    Falciparum Discontinue in 6 months if improvement is inadequate Use in patients with psoriasis may precipitate a severe attack of psoriasis; use with caution Postmarketing cases of life-threatening and fatal cardiomyopathy reported with use of hydroxychloroquine as well as of chloroquine Irreversible retinal damage observed in some patients who had received hydroxychloroquine sulfate; significant risk factors for retinal damage include daily doses of hydroxychloroquine sulfate greater than 6.5 mg/kg (5 mg/kg base) of actual body weight, durations of use greater than five years, subnormal glomerular filtration, use of some concomitant drug products such as tamoxifen citrate and concurrent macular disease Ocular examination is recommended within first year of therapy; baseline exam should include: best corrected distance visual acuity (BCVA), an automated threshold visual field (VF) of the central 10 degrees (with retesting if an abnormality is noted), and spectral domain ocular coherence tomography (SD-OCT) For individuals with significant risk factors (daily dose of hydroxychloroquine sulfate 5.0 mg/kg base of actual body weight, subnormal glomerular filtration, use of tamoxifen citrate or concurrent macular disease) monitoring should include annual examinations which include BCVA, VF and SD-OCT; for individuals without significant risk factors, annual exams can usually be deferred until five years of treatment In individuals of Asian descent, retinal toxicity may first be noticed outside macula; in patients of Asian descent, it is recommended that visual field testing be performed in central 24 degrees instead of central 10 degrees Hydroxychloroquine should be discontinued if ocular toxicity is suspected and patient should be closely observed given that retinal changes (and visual disturbances) may progress even after cessation of therapy Hepatic disease or alcoholism Glucose-6-phosphate dehydrogenase (G6PD) deficiency is associated with hemolysis and renal impairment; use with caution Dermatologic reactions to hydroxychloroquine may occur Patients are prone to dermatitis outbreaks Signs or symptoms of cardiac compromise have appeared during acute and chronic treatment; clinical monitoring for signs and symptoms of cardiomyopathy is advised, including use of appropriate diagnostic tools such as ECG to monitor patients for cardiomyopathy during therapy; if cardiotoxicity is suspected, prompt discontinuation may prevent life-threatening complications Not for administration with other drugs that have potential to prolong QT interval; hydroxychloroquine prolongs QT interval; ventricular arrhythmias and torsades de pointes reported in patients taking hydroxychloroquine Skeletal muscle myopathy or neuropathy leading to progressive weakness and atrophy of proximal muscle groups, depressed tendon reflexes, and abnormal nerve conduction, reported; muscle and nerve biopsies have been associated with curvilinear bodies and muscle fiber atrophy with vacuolar changes; assess muscle strength and deep tendon reflexes periodically in patients on long-term therapy Suicidal behavior rarely reported in patients treated with hydroxychloroquine Hematologic reactions (including aplastic anemia) and agranulocytosis may occur May exacerbate heart failure Shown to cause severe hypoglycemia including loss of consciousness that could be life threatening in patients treated with or without antidiabetic medications; warn patients about risk of hypoglycemia and associated clinical signs and symptoms; patients presenting with clinical symptoms suggestive of hypoglycemia during treatment should have their blood glucose checked and treatment reviewed as necessary A reduction in dosage may be necessary in patients with hepatic or renal disease, as well as in those taking medicines known to affect these organs Use with caution in patients with hepatic disease or alcoholism or in conjunction with known hepatotoxic drugs Consider discontinuing therapy if any severe blood disorder such as aplastic anemia, agranulocytosis, leukopenia, or thrombocytopenia, which is not attributable to the disease under treatment appears; perform periodic blood cell counts if patients are given prolonged therapy Pregnancy category: C Lactation: Drug is concentrated in breast milk (American Academy of Pediatrics committee states that it is compatible with nursing) A: Generally acceptable. Contact the applicable plan provider for the most current information. Controlled studies in pregnant women show no evidence of fetal risk.

    Usual Adult Dose for Malaria Prophylaxis. Suppression 400 mg 310 mg base orally on the same day every week Comments-Suppressive therapy should begin 2 weeks prior to exposure; however, failing this, an initial dose of 800 mg 620 mg base may be taken in 2 divided doses 6 hours apart. Aims Quinine is often used to prevent muscle cramps in patients with chronic renal failure. A standard dose of 300 mg at bedtime is usually recommended, but little is known about the pharmacokinetics of quinine in the presence of renal failure. Background and objectives Hydroxychloroquine is widely used in patients with rheumatoid arthritis. However, large-scale studies examining the long-term effects of hydroxychloroquine on the development of kidney disease in patients with rheumatoid arthritis are lacking. We aimed to assess the long-term association of hydroxychloroquine use with the risk of developing CKD in this population.

    Overdose symptoms include convulsions, drowsiness, headache, heart problems or heart failure, difficulty breathing and vision problems. Pharmacology Pharmacokinetics. Hydroxychloroquine has similar pharmacokinetics to chloroquine, with rapid gastrointestinal absorption and elimination by the kidneys. Background Acute kidney injury AKI still remains an unresolved problem in pharmacotherapy and renal inflammation is a major factor in its development. Chloroquine, a well-known antimalarial drug, posses pleitropic effects as well antiinflammatory, anticoagulant and vascular actions. The effects of chloroquine on renal function may involve significant increase in urine flow rate, glomerular. Drug Prescribing in Renal Failure Dosing Guidelines for Adults.
