What is Doxycycline and what does it do?

Doxycycline is a bacteriostatic medicine and belongs to a group of drugs known as antibiotics. It is a so called broad-spectrum antibiotic which means it is effective on a wide range of bacteria.

Doxycycline is used to treat a wide range of conditions. This text will focus on how and when it is prescribed to prevent malaria when visiting high risk areas.

When is Doxycycline prescribed?

Doxycycline can be prescribed to prevent malaria when travelling to malaria risk areas. If you are travelling abroad, it is important to find out whether you will require anti-malarials or not. High risk areas include, but are not limited to large areas of Africa and Asia, Central and South America and parts of the Middle East.

To find our whether the country you are visiting belongs to any of the Malaria risk areas, visit the NHS Fit for Travel website.

No antimalarial treatment gives complete protection against Malaria, so it is important that you also take other preventative measures to decrease the risk as much as possible. Always use mosquito repellent and clothing to protect yourself and if possible a mosquito net at night.

Is Doxycycline suitable for my condition?

This will be determined by our doctors. When you request your prescription, we ask you to submit a medical questionnaire. The information you provide will be assessed by our doctors to ensure this treatment is suitable and safe for you to use.

Doxycycline may not be suitable and may not be prescribed if any of the below applies to you:

  • Are allergic or sensitive to Doxycycline or any of the ingredients listed in the patient information leaflet.
  • Are pregnant, are trying to become pregnant or are breastfeeding.
  • Are likely to be exposed to strong sunlight or ultraviolet light.
  • Have liver problems or severe kidney problems.

Note: Doxycycline can affect oral contraceptives (“the pill”) and make it less effective. You are advised to use additional contraception such as condoms or other barrier methods while taking doxycycline.

Doxycycline may interact with other medicines. Always tell our doctors if you are taking any other medicines. You must include this information when you submit the medical questionnaire.

What is the recommended dosage of Doxycycline?

You should follow the doctor’s instructions on how to take this medicine. The doses outlined below is for your reference only. Swallow the capsule whole with a glass of water. Take the capsule while standing up or sitting. Do not lie down for at least 30 minutes after taking the tablet.

Never exceed the stated dose.

Doxycycline doses for preventing malaria

Take 100mg (1 capsule) once a day. Start taking doxycycline 1 - 2 days before travelling. Keep taking the medicine for the full duration of your stay and for 4 weeks after returning.

Note: Alcohol may reduce the effect of doxycycline. You should avoid drinking alcohol while taking doxycycline.

Does Doxycycline cause any side effects?

Yes, just like all medicines doxycycline may cause side effects. However, not everyone will get them. It is important that you read through the patient information leaflet before use so that you know how to recognise side effects and when to seek medical advice.

Common side effects associated with taking doxycycline include:

  • Upset stomach.
  • Feeling sick or being sick.
  • Diarrhoea.

Contact your GP immediately if you notice any signs of an allergic reaction, such as difficulty breathing, sudden swelling of the face, lips or tongue, rash or itching.

Can I reduce the risk of getting side effects?

Yes. You should always read the patient information leaflet thoroughly before use as this can help reduce the risk of side effects and interactions between medicines. Below are a few things you can do:

  • While filling in the medical questionnaire, remember to include any other medicines you are taking. Doxycycline can affect how other medicines work, so it is important that you tell our doctors about all medicine you take. Don’t forget to also include over the counter medication and supplements.
  • Take doxycycline with food or a milky drink if you experience stomach upset.
  • Take doxycycline at the same time every day.

How do I buy Doxycycline online?

To legally and safely buy doxycycline online you need a prescription from a GMC (General Medical Council) registered doctor. Our online doctor service allows you to request a prescription through a medical questionnaire.

Once you have chosen your medicine and submitted the questionnaire, it will be reviewed by one of our doctors. If suitable, the doctor will accept your request and a prescription will be issued. Your medicine will then be dispensed by our UK pharmacy and sent by tracked delivery to your chosen address. Your medicine is usually dispatched within 24 hours after ordering.
