Abstract

Strains of falciparum malaria resistant to chloroquine and other antimalarials have become common in the tropics, including East and West Africa where most cases of falciparum malaria imported into Britain originate.¹ Mefloquine (Lariam – Roche) can now be used for malaria prophylaxis in travellers to these areas and to treat patients with falciparum malaria likely to be resistant to other antimalarials.
