About atovaquone and proguanil
How to take atovaquone and proguanil
Take 1 atovaquone and proguanil tablet at the same time each day after having food or a milky drink.
- Start 1 or 2 days before travelling to a malarial area
- Continue each day during your stay
- Keep going for 7 more days after you leave and are in a malaria-free area
You need to finish taking all of the tablets you’ve been prescribed. Do not stop taking your atovaquone and proguanil tablets unless:
- a doctor or pharmacist tells you to
- you experience side effects that make you feel unwell
If you take an atovaquone and proguanil tablet and vomit within 1 hour, you’ll need to take another tablet. If it’s been more than 1 hour since you took your last tablet, you do not need to take another tablet.
If you forget to take a tablet, take it as soon as you remember. Then continue your course as usual. You do not need to take any extra atovaquone and proguanil tablets.
The patient information leaflet in your box of atovaquone and proguanil tablets has more details.
Atovaquone and proguanil is an antimalarial medicine that you can use to protect yourself against malaria.
Malaria is a disease caused by a parasite that mosquitoes carry. When a mosquito bites you it can pass the parasite into your bloodstream. Atovaquone and proguanil helps to protect you from a malaria infection by stopping the parasite from multiplying in your body.
Even if you take atovaquone and proguanil, you should still protect yourself from mosquito bites by:
- wearing loose clothes with long sleeves and long socks with closed shoes
- spraying bare skin with a high strength insect repellent, such as 50% DEET
- using mosquito nets over your bed and windows
- using plug-in mosquito repellents
- avoiding wet places that mosquitoes often breed in, like swamps, lakes or ponds
Atovaquone and proguanil work by killing the parasite (Plasmodium falciparum) that causes malaria. The parasite gets into your body when an infected mosquito bites you. The parasite travels through your bloodstream to the liver, where it multiplies and then goes back into the blood and into red blood cells. As the parasites grow in the red blood cells the cells burst, which causes the symptoms of malaria such as fever, chills and sweating.
Atovaquone and proguanil stop the malarial parasite from multiplying in your body.
Malarial parasites can become resistant over time to antimalarials. There’s less resistance to atovaquone and proguanil, so they’re effective for most places you may travel to.
