Malaria Prevention for UK Travellers: Choosing the Right Tablets for Your Destination
Malaria remains one of the most serious health risks facing UK travellers heading to parts of Africa, Asia, Central and South America, and the Middle East. Choosing the right malaria tablets UK travel clinics recommend for your specific itinerary is not a decision to make from an internet forum or a pharmacy shelf alone. Resistance patterns, trip length, cost, and your own medical history all shape which tablet suits you best.

Quick Answer
There is no single “best” malaria tablet for every traveller. The right choice depends on your destination’s resistance patterns, how long you are travelling, your budget, and your medical history. The main options available in the UK are atovaquone/proguanil (Malarone and generic equivalents), doxycycline, and mefloquine (Lariam), each with different dosing schedules, costs, and side effect profiles. A travel health consultation will match the right tablet to your trip.
Read on to understand your options for malaria tablets UK clinics prescribe, how they compare, and how to plan ahead so you are protected before you travel.
1. Why Malaria Prevention Still Matters for UK Travellers
Malaria is caused by parasites spread through the bite of infected Anopheles mosquitoes, mostly between dusk and dawn. It remains present across large parts of sub-Saharan Africa, South and Southeast Asia, Oceania, and parts of Central and South America. According to UK surveillance data, several thousand cases are imported into the UK each year by returning travellers, and a small number of these prove fatal, almost always because prevention was skipped or medication was taken incorrectly.
There is no vaccine routinely available for UK travellers that replaces the need for tablets, so anti-malarial medication combined with bite avoidance remains the cornerstone of prevention. Key points to understand from the outset:
- ⇾ Malaria risk varies enormously by country, and even by region within a country
- ⇾ Some strains of malaria parasite are resistant to older, cheaper medications in certain regions
- ⇾ Tablets are only part of the picture; mosquito bite avoidance measures are equally important
- ⇾ Pregnant travellers, young children, and those with certain health conditions need specialist advice
- ⇾ Buying tablets without a proper risk assessment can mean the wrong drug for your destination
2. The Main Malaria Tablets Available in the UK
Your clinician will choose from a small number of established options when discussing malaria tablets UK guidance recommends, based on your itinerary and health profile.
Atovaquone/proguanil (Malarone and generics): Taken daily, starting one to two days before entering a risk area and continued for seven days after leaving. Generally well tolerated with fewer side effects, but usually the most expensive option for longer trips
Doxycycline: Taken daily, starting one to two days before travel and continued for four weeks after leaving. Usually the cheapest option, but can cause sun sensitivity and is not suitable in pregnancy or for children under twelve
Mefloquine (Lariam): Taken weekly, starting two to three weeks before travel to check tolerability, and continued for four weeks after leaving. Convenient weekly dosing, but unsuitable for those with a history of depression, anxiety, or certain other psychiatric conditions
Chloroquine and proguanil: An older combination now rarely used, because resistance is widespread across most malaria risk areas. Occasionally still appropriate for a small number of low-risk destinations
No tablet offers 100 percent protection. All must be combined with mosquito bite avoidance measures, including repellent, appropriate clothing, and sleeping under treated nets where needed.
3. Comparing Cost, Dosing, and Duration
Cost is often the deciding factor once two or more tablets are clinically suitable for a destination. The table below gives a general comparison to help you understand the trade-offs before your consultation.
| Tablet | Dosing Schedule | Start Before Travel | Continue After Return | General Cost Level |
|---|---|---|---|---|
| Atovaquone/proguanil | Once daily | 1 to 2 days | 7 days | Higher |
| Doxycycline | Once daily | 1 to 2 days | 4 weeks | Lower |
| Mefloquine (Lariam) | Once weekly | 2 to 3 weeks | 4 weeks | Moderate |
| Chloroquine + proguanil | Weekly + daily | 1 week | 4 weeks | Moderate |
Prices vary between providers and are confirmed at your consultation, since they depend on trip length and the specific product prescribed. As a general rule, longer trips make the daily tablets (atovaquone/proguanil and doxycycline) cost more overall, which is why some longer-stay travellers, where clinically suitable, opt for weekly mefloquine instead.
4. Side Effects and Who Should Avoid Certain Tablets
Every anti-malarial carries a different side effect profile, and your clinician will screen for contraindications before prescribing.
Atovaquone/proguanil: Generally mild side effects such as nausea or headache; avoided in severe kidney impairment
Doxycycline: Can cause sun sensitivity, indigestion, and vaginal thrush; unsuitable in pregnancy, breastfeeding, or for children under twelve
Mefloquine: Vivid dreams are common; unsuitable for anyone with a history of depression, anxiety, seizures, or certain heart rhythm problems
Chloroquine and proguanil: Generally well tolerated but limited by widespread resistance in most current risk areas
It is essential to disclose your full medical history, current medications, and any previous reactions to anti-malarials at your consultation. This is also why starting mefloquine two to three weeks ahead is recommended, so any unsuitable side effects appear before you travel rather than during your trip.
5. Beyond Tablets: Bite Avoidance and Practical Planning
Medication for malaria tablets UK clinics prescribe is only ever part of a complete prevention strategy. Combine tablets with the following measures for the best protection:
- ⇾ Use a DEET-based repellent (usually 20 to 50 percent concentration) on exposed skin, reapplied as directed
- ⇾ Wear long sleeves and trousers, particularly between dusk and dawn when Anopheles mosquitoes feed
- ⇾ Sleep under a permethrin-treated mosquito net if accommodation is not fully screened or air-conditioned
- ⇾ Take your tablets at the same time each day or week to maintain protective drug levels
- ⇾ Never stop tablets early, even if you feel unwell; seek advice instead of self-adjusting the dose
- ⇾ Set a reminder for your post-travel dosing period, since many cases occur because travellers stop tablets on the day they land home
- ⇾ Report any fever within a year of travel to a doctor immediately and mention your travel history, as malaria can present late
Booking your consultation four to six weeks before departure gives enough time to start mefloquine if that is the most suitable option, and leaves room to address any other travel health needs such as vaccinations at the same appointment.
6. What Happens if You Skip Malaria Tablets
Some travellers are tempted to skip prevention, either due to cost, previous trips without illness, or a belief that a destination is lower risk than it is. This is a significant gamble. Malaria can cause a severe, rapidly progressing illness, and in the case of Plasmodium falciparum, the most dangerous species, symptoms can escalate from fever to organ failure within days without treatment. Key risks of skipping prevention include:
- ⇾ Underestimating risk in destinations perceived as low risk, such as popular safari regions or coastal resort areas near higher-risk zones
- ⇾ Delayed diagnosis after return, since GPs unfamiliar with a patient’s travel history may not immediately suspect malaria
- ⇾ Increased severity of illness in those without previous exposure, which includes almost all UK travellers
- ⇾ Higher risk to pregnant travellers, where malaria can cause serious complications for both mother and baby
If you develop a fever, chills, or flu-like symptoms at any point within a year of returning from a malaria risk area, seek urgent medical attention and tell the clinician exactly where you travelled. If you are concerned about ongoing symptoms after travel, a post-travel blood test can also help identify or rule out a range of travel-related illnesses.
7. Special Considerations: Long Stays, Repeat Trips, and Combined Travel Health Needs
Not every traveller fits the standard two-week holiday pattern, and malaria prevention needs adjusting for a number of common situations that come up regularly at travel health consultations.
Long-term stays and expatriates: Taking daily tablets such as atovaquone/proguanil for many months is not usually recommended, since it is designed for shorter courses. Longer stays often call for weekly mefloquine, or a reassessment of risk alongside stricter bite avoidance, and this should always be discussed individually
Frequent business travellers: Repeated short trips to the same malaria risk region may still require a full course each time, since protection does not carry over between trips once tablets are stopped. Keeping a note of previous prescriptions speeds up repeat consultations
Multi-country itineraries: Risk can change significantly as you cross borders, even within the same region. A detailed itinerary, including any overland travel through lower-altitude or rural areas, helps your clinician choose the right tablet and course length
Combining with other travel health needs: Many travellers heading to malaria risk destinations also need vaccinations such as yellow fever, typhoid, or hepatitis A. Booking one consultation that covers both malaria prevention and vaccination needs saves time and ensures nothing is overlooked
Previous adverse reactions: If you have had side effects from an anti-malarial on a previous trip, mention this clearly at your consultation, since an alternative tablet is usually available
Because personal circumstances vary so widely, there is no substitute for a proper consultation. A ten or fifteen minute conversation with a clinician who understands both your health history and your itinerary is what actually determines the right malaria tablets UK travellers in your exact situation should take, rather than a generic recommendation found online.
Frequently Asked Questions About Malaria Tablets UK
Which malaria tablet is cheapest?
Doxycycline is generally the least expensive option for most trip lengths, since it is available as a low-cost generic. However, it is not suitable for everyone, including pregnant travellers, breastfeeding mothers, and children under twelve, so cost should never be the only factor in your decision.
Can you buy malaria tablets over the counter in the UK?
No. All effective anti-malarial medications are prescription-only in the UK. This is because the correct choice depends on an individual risk assessment covering your destination, medical history, and other medications, which is why a travel health consultation is required before any tablets can be supplied.
What happens if I miss a dose?
Take the missed dose as soon as you remember, unless it is almost time for your next one, in which case skip the missed dose and continue as normal. Do not double up doses. If you miss more than one dose or are unsure, contact your travel health clinician for advice specific to the tablet you are taking.
Do tablets work alongside mosquito nets and repellent?
Yes, and they should always be used together. No anti-malarial tablet offers complete protection on its own. Repellent, appropriate clothing, and treated nets significantly reduce the number of bites you receive, which lowers your overall risk alongside medication.
How far in advance should I book my malaria consultation?
Aim for four to six weeks before departure. This allows enough time to trial mefloquine if it is the most suitable tablet for your trip, since side effects need to be checked before you travel, and leaves time to arrange any vaccinations you may also need.
Can children and pregnant travellers take malaria tablets?
Some anti-malarials are unsuitable in pregnancy or for young children, while others may be prescribed with caution depending on the trimester or the child’s weight. Pregnant travellers are generally advised to avoid non-essential travel to malaria risk areas altogether, and should discuss this in detail with a clinician.
Do I still need tablets for a short trip of a few days?
Yes. Malaria risk is not related to trip length, and a single infective mosquito bite on a short business trip or stopover in a risk area is enough to cause infection. Short trips still require a full course of tablets, taken for the correct period before and after travel.
Plan Your Trip With the Right Protection
Choosing the right malaria tablets UK travellers need is a decision best made with a qualified clinician who understands your itinerary in detail. Do not rely on advice from previous trips, friends, or online forums, since resistance patterns and personal health circumstances change the right answer every time.
