How It Works

Malarone is a combination medicine that stops the development of parasites in the blood that cause malaria.

To prevent malaria, adults need to take one tablet daily 1 to 2 days before entering an area where malaria is present, continue taking it daily throughout their stay, and then take it for 7 days after they return.

To treat malaria, adults can take a single daily dose of four tablets for 3 days in a row.

Dosages for children vary depending on body weight.

Why It Is Used

People take Malarone to prevent and treat uncomplicated malaria that is caused by Plasmodium (P). falciparum. Doctors also use Malarone to treat people with malaria in areas that have chloroquine-resistant or other resistant strains.

How Well It Works

Malarone appears to be effective in the prevention and treatment of malaria caused by P. falciparum, including infections acquired in areas with chloroquine-resistant strains.¹
