    Hydroxychloroquine overdose toxicokinetics and management


    One such commonly used medication for dermatologic and rheumatologic inflammatory conditions is hydroxychloroquine (Plaquenil), a chloroquine derivative. It is used to treat many diseases including malaria, rheumatoid arthritis and systemic lupus erythematosus.

    Similarly, the management of patients with hydroxychloroquine overdoses is based on animal and human data for chloroquine toxicity which demonstrate improved outcomes with high dose diazepam, epinephrine and early intubation 1,2. Hydroxychloroquine Plaquenil, Sanofi-Aventis remains widely used in the treatment of various rheumatologic disorders. A small percentage of patients exposed to hydroxychloroquine will develop irreversible, and potentially progressive, retinal toxicity for which no effective treatment exists.

    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.

  3. 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.

    Abstract Hydroxychloroquine poisoning has rarely been reported in the literature, with only 18 cases being found on searching the literature. In this paper, we report a case that occurred in Hong Kong, and we make recommendations for emergency management of hydroxychloroquine overdose based on our and other's experience. Hydroxychloroquine – which has a similar toxicity profile – has largely superseded it for the treatment of rheumatoid arthritis. In overdose both chloroquine and hydroxychloroquine cause sodium channel blockade with primarily cardiovascular and central nervous system effects, as well as hypokalemia due to intracellular potassium shifts. Although hydroxychloroquine overdoses are very rare, life-threatening hypotension, conduction problems, and hypokalemia can occur within 30 minutes of ingestion. Symptoms are similar to chloroquine and treatment must be implemented quickly and should be modeled after experience with chloroquine overdoses.
