Pattern of Retinopathy: Although the locus of toxic damage is parafoveal in many eyes, Asian patients often show an extramacular pattern of damage. Dose: We recommend a maximum daily HCQ use of 5.0 mg/kg real weight, which correlates better with risk than ideal weight. Tapering off plaquenil Malarone versus chloroquine Plaquenil for ccca 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. An overdose of chloroquine can be fatal, especially in children. Chloroquine overdose must be treated quickly. You may be told to induce vomiting right away at home, before transport to an emergency room. Ask the poison control center how to induce vomiting in the case of an overdose. Risk for toxicity is least with less than 6.5 mg/kg/day for hydroxychloroquine and 3 mg/kg/day for chloroquine. Patients are at low risk during the first 5 years of treatment. Cumulative use in excess of 250 grams increases the risk for toxic retinopathy. Other risk factors include obesity, kidney or liver disease, older age. Risk of Toxicity: The risk of toxicity is dependent on daily dose and duration of use. There are no similar demographic data for CQ, but dose comparisons in older literature suggest using 2.3 mg/kg real weight.

Post-exposure Chloroquine Prophylaxis COVID19. Hydroxychloroquine toxicity - EyeWiki. Treatment of Severe Chloroquine Poisoning NEJM. The mechanism of chloroquine and hydroxychloroquine toxicity is not well understood. Chloroquine has an affinity for pigmented melanin-containing structures, which may explain its toxic properties in the eye. Melanin serves as a free-radical stabilizer and can bind toxins, including retinotoxic drugs. Chloroquine is used to prevent or treat malaria caused by mosquito bites in countries where malaria is common. Malaria parasites can enter the body through these mosquito bites, and then live in body tissues such as red blood cells or the liver. Treatment of acute chloroquine poisoning a 5-year experience.
