertility and pelvic inflammatory disease.

You'll be eligible for treatment if you've tested positive after getting tested either at home, from your GP or local GUM/sexual health clinic and your doctor has confirmed your infection. You would also be eligible if you've had unprotected sex with a partner who has a confirmed chlamydia infection.

You will not be able to get treatment if you've had unprotected sex with a partner whose STI status you're unsure of, or if only you have symptoms. In this case, you would need to get tested before you could get treatment.

You can order a home testing kit from us or get tested from:

  • ZAVA's chlamydia home test kit
  • your GP surgery
  • a sexual health clinic
  • a genitourinary clinic (GUM)
  • most contraceptive or young people’s clinic
  • some pharmacies

Abortion, antenatal, or gynaecology services may also offer women a chlamydia test.

Local councils also pay for free testing in men and women under the age of 25 in their area, as part of the National Chlamydia Screening Programme (NCSP). They may also locally advertise outreach testing in places such as colleges, youth clubs or military bases.

You can also order a free NHS home self-testing kit. This is available online only in certain areas from the NHS website.

Diarrhoea or are having problems with your stomach or intestines – if you develop severe or prolonged or bloody diarrhoea during or after using doxycycline tell your doctor immediately since it may be necessary to interrupt your treatment. This may be a sign of bowel inflammation (pseudomembranous colitis) that can occur with taking antibiotics.

Do other medicines affect doxycycline?

Some medicines interact with doxycycline and should not be taken together. Speak to your doctor or pharmacist for further advice if you are taking any of the following:

  • Anticoagulants such as warfarin
  • Quinapril – used to treat high blood pressure

  • Retinoids – used to treat various skin conditions
  • Antacids (indigestion tablets or liquids) containing aluminium, calcium, magnesium or other medicines containing iron, bismuth or zinc salts, should not be taken at the same time as Doxycycline as its absorption can be reduced.

Doxycycline will not affect your ability to drive or use machines. However, if you think you feel unwell after taking the medication, do not put yourself and others at risk.

Do not drink alcohol while you're taking doxycycline, as it can increase the risk of side effects and liver problems.

How do I know doxycycline is right for me?

Based on your chlamydia test results, your medical history and other medicines you are taking your doctor will assess if it's the right treatment for you.
