What are malaria pills?
Malaria pills — also called antimalarial tablets or malaria prophylaxis — are prescription medicines taken before, during and after travel to a malaria-risk area. They don't stop you being bitten. They stop the malaria parasite from multiplying in your body if an infected mosquito does bite you.
Do you need a prescription for malaria pills in Singapore?
Yes. Malaria pills are prescription-only medicines in Singapore. A doctor must assess your destination, itinerary, medical history and any other medications before prescribing, so you cannot buy them over the counter.
Can a GP prescribe malaria tablets?
Yes. Our GPs prescribe antimalarials after a short travel consultation, in which we review where you're going, how long you'll be there, how rural your itinerary is, and your medical history.
Is there a malaria vaccine?
Not for travellers. Malaria vaccines (RTS,S and R21) are used in routine childhood immunisation in some malaria-endemic African countries, but they are not available or recommended for travellers. For travel, malaria prevention relies on antimalarial tablets plus bite prevention.
Which countries require malaria pills?
Malaria risk is present in much of sub-Saharan Africa, parts of South and Southeast Asia (including rural Indonesia, Myanmar, Cambodia, Laos and East Malaysia), the Amazon basin in South America, and some Pacific Islands such as Papua New Guinea. Risk varies by region, season and how rural your trip is — our doctors will assess your exact itinerary.
How soon before travel should I start malaria pills?
It depends on which antimalarial you're prescribed — typically 1–2 days before for atovaquone-proguanil and doxycycline, and up to 2–3 weeks before for mefloquine. Come and see us around 4–6 weeks before you fly so there's time to start the right course, and to get any travel vaccines.
When do I stop taking them?
Not on the day you land home. The course continues after you return — typically 7 days for atovaquone-proguanil and 4 weeks for doxycycline and mefloquine — to clear any parasites still incubating. Stopping early is one of the most common reasons malaria prophylaxis fails.
What if I miss a dose or vomit after taking it?
If you remember a missed dose within a few hours, take it. If it's nearly time for the next dose, skip it — don't double up. If you vomit shortly after taking a tablet, you may need to repeat the dose. Missing doses reduces your protection, so take it at the same time each day and check with us if you're unsure.
What are the side effects of malaria pills?
Most people tolerate them well. Common effects include mild stomach upset, nausea, headache or dizziness; doxycycline can increase sun sensitivity; mefloquine may cause vivid dreams or mood changes. Serious reactions are uncommon. Seek medical attention promptly if you develop a rash, swelling, breathing difficulty or significant mood changes.
Who should not take malaria pills?
Certain antimalarials are unsuitable in pregnancy or breastfeeding, in young children, in people with kidney impairment, epilepsy, or some mental health conditions, and with certain other medications. Tell your doctor your full medical history so a safe option can be chosen for you.
Are malaria pills 100% effective?
No antimalarial is completely effective, which is why bite prevention still matters. Taken correctly alongside repellent, covered clothing and a treated bed net, malaria pills greatly reduce your risk of serious illness.
How much do malaria pills cost in Singapore?
Antimalarials are priced per tablet, so your total depends on which medicine you're prescribed and how long your trip is — the course continues for days or weeks after you return. A consultation fee also applies. Contact us for current pricing before you travel.
What if I get a fever after travelling?
Malaria can appear weeks or even months after you return, and can occur even if you took your tablets. Any fever during or after travel to a malaria area is a medical emergency until proven otherwise. See a doctor promptly and tell them exactly where you travelled.
Do I need travel vaccines as well?
Often, yes. Malaria is prevented with tablets, not a vaccine, but malaria-risk destinations frequently also call for travel vaccines such as typhoid, hepatitis A, yellow fever or Japanese encephalitis. We can plan your malaria prevention and travel vaccines in a single consultation.
