Information in these tables is updated regularly.4. Several medications are available for chemoprophylaxis. When deciding which drug to use, consider specific itinerary, length of trip, cost of drug, previous adverse reactions to antimalarials, drug allergies, and current medical history. Hydroxychloroquine sulfate coupon Plaquenil 200 mg indications Chloroquine cocktail Approved indication For acute attacks of malaria due to P vivax, P malariae, P ovale, and susceptible strains of P falciparum CDC Recommendations Chloroquine-sensitive uncomplicated malaria Plasmodium species or species not identified 600 mg base 1 g salt orally at once, followed by 300 mg base 500 mg salt orally at 6, 24, and 48 hours Falciparum malaria is endemic without evidence of chloroquine CQ resistance 3, 6 – 8. Even though Haiti has had no comprehensive national malaria control program for 20 years 9, several reports have found no evidence of CQ resistance in Haiti 3, 6 – 8. Molecular characterization For some drugs chloroquine, sulfadoxine-pyrimethamine and similar drugs, atovaquone, molecular markers have been identified that confer resistance. Molecular techniques, such as PCR or gene sequencing can identify these markers in blood taken from malaria-infected patients. This risk estimate is based largely on cases occurring in US military personnel who travel for extended periods of time with unique itineraries that likely do not reflect the risk for the average US traveler.6. All travelers should seek medical attention in the event of fever during or after return from travel to areas with malaria.5.

Patients infected with a resistant strain of plasmodia as shown by the fact that normally adequate doses have failed to prevent or cure clinical malaria or parasitemia should be treated with another form of antimalarial therapy.

The clinical usefulness of chloroquine, and in some recent cases of quinine as well, has been much reduced by the evolution and spread of chloroquine resistant malaria parasites. The mechanism of resistance involves a reduced accumulation of the drug, although again the mechanism involved is controversial. Chloroquine-resistant P. falciparum first developed independently in three to four areas in Southeast Asia, Oceania, and South America in the late 1950s and early 1960s. Since then, chloroquine resistance has spread to nearly all areas of the world where falciparum malaria is transmitted. Drug-resistant malaria is increasing, and novel strategies to monitor for resistance are needed. Over 50 million persons from the industrialized world visit malaria-endemic countries annually, and record numbers of imported malaria cases are being reported in North America and Europe first well-documented cases of chloroquine-resistant and sulfadoxine-pyrimethamine SP–resistant.
