Introduction
Malaria tablets can reduce the risk of malaria when they are recommended for your exact destination and taken correctly. There is no single tablet that is “best” for every traveller. The right option depends on the country and region, local drug resistance, trip length, age and weight, pregnancy or breastfeeding, medical history, current medicines and the practical likelihood that you will complete the whole course.
The main options commonly considered for UK travellers are atovaquone/proguanil, doxycycline and mefloquine. Their dosing schedules, side effects, contraindications and total course lengths differ. Some destinations need tablets only in defined regions, while other itineraries may require mosquito-bite precautions and awareness rather than chemoprophylaxis.
Before comparing prices, check your route using the TravelJabs4U destination vaccine guide and arrange an individual assessment. You can then find a participating travel clinic to discuss a clinically suitable option.
Do You Need Malaria Tablets for Your Trip?
Malaria advice must use the exact itinerary rather than the country name alone. Risk can vary within one country by province, altitude, season, urban or rural setting, accommodation and access to medical care. A traveller staying in a major city may receive different advice from someone crossing a forested border area in the same country.
UK guidance recommends an individual risk assessment before chemoprophylaxis is chosen. The assessment should cover every overnight stop and side trip, not only the airport or main resort. It should also identify travellers who may be at increased risk of severe malaria, including pregnant travellers, young children, older people, people with immune suppression and those without a functioning spleen.
Even where malaria tablets are advised, they are not completely protective. Correct dosing must be combined with mosquito-bite prevention and prompt medical assessment if fever or other possible malaria symptoms develop during travel or after return.
Types of Malaria Tablets Used in the UK
The table below is a practical comparison for adults. It is not a prescribing tool. Doses for children and people below adult weight thresholds must be calculated and checked by an appropriately qualified clinician or pharmacist.
Atovaquone/Proguanil
Atovaquone/proguanil is taken once daily and is commonly chosen when a short post-travel course is important. UKMEAG advises starting one to two days before entering a malaria-risk area, continuing throughout exposure and taking it for seven days after leaving. It should be taken with food or a milky drink to support absorption.
The product may be branded as Malarone or supplied as a generic equivalent. A lower advertised Malarone price in the UK does not establish that it is the right option for a particular traveller. Kidney function, pregnancy, breastfeeding, vomiting or diarrhoea, warfarin and several interacting medicines can affect suitability or effectiveness. Some atovaquone/proguanil products can be supplied by a pharmacist to eligible adults without a prescription, but an assessment is still required.
Doxycycline for Malaria Prevention
Doxycycline is taken daily, starting one to two days before entering the risk area and continuing for four weeks after leaving. Because the post-travel period is longer, the total number of capsules can be substantially greater than the number of days spent abroad. The full course should be included when comparing antimalarial tablets cost.
Doxycycline should be swallowed with plenty of fluid while sitting or standing, and the traveller should not lie down for at least an hour afterwards. This reduces the risk of irritation or ulceration in the oesophagus. It can increase sensitivity to sunlight, and absorption can be affected by antacids and supplements containing aluminium, calcium, magnesium, iron, zinc or bismuth. It is not suitable for children under 12 and is generally avoided for malaria prevention in pregnancy.
Mefloquine (Lariam)
Mefloquine is taken weekly and is started earlier—normally two to three weeks before entering the malaria-risk area—so tolerability can be assessed before departure. It is continued weekly during exposure and for four weeks after leaving. The weekly schedule can be convenient for some longer trips, but missing a weekly dose can undermine protection.
Mefloquine requires careful screening. It should not be used in people with specified current or previous psychiatric disorders, epilepsy or convulsions, and it may be unsuitable in several other circumstances. Abnormal dreams, insomnia, anxiety, depressed mood, dizziness, balance problems and vertigo can occur. New psychiatric or neurological symptoms need prompt medical advice and may require the medicine to be stopped or changed under professional guidance.
How Much Do Malaria Tablets Cost in the UK?
The total price depends on the medicine, brand or generic product, adult or paediatric strength, number of days in the risk area, required pre-travel and post-travel doses, consultation or private-prescription fee, and the supplying clinic or pharmacy. A low per-tablet price can still produce a longer or more expensive full course when the medicine must continue for four weeks after travel.
At the time of this audit on 23 July 2026, the existing TravelJabs4U malaria service page displayed doxycycline from £10 per week. This should be treated only as a starting price from the current service page. The developer must confirm the exact applicable provider, quantity, consultation or prescription fee, and any delivery terms immediately before publication.
Do not use a price from one participating clinic as a network-wide TravelJabs4U price. Malarone, generic atovaquone/proguanil and mefloquine prices can vary materially between providers and by course length. The most useful quote is a complete-course price after the destination and medicine have been assessed.
Where Can You Get Malaria Tablets in the UK?
Malaria prevention medicines can be obtained through travel clinics, some community pharmacies and other regulated services that provide an appropriate assessment. Depending on the product and traveller, supply may be by prescription, patient-specific clinical supply or pharmacist sale. A booking does not guarantee that a particular medicine will be recommended or available.
Obtain antimalarials from a reputable UK source before travel. UKMEAG warns that antimalarial medicines bought in some destination countries may be fake or substandard, and travellers using online services should check that the provider is bona fide and appropriately regulated.
Book a Malaria Risk Assessment
Bring your full itinerary, travel dates, medical history, current medicines and any previous reactions to antimalarials. The clinician or pharmacist can confirm whether tablets are advised and which options are suitable.

How a Malaria Risk Assessment Chooses a Medicine
A safe comparison begins with clinical suitability, not the cheapest advertised pack. The assessment should normally review:
· every country, region, border crossing and overnight stop;
· season, altitude, rural or urban exposure and accommodation;
· time in the malaria-risk area and the full pre- and post-travel course;
· age and weight, particularly for children and young people;
· pregnancy, plans to conceive and breastfeeding;
· kidney or liver problems, immune suppression and absence of a functioning spleen;
· mental-health history, epilepsy, seizures, heart-conduction problems and previous brain injury where relevant;
· prescribed, over-the-counter and herbal medicines, including anticoagulants, antacids and supplements;
· previous side effects or failure to complete an antimalarial course; and
· the practical ability to take a daily or weekly medicine correctly.
The recommendation may change if the route changes. Tell the provider about onward travel, rural day trips and last-minute changes rather than relying on advice for the original itinerary.
When Should You Start and Stop Malaria Tablets?
Start dates are part of the prevention regimen, not optional preparation. Atovaquone/proguanil and doxycycline are usually started one to two days before entering the risk area. Mefloquine is usually started two to three weeks beforehand so that tolerability can be assessed before travel.
Continue the medicine for the full advised period after leaving the risk area: seven days for atovaquone/proguanil and four weeks for doxycycline or mefloquine. Stopping when the flight leaves the destination can leave a gap in protection. Follow the instructions supplied for the exact product and seek advice promptly after missed doses or vomiting.
Malaria Tablets for Thailand, India and African Destinations
Country names are too broad for a safe yes-or-no answer. Malaria risk can be absent in one city and significant in another region of the same country. Use current destination guidance and provide the exact route during the assessment.
For Thailand, malaria tablets are not routinely needed for every standard tourist itinerary. Risk is concentrated in particular rural forested border areas, while several major cities and islands are listed as having no malaria risk. Review the current Thailand travel vaccination guide and do not choose tablets solely because the country is in Southeast Asia.
For India, current UK guidance recommends chemoprophylaxis for defined higher-risk states and classifies much of the remaining country as low risk, with no risk in some locations. The advice can therefore change between two trips to India depending on the states visited and individual risk factors.
Many destinations in sub-Saharan Africa have high malaria risk, but “Africa” is not a single risk category. The correct medicine can vary with the country, resistance patterns, season and traveller. A statement that everyone visiting Africa should take the same tablet is unsafe and should not be used.
Side Effects and Safety
All antimalarial medicines can cause side effects, and the full patient information leaflet should be read before use. Mild symptoms do not always require a change, but severe, persistent or worrying symptoms need professional advice. Do not replace one medicine with another without confirming that the new option is suitable for the destination and the traveller.
Atovaquone/Proguanil Side Effects
Headache and gastrointestinal symptoms are among the more frequent effects. Vomiting or diarrhoea can reduce absorption. Seek advice about repeat dosing after vomiting and about important interactions, including warfarin, rifampicin or rifabutin, some HIV medicines and metoclopramide.
Doxycycline Side Effects
Doxycycline can cause nausea, stomach irritation, oesophagitis, photosensitivity and candidiasis. Take it with plenty of fluid, remain upright for at least one hour and follow advice on sun protection. Separate it from interacting antacids and mineral supplements as instructed by the prescriber or pharmacist.
Mefloquine Side Effects
Mefloquine may cause abnormal dreams, insomnia, anxiety, depressed mood, dizziness, balance disturbance, tinnitus or vertigo. It is unsuitable for people with several psychiatric or seizure histories. New psychiatric symptoms, confusion, severe anxiety, depression or balance problems require prompt medical advice.
Pregnancy, Children and Complex Health Conditions
Pregnant travellers are at increased risk of severe malaria and should avoid malaria-risk areas where possible. When travel is essential, prevention advice must be provided by a clinician with access to the full itinerary and medical history. Doxycycline is generally avoided for prophylaxis in pregnancy; atovaquone/proguanil and mefloquine require individual assessment against destination risk and available alternatives.
Children need weight-based dosing and age-specific product selection. Doxycycline is unsuitable for children under 12 under current UK guidance. Atovaquone/proguanil and mefloquine paediatric doses depend on weight and should not be improvised by splitting or combining tablets without professional instructions.
Specialist advice may also be needed for people with kidney or liver disease, immune suppression, absent or poorly functioning spleen, epilepsy, significant mental-health history, complex heart conditions or multiple interacting medicines.
Mosquito-Bite Prevention Still Matters
No malaria tablet provides complete protection. Combine the prescribed course with practical bite prevention throughout the risk period:
· use an effective insect repellent on exposed skin and reapply it according to the label; the NHS advises a 50% DEET-based product for malaria-risk travel;
· wear loose long sleeves and long trousers, particularly from dusk to dawn when malaria-transmitting mosquitoes are most active;
· use accommodation with effective air conditioning or intact screens where possible;
· sleep under an insecticide-treated mosquito net when the room is not adequately screened; and
· continue bite precautions even in places where tablets are not advised, because other mosquito-borne infections may still occur.
What to Do if You Develop a Fever During or After Travel
Malaria can become severe quickly, particularly falciparum malaria. Seek urgent medical advice for fever or other possible malaria symptoms during travel or after returning from a malaria-risk area. Tell the healthcare professional exactly where and when you travelled, even if you took tablets correctly.
UK guidance advises that possible malaria within a year of return must be taken seriously. A same-day malaria blood test may be needed. Antimalarial prophylaxis reduces risk but does not rule out the diagnosis, and delayed symptoms can occur with some malaria species.
How to Book Malaria Advice Through TravelJabs4U
TravelJabs4U helps UK travellers locate participating clinics and booking routes. The clinic or pharmacy providing the consultation is responsible for assessing the itinerary, clinical suitability, prescription or supply route, medicine availability and final price.
Prepare the full itinerary, dates in each malaria-risk area, age and weight of every traveller, pregnancy or breastfeeding information, medical conditions, allergies, all medicines and supplements, previous antimalarial experience and the departure date. This information makes the assessment more useful and reduces the risk of an unsuitable or incomplete course.

Conclusion
Malaria tablets are selected by destination and individual risk, not by a universal “best pill” or the lowest advertised price. Atovaquone/proguanil, doxycycline and mefloquine have different start dates, post-travel periods, contraindications and practical trade-offs. The full course—not only the days abroad—must be included when comparing cost.
Check the exact route, arrange an assessment before travel and obtain the medicine from a reputable UK source. Take every dose as instructed, continue for the required period after leaving the risk area, use mosquito-bite precautions and seek urgent medical advice for fever or possible malaria symptoms during travel or within a year of return.

Frequently Asked Questions
Which malaria tablets are best?
There is no best malaria tablet for everyone. The choice depends on the exact destination, local resistance, trip length, age and weight, pregnancy or breastfeeding, medical history, current medicines, side-effect risks and whether a daily or weekly schedule can be completed correctly.
How much do malaria tablets cost in the UK?
The total cost depends on the medicine, brand or generic product, strength, full course length and any consultation, private-prescription or delivery fee. The current TravelJabs4U owner page displayed doxycycline from £10 per week on 23 July 2026, but the exact provider and inclusions must be rechecked before publication.
Can you buy malaria tablets over the counter in the UK?
It depends on the product and traveller. Some atovaquone/proguanil products may be supplied by a pharmacist to eligible adults without a prescription after assessment. Doxycycline and mefloquine normally require prescription or an appropriate clinical supply route.
Is generic atovaquone/proguanil the same as Malarone?
Malarone is a brand of atovaquone/proguanil. Generic products contain the same active ingredients and strengths when equivalent, but price, excipients, pack size and availability can differ. Suitability should be confirmed during an assessment.
When should I start malaria tablets?
Atovaquone/proguanil and doxycycline are usually started one to two days before entering a malaria-risk area. Mefloquine is usually started two to three weeks before travel to assess tolerability. Follow the instructions for the exact medicine supplied.
Do I need malaria tablets for Thailand?
Not for every itinerary. Malaria risk in Thailand is concentrated in particular rural forested border areas, while several major cities and islands are listed as having no malaria risk. The exact route and personal risk factors must be checked.
Are malaria tablets 100% effective?
No. Correctly taken tablets substantially reduce risk when appropriate for the destination, but no option provides complete protection. Mosquito-bite prevention and urgent assessment of fever remain essential.
Can I take malaria tablets during pregnancy?
Pregnancy increases the risk of severe malaria, and malaria-risk travel should be avoided where possible. When travel is essential, the medicine choice requires an individual specialist assessment. Doxycycline is generally avoided for prophylaxis in pregnancy.
What should I do if I have side effects?
Read the patient information leaflet and seek advice for persistent, severe or worrying effects. New psychiatric or neurological symptoms while taking mefloquine need prompt medical advice. Do not stop or switch medicines without checking how to maintain protection.
What should I do if I get a fever after travel?
Seek urgent medical advice and tell the healthcare professional that you have been in a malaria-risk area. Possible malaria can require a same-day blood test and should be considered for symptoms developing within a year of return, even if tablets were taken.
