Quick Summary

Doxycycline

Antibiotic used to prevent malaria when travelling to high-risk areas.

Doxycycline – a tetracycline antibiotic that stops the malaria parasite from multiplying.

Prevents malaria parasites from growing in the blood after mosquito bites.

Side effects

May cause nausea, sun sensitivity, or stomach upset.

Doxycycline for malaria prevention

Choose malaria protection based on your destination and health history. Doxycycline is one option our prescriber can assess for your trip, alongside atovaquone/proguanil, the generic alternative to Malarone.

Plan enough capsules for the whole course

The usual adult prevention schedule is one 100mg capsule daily, starting one or two days before entering the malaria-risk area, throughout your stay and for four weeks after leaving.

This pack contains 50 capsules. The number needed depends on your itinerary, including the doses before and after time in the risk area. Share your exact dates so the prescriber can confirm the right supply.

Doxycycline or atovaquone/proguanil?

Both are taken daily, but atovaquone/proguanil usually continues for seven days after leaving the risk area, while doxycycline continues for four weeks. Compare the cost of the complete prescribed course as well as the pack price.

Before you travel

Complete your assessment early and tell us about all medicines and medical conditions. Follow the supplied instructions, take precautions against mosquito bites and seek urgent medical advice if you develop fever during or after travel.

FAQs

Doxycycline frequently asked questions

Check how to take your capsules and what to discuss during your travel assessment.

Start Consultation

For malaria prevention, start the prescribed course one or two days before entering the risk area, take it daily throughout your stay and continue for four weeks after leaving. Do not wait for symptoms to begin treatment. If you are taking doxycycline for another condition, follow the separate advice given by your prescriber.

Drinking alcohol while taking Doxycycline can reduce its effectiveness and may make the treatment less reliable. It’s best to avoid alcohol until you finish the full course.

Take the missed dose as soon as you remember. If it's almost time for your next dose, skip the missed one—do not take a double dose.

Some medicines, such as antacids, iron supplements, and blood thinners, can interfere with how Doxycycline works. Always check with a doctor or pharmacist before combining treatments.

Swallowing Doxycycline with plenty of water and remaining upright for at least 30 minutes helps prevent irritation or damage to the throat and oesophagus.
