Tell your doctor and pharmacist about all of your drugs (prescription or OTC, natural products, vitamins) and health problems.

Retinal toxicity hydroxychloroquine Plaquenil retinopathy oct Plaquenil tylenol interaction Chloroquine is the most widely used drug against malaria, except for those cases caused by chloroquine resistant Plasmodium falciparum. Although the mechanism of action is not fully understood, chloroquine is shown to inhibit the parasitic enzyme heme polymerase that converts the toxic heme into non-toxic hemazoin, thereby resulting in the accumulation of toxic heme within the parasite. Since the 1970s, the border area between Cambodia and Thailand has been the epicentre of emerging malaria drug resistance. This started with resistance to chloroquine, followed by resistance to sulfadoxine-pyrimethamine, then mefloquine, and currently there is an increasing failure rate of P. falciparum to artemisinin-based combination therapies CHLOROQUINE sulfate or phosphate oral Given that resistance of P. falciparum to chloroquine is widespread, this drug must not be used for the treatment of falciparum malaria in Africa, South America, Asia and Oceania. For all uses of chloroquine: WARNING/CAUTION: Even though it may be rare, some people may have very bad and sometimes deadly side effects when taking a drug. Do not start, stop, or change the dose of any drug without checking with your doctor.

Second, Cambodia seems to be a harbinger of malaria resistance. Resistant malaria strains frequently crop up in Cambodia before spreading to the rest of the world.

Plasmodium falciparum resistant to Chloroquine in Cambodia. The authors report the discovery of a strain of Plasmodium falciparum, resistant to chloroquine, from Paulin, in Cambodia; 3 infections were contracted in October 1962. Attacks occurred after chloroquine prophylaxis and after normal therapeutic regimens. Did medicated salt hasten the spread of chloroquine resistance in Plasmodium falciparum? D, Payne With acknowledged di~culties in achieving satisfactory compliance rates for the large- scale delivery of many antiparasitic drugs, the use of medicated salt has often been seen as a useful way to improve the level of treatment in target populations. However, misuse of antimalarial drugs, such as in the form of medicated salt, and widespread availability of low quality medicines lead to the emergence of drug resistance. Chloroquine resistance in Plasmodium falciparum appeared almost at the same time in Thailand in Southeast Asia SEA in 1957 and in Colombia in South America in 1959.
