Chloroquine is a medicine to prevent malaria, which is a life-threatening disease caused by mosquitoes. If you get malaria from a mosquito bite you can take Chloroquine as a treatment.
Chloroquine works by killing malarial parasites within your red blood cells and preventing them from multiplying and invading other red blood cells. Malarial parasites, known as plasmodium, are carried by mosquitoes. If you get a mosquito bite, the malarial parasite gets into your bloodstream. To prevent malaria, take Chloroquine a week before you travel, during your stay, and after you leave a malarial area as your doctor has instructed.
