There is no single antimalarial tablet that is best for every traveller. Malarone (atovaquone/proguanil), doxycycline and Lariam (mefloquine) can all be recommended for some malaria-risk destinations, but the right choice depends on the country and region, resistance patterns, trip length, medical history, age, pregnancy status, other medicines and how reliably you can follow the dosing schedule.
For many short trips, Malarone is convenient because it is started shortly before travel and continued for only seven days after leaving the risk area. Doxycycline is often a lower-cost daily option, but it must normally continue for four weeks after leaving and can cause sun sensitivity or irritation of the food pipe. Lariam is taken weekly, yet its important neuropsychiatric cautions mean it is unsuitable for many people and should be started early enough to assess tolerance.
The safest way to identify the best malaria tablets for your journey is to check the current destination recommendation and complete a clinical assessment. Medicina's anti-malaria travel-health service currently provides access to verified options including Malarone and doxycycline, subject to prescriber approval.
At a glance: which antimalarial may suit which traveller?
A useful starting point is not "which drug is strongest?" but "which licensed option fits the destination and the traveller?" The following summary is general and does not replace a destination-specific recommendation.
Malarone may be attractive for a short trip or a last-minute departure because the course usually begins one to two days before entering the risk area and continues for seven days after leaving. It is taken daily with food or a milky drink. It may not be suitable in severe kidney impairment and requires individual review in pregnancy or breastfeeding.
Doxycycline may suit travellers who can manage a daily tablet and a four-week post-travel course. It can also offer protection against some other infections, but it can increase sensitivity to sunlight and may irritate the oesophagus if taken without enough water or immediately before lying down. It is generally avoided in pregnancy and is not normally used for malaria prevention in younger children.
Lariam may suit some travellers who prefer weekly dosing or need an option considered in certain pregnancy circumstances. However, it must not be used in people with particular psychiatric histories or seizure disorders, and treatment should be stopped and urgent clinical advice sought if important neuropsychiatric symptoms occur. Its long lead-in period also makes it less suitable for late bookings.
Why destination advice comes before brand preference
Malaria risk can differ within the same country by region, altitude, season and itinerary. Some destinations require bite-avoidance measures only, while others require chemoprophylaxis. In high-risk areas, official UK advice may list atovaquone/proguanil, doxycycline or mefloquine as alternatives, but that does not mean every option is equally suitable for every traveller.
A clinician should consider where you will sleep, rural or urban travel, length of stay, stopovers, previous reactions, medical conditions and current medicines. Advice can change when resistance patterns or local transmission change, so an old prescription or a friend's recommendation should not be reused without review.
For planning, use a current destination page and then read Medicina's country-specific malaria tablet guide once that supporting article has been clinically reviewed and published.
Malarone: benefits, schedule and main cautions
Malarone combines atovaquone and proguanil. For malaria prevention, adult dosing is generally once daily, beginning one to two days before entering a malaria-risk area, continuing throughout exposure and for seven days after leaving. The exact strength and dose depend on age and weight, and the medicine should be taken with food or a milky drink to support absorption.
Its shorter post-travel course is a major practical advantage. This can reduce the number of tablets needed after a short holiday and may make adherence easier for people who struggle to continue treatment for a month after returning home.
Commonly discussed drawbacks include gastrointestinal effects, headache and a higher total course cost than some generic doxycycline regimens. It may not be suitable for people with severe renal impairment, and pregnancy or breastfeeding requires individual assessment. Vomiting or diarrhoea can affect absorption and may require advice.
Travellers considering this option can review the verified Malarone malaria-prevention page before completing the clinical consultation.
Doxycycline: benefits, schedule and main cautions
Doxycycline is an antibiotic that is also used for malaria prevention. A typical adult prophylaxis schedule is 100mg once daily, started one to two days before travel, taken every day in the risk area and continued for four weeks after leaving. The prescriber will confirm whether it is appropriate and which formulation to use.
It may be a practical option for longer trips or travellers who prefer a generic medicine. The main adherence challenge is the extended four-week post-travel period. Missing doses can reduce protection, so daily reminders and enough tablets for the whole course are important.
Doxycycline can make skin more sensitive to sunlight. Travellers should use strong sun protection and follow the supplied leaflet. It should be swallowed with plenty of water while sitting or standing, and the person should not lie down immediately afterwards, because it can irritate the throat and oesophagus. It can interact with antacids and supplements containing iron, calcium, magnesium or zinc when taken too close together.
It is generally avoided during pregnancy. Suitability for children depends on age, weight, indication and current guidance, so a prescriber must assess younger travellers individually.
Medicina's verified doxycycline malaria tablets page explains the online assessment and supply route.
Lariam (mefloquine): benefits, schedule and main cautions
Lariam is a brand of mefloquine. For prevention it is normally taken once weekly, beginning before travel, throughout the risk period and for four weeks after leaving. Starting two to three weeks before departure is commonly advised so that tolerance can be assessed and the weekly routine established.
Weekly dosing may appeal to travellers who find daily tablets difficult. Mefloquine can also be considered in some circumstances where other options are unsuitable, including certain pregnancy situations when travel to a high-risk area cannot be avoided and specialist advice supports its use.
The major limitation is its neuropsychiatric safety profile. Lariam is contraindicated in people with current or previous depression, generalised anxiety disorder, psychosis, schizophrenia, suicide attempts or other serious psychiatric disorders, and in people with a history of convulsions. Symptoms such as nightmares, acute anxiety, depression, restlessness or confusion during prophylaxis require prompt medical assessment and may require the medicine to be stopped and replaced.
Medicina Pharmacy does not currently display a verified Lariam product page in the travel-health range checked for this article. The medicine is therefore discussed for balanced comparison, not presented as a product currently supplied by Medicina.
Malarone vs doxycycline vs Lariam: key decision factors
1. How soon are you travelling?
Malarone and doxycycline are usually started one to two days before entering a risk area, so they may be considered for a relatively late consultation if clinically suitable. Lariam needs an earlier start, commonly two to three weeks before travel, which makes advance planning particularly important.
2. How long can you continue after the trip?
Malarone continues for seven days after leaving the malaria area. Doxycycline and Lariam normally continue for four weeks. A shorter course is not automatically better, but it may improve adherence for some travellers.
3. Can you manage daily or weekly dosing?
Malarone and doxycycline are daily medicines. Lariam is weekly. A medicine only protects properly when it is taken according to the prescribed schedule, so the most convenient option is the one you can take reliably without missing doses.
4. What side effects matter most for your itinerary?
Doxycycline's sun sensitivity may be especially relevant for beach holidays, outdoor work or high-altitude itineraries with intense ultraviolet exposure. Malarone's gastrointestinal effects may matter if the traveller already has digestive problems. Lariam's psychiatric and neurological cautions are decisive rather than minor inconveniences.
5. Are pregnancy, kidney problems or other conditions relevant?
Pregnancy, breastfeeding, kidney function, psychiatric history, seizures, age, weight and medicine interactions can change the available choices. This is why a consultation is required even when the destination allows several options.
Are the best anti malaria tablets always the most expensive?
No. Price does not determine clinical suitability or protection. Total cost depends on the medicine, trip length, lead-in and post-travel days, pack configuration and provider. A short Malarone course may require fewer post-travel tablets, while doxycycline may have a lower tablet cost but a longer course. Lariam's weekly schedule changes the number of doses, but safety suitability remains the first filter.
Compare the total prescribed course rather than a "from" price or price per tablet. Do not buy fewer tablets than required for the complete itinerary, and do not choose a medicine solely because it appears cheaper.
No antimalarial replaces mosquito-bite prevention
Antimalarial tablets reduce risk but do not provide complete protection. Travellers should also use insect repellent, wear covering clothing when practical, sleep in screened or air-conditioned rooms where available and use an insecticide-treated bed net when appropriate. Follow destination-specific advice.
Malaria can present after travel even when tablets were taken correctly. Fever, chills, sweats, headache, muscle aches or flu-like illness during travel or after returning require urgent medical advice. Tell the healthcare professional where and when you travelled. Malaria can be life-threatening and should not be self-diagnosed.
How to arrange antimalarial treatment online
Start by checking the malaria recommendation for every country and region on your itinerary. Then complete the online questionnaire with accurate information about dates, destinations, pregnancy possibility, allergies, kidney function, psychiatric history, seizures and all medicines or supplements.
A prescriber reviews the information and decides whether a medicine can be supplied. Completing the questionnaire does not guarantee a prescription. The recommended option may differ from the one you initially preferred, and some travellers may need advice from a specialist travel clinic or GP.
You can begin with Medicina Pharmacy's online travel-health consultation and review the current Anti-Malaria range before ordering.
Conclusion
The best malaria tablets are the option recommended for your exact destination and judged suitable for your health and itinerary. Malarone often offers the shortest post-travel course, doxycycline can be a practical daily alternative with a longer follow-on period, and Lariam offers weekly dosing but has important psychiatric and neurological restrictions.
Do not choose only by brand, price or dosing frequency. Check current destination guidance, allow enough time before departure and complete a clinical assessment. Continue mosquito-bite precautions because no antimalarial provides complete protection.

FAQs
Which are the best malaria tablets for most travellers?
There is no universal best option. The correct medicine depends on destination risk, resistance, medical history, pregnancy status, age, interactions, trip duration and ability to follow the full schedule.
Is Malarone better than doxycycline?
Malarone has a shorter post-travel course, while doxycycline may be a lower-cost option for some travellers. Either can be unsuitable because of medical conditions, side effects or interactions, so a prescriber must decide.
Is Lariam better because it is taken weekly?
Weekly dosing can be convenient, but Lariam has important neuropsychiatric contraindications and must be started well before travel. Convenience does not override safety.
How long do I take Malarone after leaving a malaria area?
Malarone is generally continued for seven days after leaving the risk area. Follow the exact prescription and leaflet because the course depends on the itinerary and traveller.
How long do I take doxycycline after travel?
Doxycycline for malaria prevention is generally continued for four weeks after leaving the risk area. Do not stop early unless a clinician instructs you to change treatment.
When should Lariam be started before travel?
Mefloquine is commonly started two to three weeks before entering the risk area so tolerance can be assessed. Seek destination-specific and prescriber advice early.
Can I change antimalarial tablets if I get side effects?
Do not switch or stop without clinical advice, because an alternative schedule may need to start immediately. Urgent neuropsychiatric symptoms with mefloquine require prompt medical assessment.
Do malaria tablets guarantee I will not get malaria?
No. They reduce risk but do not eliminate it. Use mosquito-bite precautions and seek urgent medical advice for a fever or flu-like illness during or after travel.
