Frequently Asked Question

Doxycycline for malaria prevention

You need to start taking doxycycline two days before you enter an area where malaria is endemic. You need to continue taking it throughout your trip for as long as you’re at risk of catching malaria and for four weeks after your return.

The malaria parasite can take some time to multiply and cause symptoms – it is important that you finish the full course you have been prescribed to ensure that you are fully protected.

While taking doxycycline, you should avoid drinking alcohol as it could reduce the effectiveness of your medication and increase your risk of catching malaria.

In addition to taking your tablets, make sure you practise insect bite avoidance by using insect repellent and a mosquito net.

If you experience malaria symptoms at any point during or after your trip, seek medical help without delay. Antimalarials are very effective when taken correctly but a very small risk of infection remains.

How to take doxycycline

Take your daily dose with a drink of water, ideally at the same time every day. Don’t lie down for half an hour after taking the tablet as this will reduce your risk of side effects such as nausea and an upset stomach.

If you have forgotten to take one dose, take it as soon as possible and then continue by taking the next tablet at the correct time. Don’t take a double dose to make up for the one you have missed.

Who can take it?

When you visit one of our clinics, the nurse or pharmacist will assess which antimalarial is best for you. They will take into account your medical history and where you are travelling to as well as your preference.

Doxycycline may not be suitable for you if you are pregnant or trying for a baby. It is also not suitable for women who are breastfeeding and children under the age of 12.

If you have had an allergic reaction to doxycycline or a similar antibiotic in the past, you will need to use a different antimalarial. The same may apply if you suffer from certain medical conditions, for example kidney or liver problems, lupus or porphyria. You may also be unable to take doxycycline if you are taking any medications that interact with it.

In some cases, doxycycline has been found to increase your sensitivity to sunlight and to increase your risk of sunburn. If you are likely to be exposed to direct sunlight for long periods of time, the nurse or pharmacist may recommend a different antimalarial.

Side effects

As other antimalarials, doxycycline can cause side effects in some patients.

Allergic reactions to doxycycline are very rare but can be serious.

Symptoms of an allergic reaction include:

  • Wheezing and difficulty breathing
  • Chest pain
  • Swellings
