Does plaquenil cause dark urine Should users of hydroxychloroquine take cholesterol-lowering medications SummaryLarge doses of chloroquine can cause poisoning. Our aim was to determine the possible relation between the plasma potassium concentration on admission with the severity of acute chloroquine poisoning and to assess the mechanism of chloroquine-induced conducted a retrospective study of 191 consecutive cases. The main data included the occurrence of vomiting before. Disease Entity.

End goals should be a narrow QRS 100ms and a pH 7.45 Abstract. Background The American Academy of Ophthalmology recommendations on screening for chloroquine CQ and hydroxychloroquine HCQ retinopathy are revised in light of new information about the prevalence of toxicity, risk factors, fundus distribution, and effectiveness of screening tools. Quinine and chloroquine poisoning are characterized by severe cardiovascular toxicity resulting from sodium and potassium channel blockade, leading to hypotension, shock, arrhythmias and cardiac arrest. Quinine poisoning can cause irreversible visual loss.
