    Acute poisonings involving chloroquine are common in sharp contrast to those involving proguanil, another antimalarial drug. A 39-year-old woman ingested a combination of 11.2 g chloroquine and 22.4 g proguanil i.e. 112 tablets of the commercial product Savarine. One hundred sixty-seven consecutive patients with acute chloroquine overdose admitted to our toxicology ICU. The mean amount ingested by history was 4.5 +2- 2.8 g. and 43 26% of 167 patients ingested 5 g. The mean blood chloroquine concentration on admission was 20.5 +/- 13.4 mumol/L. The only study in humans looking at severe chloroquine overdoses was done by Riou et al in 1988. 12 The criteria for severe chloroquine poisoning was an ingestion of 5 grams, which a retrospective study had determined to be an accurate predictor of a fatal outcome. They treated 11 prospective chloroquine overdose patients with immediate mechanical ventilation, epinephrine, and diazepam at 2 mg/kg over 30 minutes, then 1 to 2 mg/kg/day.

    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.

Jul 30, 2019 The usefulness of hypokalemia as an indicator in the evaluation of chloroquine toxicity was studied in a retrospective series of 191 acute chloroquine poisonings. Results indicated that the risk of severe poisoning and death are proportional to the degree of hypokalemia.
