What it is

Atovaquone with proguanil is a combination antimalarial that attacks the parasite at two points in its life cycle — atovaquone disrupts its mitochondria, proguanil blocks folate metabolism. Together they are more effective than either alone.

Its practical advantage is the short tail: it acts against the parasite in the liver, so it only needs continuing for 7 days after leaving a malarial area, rather than the 4 weeks required by doxycycline and mefloquine.

It is generally the best-tolerated option, and correspondingly the most expensive.

What it is used for

  • Preventing malaria — the main use
  • Treating uncomplicated falciparum malaria, at higher doses and under specialist care

Which antimalarial is right depends entirely on where you are going, since resistance patterns differ by region. That is a country-by-country decision, not a general one.

How to take it

  • One tablet daily, at the same time each day
  • Start 1 to 2 days before entering the malarial area
  • Continue every day while there
  • Continue for 7 days after leaving
  • Take with food or a milky drink — absorption is roughly doubled, and this materially affects whether it works

If you vomit

Vomiting within an hour of the dose means taking another one. A dose that did not stay down is a dose not taken.

The part that matters at least as much

No antimalarial is fully protective, and bite avoidance is not optional:

  • DEET 50% repellent on exposed skin, reapplied as directed — apply sunscreen first, repellent second
  • An insecticide-treated bed net where rooms are not properly screened or air-conditioned
  • Cover up between dusk and dawn, when the malaria mosquito bites

Side effects

Generally the best tolerated of the antimalarials.

  • Abdominal pain, nausea, diarrhoea
  • Headache
  • Mouth ulcers
  • Vivid dreams, occasionally
  • Rash, itching

Taking it with food substantially reduces the stomach upset, as well as improving absorption.

Uncommon: liver enzyme changes, low blood counts, hair loss.

Unlike mefloquine, it very rarely causes significant neuropsychiatric effects — which is one of the main reasons people choose it.

Not suitable if

  • You have severe kidney impairment — it is not recommended below an eGFR of 30
  • You have had a reaction to atovaquone or proguanil
  • You are breastfeeding an infant under 5kg
  • You are pregnant — generally avoided, and pregnancy is a strong reason to reconsider travel to a high-risk malarial area at all

Caution in severe liver impairment, and in anyone who has had a splenectomy — which markedly increases the severity of malaria.

Interactions and monitoring

  • Rifampicin and rifabutin — substantially reduce atovaquone levels; the combination should be avoided
  • Metoclopramide — reduces absorption
  • Tetracyclines — reduce atovaquone levels
  • Warfarin — proguanil may increase the anticoagulant effect; INR monitoring advised
  • Efavirenz and some protease inhibitors — reduced levels

No routine monitoring for a standard travel course in someone healthy.

Kidney function should be known before prescribing to anyone with kidney disease.

Can we prescribe this?

Yes, as part of a travel health consultation — because the choice of antimalarial depends on exactly where you are going, and that has to be assessed rather than assumed.

What the consultation covers:

  • Your specific itinerary — risk varies not just by country but by region, altitude and season
  • Which antimalarial suits you — atovaquone-proguanil, doxycycline and mefloquine differ in cost, dosing schedule and side effects, and the right answer is personal
  • Your other medicines and conditions, particularly kidney function
  • Bite avoidance, which prevents more malaria than any tablet
  • What to do if you become unwell — and this is the part people remember least

The most important thing we will tell you: any fever during travel to a malarial area, or within a year of returning, must be treated as possible malaria and assessed urgently. Falciparum malaria can kill within days, and delay is the main reason it does. Tell whoever sees you where you have been.

We do not administer travel vaccinations — those need a travel clinic. A prescription is never guaranteed. This page is information, not an offer to supply.

Cost and supply

Malaria prevention is not available on the NHS — it is self-pay in the UK regardless of where you get it.

Generic atovaquone-proguanil costs considerably less than branded Malarone, and is identical. Maloff Protect is available directly from pharmacies without a prescription for adults, after a pharmacist consultation, and for a straightforward trip that is often the cheapest route — we would say so rather than take a fee.

Comparing honestly on cost

  • Doxycycline is by far the cheapest option, but must be continued for 4 weeks after returning, and causes sun sensitivity
  • Atovaquone-proguanil is the most expensive per day, but for a short trip the 7-day tail means fewer total tablets — so for a two-week holiday the gap narrows considerably
  • For a long trip, doxycycline is substantially cheaper overall

Worth buying

DEET 50% repellent and a treated bed net cost little and prevent more malaria than any tablet.

Stopping or switching

Complete the full 7 days after leaving the malarial area. Stopping on the plane home is a genuine and dangerous mistake — the parasite can still be developing.

No tapering is needed.

If it does not suit you

  • Doxycycline — much cheaper, but 4 weeks after return, and causes sun sensitivity and thrush
  • Mefloquine — weekly rather than daily, but with well-documented neuropsychiatric effects. Not suitable with a history of depression, anxiety or epilepsy
  • Chloroquine and proguanil — now of limited use because of widespread resistance

The rule that matters most

Any fever during or after travel to a malarial area — up to a year afterwards — needs urgent assessment and a malaria test.

Do not assume prophylaxis has protected you. No antimalarial is completely effective, and treating malaria as flu is how people die of it.

Common questions

Why do I only take it for 7 days after I get back?

Because it acts on the parasite in the liver as well as the blood. Doxycycline and mefloquine do not, which is why they need 4 weeks.

Do I have to take it with food?

Yes — food or a milky drink roughly doubles absorption. Taking it on an empty stomach genuinely reduces how well it protects you.

Is it worth the extra cost over doxycycline?

For a short trip, often yes — better tolerated, no sun sensitivity, and a much shorter course after returning. For a long trip, doxycycline is considerably cheaper overall.

Can I get it without a prescription?

Yes — Maloff Protect is available from pharmacies for adults after a pharmacist consultation. For a straightforward trip that is often the quickest and cheapest route.

Does it guarantee I will not get malaria?

No. No antimalarial is completely protective, which is why bite avoidance matters just as much. Repellent, covered skin after dusk, and a treated net.

What if I get a fever after I come home?

Seek urgent medical assessment and say where you have been — any fever up to a year after travel. Falciparum malaria can kill within days, and delayed diagnosis is the usual reason.

Can I take it in pregnancy?

It is generally avoided. More importantly, pregnancy is a strong reason to reconsider travelling to a high-risk malarial area at all — malaria in pregnancy is considerably more dangerous.

Questions about our service

How quickly can I be seen?

Same-day access is usually available, from 6am to 10pm, seven days a week. You choose a time that suits you rather than waiting on hold at 8am.

Will I see the same doctor each time?

Yes. Care is led personally by Dr Mohammad Khan, so you are not passed between clinicians. Continuity is the point of a small practice: someone who knows your history and is listening attentively rather than working through a checklist.

Can you see my NHS records?

Yes, with your consent. We can access your Summary Care Record during the consultation, so your current medications, allergies and significant history are in the room. That means fewer questions you have already answered elsewhere, and safer prescribing.

Are you trying to replace my NHS GP?

No. We are not here to replace GPs, only to support them. Your NHS practice remains responsible for your ongoing care, and with your consent we write to them after the consultation. We are useful when you need to be seen sooner, or want more time than a standard appointment allows.

What is included in the appointment?

Twenty unhurried minutes and a comprehensive assessment. A written treatment plan is included, along with any prescription, sick note or referral letter arising from the consultation, at no extra charge.

How much does it cost?

£40 for 20 minutes, self-pay. Membership is optional and never required. Priced for fairness, because we are not here to charge extortionate amounts for access to a doctor.

What does “treatable online” actually mean?

It means the diagnosis can usually be made from your history and photographs, and that treatment can be arranged safely without examining you. Where a condition is not marked treatable online, it is because examination is the diagnosis — listening to a chest, feeling an abdomen, examining an ear or a joint — or because a procedure or device is needed.

Can you prescribe antibiotics?

Yes, where there is a genuine bacterial infection — cellulitis, impetigo, bacterial urine infections, confirmed strep throat. We will also frequently tell you that you do not need one. Most sore throats, coughs, colds and earaches are viral, and an antibiotic gives you the side effects with none of the benefit.

What if the GP cannot help with what I need?

If your problem turns out to be genuinely outside what we can do remotely, the doctor will tell you straight away, point you to the right service, and refund your fee in full. We would rather do that than fill twenty minutes to justify the charge.

What should I do in an emergency?

Call 999 or go to A&E — do not book an online appointment and do not wait for a reply to an email. For urgent problems that are not emergencies, NHS 111 is available 24 hours a day, online or by phone, and can direct you to the right service.
