What Malarone is and what it is used for

Malarone belongs to a group of medicines called antimalarials. It
contains two active ingredients, atovaquone and proguanil
What Malarone is used for
Malarone has two uses:
■ to prevent malaria
■ to treat malaria
Dosage instructions for each use are in Section 3, How to take
Malaria is spread by the bite of an infected mosquito, which passes
the malaria parasite (Plasmodium falciparum) into the bloodstream.
Malarone prevents malaria by killing this parasite. For people who
are already infected with malaria, Malarone also kills these
Protect yourself from catching malaria
People of any age can get malaria. It is a serious disease, but is
As well as taking Malarone, it is very important that you also take
steps to avoid being bitten by mosquitoes.

Use insect repellent on exposed areas of the skin
Wear light coloured clothing that covers most of the body,
especially after sunset as this is the time when mosquitoes are
most active
Sleep in a screened room or under a mosquito net
impregnated with insecticide
Close windows and doors at sunset, if they are not screened
Consider using an insecticide (mats, spray, plug-ins) to clear
a room of insects or to deter mosquitoes from entering the room.

If you need further advice, talk to your doctor or pharmacist.
It is still possible to get malaria after taking the necessary
precautions. Some types of malaria infection take a long time to
cause symptoms, so the illness may not start until several days,
weeks or even months after returning from abroad.
See a doctor immediately if you get symptoms such as high
temperature, headache, shivering and tiredness after returning

What you need to know before you take Malarone

kg. There is another tablet strength to treat children who weigh

Tell your doctor or pharmacist if any of these applies to you.
Other medicines and Malarone
Tell your doctor or pharmacist if you are taking, have recently
taken, or might take any other medicines, including medicines
you’ve bought without a prescription.
Some medicines can affect the way Malarone works, or Malarone
itself can strengthen or weaken the effectiveness of other medicines
taken at the same time. These include:
■ metoclopramide, used to treat nausea and vomiting
■ the antibiotics, tetracycline, rifampicin and rifabutin
■ efavirenz or certain highly active protease-inhibitors used to
treat HIV
■ warfarin and other medicines that stop blood clotting
■ etoposide used to treat cancer.

Tell your doctor if you are taking any of these. Your doctor may
decide that Malarone isn’t suitable for you, or that you need
extra check ups while you’re taking it.
Remember to tell your doctor if you start taking any other
medicines while you’re taking Malarone.
Malarone with food and drink
Take Malarone with food or a milky drink, where possible. This
will increase the amount of Malarone your body can absorb, and
make your treatment more effective.
Pregnancy and breast-feeding
If you are pregnant, do not take Malarone unless your doctor
recommends it.
Ask your doctor or pharmacist for advice before taking Malarone
Do not breast-feed while taking Malarone, as the ingredients of

not drive, use machines or take part in activities where you may put
yourself or others at risk.
