The Centers for Disease Control and Prevention CDC cannot attest to the accuracy of a non-federal website. Doxycycline can be used for the prevention of malaria in travelers to malaria-endemic areas and is a good option for areas with chloroquine or multidrug-resistant P. falciparum. For prophylaxis, doxycycline is taken once daily beginning 1–2 days before travel, while in malarious areas, and for 4 weeks after leaving. The prevention of malaria in expatriates and long-term travellers is complex. The traveller's doctor needs to consider the destination, the nature of the travel, the effectiveness and potential adverse effects of antimalarial medication, and the general health of the traveller.

    The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

    Abstract. The development of chloroquine as an antimalarial drug and the subsequent evolution of drug-resistant Plasmodium strains had major impacts on global public health in the 20th century. In P. falciparum the cause of the most lethal human malaria, chloroquine resistance is linked to multiple mutations in PfCRT, a protein that likely functions as a transporter in the parasite’s.

It is also used with proguanil when chloroquine-resistant falciparum malaria is present.
