Currently, there is only 1 carbamate and less than 5 organophosphate insecticides available on the public health market for indoor residual spraying as alternatives to DDT and pyrethroids.

When laboratory services are not available, it may be necessary to administer a combination of drugs, including an amoebicidal drug to kill the parasite, and an antibiotic to treat any associated bacterial infection.
