Chloroquine can also induce cataract formation; however, no reports of hydroxychloroquine and cataract have been reported 1. Background The management and toxicokinetics of hydroxychloroquine overdose are poorly described. Case Report We report a case of an 18-year-old girl who ingested 20 g of hydroxychloroquine. She developed marked hypokalemia, hypotension, and ventricular tachyarrhythmias but survived with treatment including intubation, adrenaline infusion, high-dose diazepam, and aggressive potassium replacement. Mechanism of Toxicity. The mechanism of hydroxychloroquine retinal toxicity has yet to be fully elucidated. Studies have shown that the drug affects the metabolism of retinal cells and also binds to melanin in the RPE, which could explain the persistent toxicity after discontinuation of the medication. It is imperative that patients and physicians are aware of and watch for this drug’s ocular side effects. Retinal toxicity from hydroxychloroquine is rare, but even if the medication is discontinued, vision loss may be irreversible and may continue to progress.

Hydroxychloroquine is synthesised by adding a hydroxyl group to an N-ethyl group of chloroquine rendering it 2-4 times less toxic. 1 As hydroxychloroquine and chloroquine share similar structural and pharmacological properties, and there is relatively richer experience with chloroquine toxicity, most of the following discussions are based on studies of Find patient medical information for Hydroxychloroquine Oral on WebMD including its uses, side effects and safety, interactions, pictures, warnings and user ratings. Toxicokinetics Both chloroquine and hydroxychloroquine have excellent oral absorption and bioavailability. Both have a long and variable plasma elimination half-life because of a high volume of distribution, an extended mean residence time HCQ 1300 hours and CQ 900 hours and with about half the drug metabolites undergoing unmodified renal clearance.
