Quick Answer
Choosing the right antimalarial medication depends on your destination, malaria risk level, trip length, medical history, age, pregnancy status, other medicines and how soon you travel. Common options include atovaquone/proguanil, doxycycline and mefloquine. A travel clinic can recommend the most suitable option and explain mosquito-bite prevention.
Introduction
Malaria is a serious infection spread by infected mosquitoes in parts of Africa, Asia, Central and South America, the Middle East and Oceania. If you are travelling to a malaria-risk area, choosing the right antimalarial medication is an important part of your travel-health planning.
There is no single “best” malaria tablet for every traveller. The right choice depends on where you are going, when you are travelling, how long you will stay and whether the medicine is suitable for your health. Hemel Hempstead Travel Clinic provides Antimalarial Protection and personalised travel-health advice for local travellers.
Key Takeaways
- Antimalarial choice depends on destination and resistance patterns.
- Some tablets start 1–2 days before travel, while others need longer.
- You must continue tablets after leaving the malaria-risk area.
- Medical history and current medicines can affect the safest choice.
- Mosquito-bite prevention is still essential.
- Buy antimalarials from a trusted UK source.
- Seek urgent help if malaria symptoms appear during or after travel.
What Are Antimalarial Medications?
Antimalarial medications are tablets used to reduce the risk of malaria in travellers.
They do not replace bite prevention, but they can significantly lower your risk when taken correctly. Your clinician may recommend tablets if your destination, route and activities place you at risk.
Common options include:
- Atovaquone/proguanil
- Doxycycline
- Mefloquine
- Chloroquine, only for selected regions where suitable
How Do You Choose the Right Antimalarial?
The right antimalarial is chosen after reviewing your destination, health and travel plans.
A clinician will usually consider:
- Country and exact region
- Rural or urban travel
- Season and mosquito exposure
- Trip length
- Age and weight
- Pregnancy or breastfeeding
- Medical conditions
- Current medicines
- Previous side effects
- How soon you travel
This is why travellers should avoid choosing tablets only by price or online reviews.
Antimalarial Options Compared
Different malaria tablets have different schedules, benefits and cautions.
Medication | Common Use Point | Key Consideration |
Atovaquone/proguanil | Often used for shorter trips | Usually started shortly before travel and continued briefly after leaving risk area |
Doxycycline | Often used for longer or budget-conscious travel | Daily tablet; may increase sun sensitivity |
Mefloquine | Weekly option for some travellers | Must be checked carefully for suitability |
Chloroquine | Used only where appropriate | Not suitable for many regions due to resistance |
Your final choice should be based on professional advice, not a general comparison table.
When Should You Start Antimalarial Tablets?
Start timing depends on the medication prescribed.
Some antimalarial tablets need to be started only 1–2 days before entering the malaria-risk area. Others may need to start 1–3 weeks before travel. You may also need to continue them for 1–4 weeks after leaving the risk area, depending on the medicine.
Booking early gives you more options and helps avoid last-minute mistakes.
Why Is Mosquito-Bite Prevention Still Important?
Mosquito-bite prevention is essential because tablets do not offer complete protection.
Travellers should use insect repellent, wear long sleeves and trousers in the evening, sleep in screened or air-conditioned rooms where possible and use insecticide-treated mosquito nets where needed.
These steps also help reduce the risk of other mosquito-borne infections.
Who Needs Extra Care When Choosing Antimalarials?
Some travellers need more careful antimalarial advice because malaria may be more serious or medicine choice may be limited.
This includes:
- Pregnant travellers
- Young children
- Adults over 65
- People with weak immune systems
- People without a spleen
- Travellers taking regular medication
- People with previous antimalarial side effects
- Long-stay travellers
If you are in one of these groups, book travel-health advice early.
Common Mistakes to Avoid
The most common mistake is waiting until the last minute.
Other mistakes include stopping tablets too early, buying medicines from unreliable sources, forgetting doses, assuming city travel is always risk-free or using leftover tablets from a previous trip.
If you become unwell with fever, chills, headache, sweating, vomiting or flu-like symptoms during or after travel, seek urgent medical advice and mention your travel history.

Common Misconceptions
One common misconception is that all malaria tablets are the same. In reality, different medicines suit different destinations and travellers.
Another myth is that antimalarials mean mosquito precautions are unnecessary. Bite prevention is still important.
Some travellers also think malaria symptoms always appear immediately. Symptoms can appear after travel, so recent travel history should always be mentioned when seeking medical help.
