    Whats the dosage that causes plaquenil toxicity


    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.

    The pediatric weekly suppressive dosage is 5 mg/kg of body weight. The adult dose of Plaquenil to treat an acute attack of malaria is an initial dose of 800 mg followed by 400 mg in six to eight hours and 400 mg for two more days. To treat lupus erythematosus, the average adult dose is 400 mg once or twice daily. Plaquenil is a slow-acting drug, meaning that it can take up to 6 months to experience the full benefits of this medication, but it is possible for symptoms to improve in as few as 1 or 2 months. Plaquenil and other antimalarials are the key to controlling lupus long-term, and some lupus patients may be on Plaquenil for the rest of their lives. The usual dosage works for most people who take Plaquenil, but it is possible to increase or decrease the dose based on individual needs. It's important to watch for possible side effects and toxicity. For people who weigh less than 80 kg, a lower daily dose is prescribed, up to a maximum of 5 mg/kg of body weight.

    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.

Ventricular arrhythmias and torsade de pointes have been reported with the use of hydroxychloroquine. Citalopram causes dose-dependent QT interval prolongation. Malaria is spread by mosquitoes, which transmit the parasites that cause the infection, usually in tropical and subtropical parts of the world. Plaquenil is used to treat other types of infections.
