Medicines for prevent or treat malaria include chloroquine, mefloquine, doxycycline and primaquine, states WebMD. A person should take these medicines when traveling to an area with malaria, to reduce the risk of infection.
Chloroquine is used to treat malaria infections caused by caused by P. malariae or P. ovale parasites, notes WebMD. A person should continue taking this medicine after leaving areas with these parasites, to prevent relapses of infection. Children below nine years and pregnant women should not take doxycycline, and people with depression, seizures and heart rhythm problems should not take mefloquine.
Patients normally take malaria medicine through the mouth, but if there are complications, they can get intravenous, or IV, medicines, reports WebMD. Since malaria parasites may develop resistance, malaria medicines may change.
