Chloroquine-resistant P. vivax malaria was first identified in 1989 among Australians living in or traveling to Papua New Guinea. P. vivax resistance to chloroquine has also now been identified in Southeast Asia, Ethiopia, and Madagascar. Isolated reports have suggested chloroquine-resistance P. vivax in other countries and regions, but further evaluation is needed.

Recent laboratory and clinical studies have associated chloroquine resistance with point mutations in the gene pfcrt. However, direct proof of a causal relationship has remained elusive and most models have posited a multigenic basis of resistance. Although resistance to these drugs tends to be much less widespread geographically, in some areas of the world, the impact of multi-drug resistant malaria can be extensive. Has also developed resistance to nearly all of the other currently available antimalarial drugs, such as sulfadoxine/pyrimethamine, mefloquine, halofantrine, and quinine.

For treatment of acute attacks of malaria in adults, one dose is usually taken right away, followed by half the dose 6 to 8 hours later and then half the dose once a day for the next 2 days. For prevention and treatment of malaria in infants and children, the amount of chloroquine phosphate is based on the child's weight.
