Overdosage of HYDROXYCHLOROQUINE SULFATE
Information about signs, symptoms, and laboratory findings of acute ovedosage and the general principles of overdose treatment.10 OVERDOSAGE Hydroxychloroquine sulfate tablets overdosage symptoms have an onset within 1 to 3 hours of ingestion. The following have been reported with hydroxychloroquine sulfate tablets overdosage: • Cardiovascular toxicity, including QRS or QTc prolongation, ventricular tachycardia, ventricular fibrillation, torsade de pointes, atrioventricular block, cardiac arrest and death. • Life-threatening hypotension is common. • Severe hypokalemia secondary to an intracellular shift is common in severe toxicity. • Central nervous system (CNS) depression, seizures, visual disturbances, transient blindness, and coma may occur. Gastrointestinal decontamination procedures warrant consideration in patients that present within the first hour post-ingestion. If the level of consciousness rapidly deteriorates in severe poisoning, consider intubation before gastrointestinal decontamination procedures. Monitor plasma potassium levels and manage accordingly. Hemofiltration, hemodialysis, and hemoperfusion are not of benefit. Consider contacting a poison center (1-800-221-2222) or a medical toxicologist for overdosage management recommendations.
Adverse reactions
Information about undesirable effects, reasonably associated with use of the drug, that may occur as part of the pharmacological action of the drug or may be unpredictable in its occurrence. Adverse reactions include those that occur with the drug, and if applicable, with drugs in the same pharmacologically active and chemically related class. There is considerable variation in the listing of adverse reactions. They may be categorized by organ system, by severity of reaction, by frequency, by toxicological mechanism, or by a combination of these.6 ADVERSE REACTIONS The following adverse reactions are described in greater detail in other sections: • Cardiomyopathy and Ventricular Arrhythmias [ see Warnings and Precautions (5.1) ] • Retinal Toxicity [ see Warnings and Precautions (5. 2)] • Serious Skin Reactions [ see Warnings and Precautions (5.3)] • Worsening of Psoriasis [ see Warnings and Precautions (5.4) ] • Risks Associated with Use in Porphyria [ see Warnings and Precautions (5.5)] • Hematologic Toxicity [ see Warnings and Precautions (5.6) ] • Hemolytic Anemia Associated with G6PD [ see Warnings and Precautions (5.7) ] • Skeletal Muscle Myopathy or Neuropathy [ see Warnings and Precautions (5.8) ] • Neuropsychiatric Reactions Including Suicidality [ see Warnings and Precautions (5.9) ] • Hypoglycemia [ see Warnings and Precautions (5.10) ] The following adverse reactions have been identified during post-approval use of 4‑aminoquinoline drugs, including hydroxychloroquine sulfate tablets. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure: • Blood and lymphatic system disorders : Bone marrow depression, anemia, aplastic anemia, agranulocytosis, leukopenia, thrombocytopenia • Cardiac disorders: Cardiomyopathy, cardiac failure, QT-interval prolongation, ventricular tachycardia, torsades de pointes, atrioventricular block, bundle branch block, sick sinus syndrome, pulmonary hypertension • Ear and labyrinth disorders: Vertigo, tinnitus, nystagmus, sensorineural hearing loss • Eye disorders: Retinopathy, retinal pigmentation changes (typically bull’s eye appearance), visual field defects (paracentral scotomas), macular degeneration, corneal edema, corneal opacities, decreased dark adaptation • Gastrointestinal disorders: Nausea, vomiting, diarrhea, abdominal pain • General disorders: Fatigue • Hepatobiliary disorders: Abnormal liver function tests, fulminant hepatic failure • Immune system disorders: Urticaria, angioedema, bronchospasm • Metabolism and nutrition disorders: Anorexia, hypoglycemia, weight loss • Musculoskeletal and connective tissue disorders: Proximal myopathy, depressed tendon reflexes, abnormal nerve conduction • Nervous system disorders: Ataxia, dizziness, headache, seizure, extrapyramidal disorders (dystonia, dyskinesia, tremor) • Neuropsychiatric disorders: Affect/emotional lability, irritability, nervousness, psychosis, suicidal ideation, suicidal behavior, depression, hallucinations, anxiety, agitation, confusion, delusions, paranoia, mania and sleep disorders (insomnia, night terrors, nightmares) • Skin and subcutaneous tissue disorders: Alopecia, hair color changes, rash, pruritus, photosensitivity, psoriasis exacerbation, hyperpigmentation, exfoliative dermatitis, erythema multiforme, acute generalized exanthematous pustulosis, Drug Rash with Eosinophilia and Systemic Symptoms (DRESS syndrome), Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN) The most common adverse reactions reported are: nausea, vomiting, diarrhea, and abdominal pain.

HYDROXYCHLOROQUINE SULFATE Drug Interactions
Information about and practical guidance on preventing clinically significant drug/drug and drug/food interactions that may occur in people taking the drug.7 DRUG INTERACTIONS • Drugs Prolonging QT Interval and Other Arrhythmogenic Drugs. (7.1) • See FPI for more important drug interactions. (7) 7.1 Drugs Prolonging QT Interval and Other Arrhythmogenic Drugs Hydroxychloroquine sulfate tablets prolongs the QT interval. There may be an increased risk of inducing ventricular arrhythmias if hydroxychloroquine sulfate tablets is used concomitantly with other arrhythmogenic drugs. Therefore, hydroxychloroquine sulfate tablets are not recommended in patients taking other drugs that have the potential to prolong the QT interval or are arrhythmogenic [ see Warnings and Precautions (5.1]. 7.2 Insulin or Other Antidiabetic Drugs Hydroxychloroquine sulfate tablets may enhance the effects of insulin and antidiabetic drugs, and consequently increase the hypoglycemic risk. Therefore, a decrease in dosage of insulin and other antidiabetic drugs may be necessary [ see Warnings and Precautions (5.10) ]. 7.3 Drugs that Lower the Seizure Threshold Hydroxychloroquine sulfate tablets can lower the seizure threshold. Co-administration of hydroxychloroquine sulfate tablets with other antimalarials known to lower the seizure threshold (e.g., mefloquine) may increase the risk of seizures. 7.4 Antiepileptics The activity of antiepileptic drugs might be impaired if co-administered with hydroxychloroquine sulfate tablets. 7.5 Methotrexate Concomitant use of hydroxychloroquine sulfate tablets and methotrexate may increase the incidence of adverse reactions. 7.6 Cyclosporine An increased plasma cyclosporin level was reported when cyclosporin and hydroxychloroquine sulfate tablets were co-administered. Monitor serum cyclosporine levels closely in patients receiving combined therapy. 7.7 Digoxin Concomitant hydroxychloroquine sulfate tablets and digoxin therapy may result in increased serum digoxin levels. Monitor serum digoxin levels closely in patients receiving combined therapy. 7.8 Cimetidine Concomitant use of cimetidine resulted in a 2-fold increase of exposure of chloroquine, which is structurally related to hydroxychloroquine. Interaction of cimetidine with hydroxychloroquine cannot be ruled out. Avoid concomitant use of cimetidine. 7.9 Rifampicin Lack of efficacy of hydroxychloroquine was reported when rifampicin was concomitantly administered. Avoid concomitant use of rifampicin. 7.10 Praziquantel Chloroquine has been reported to reduce the bioavailability of praziquantel. Interaction of praziquantel with hydroxychloroquine cannot be ruled out. 7.11 Antacids and kaolin Antacids and kaolin can reduce absorption of chloroquine; an interval of at least 4 hours between intake of these agents and chloroquine should be observed. Interaction of antacids and kaolin with hydroxychloroquine cannot be ruled out. 7.12 Ampicillin In a study of healthy volunteers, chloroquine significantly reduced the bioavailability of ampicillin. Interaction of ampicillin with hydroxychloroquine cannot be ruled out.
Clinical pharmacology
Information about the clinical pharmacology and actions of the drug in humans.12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Malaria Hydroxychloroquine is a 4-aminoquinoline antimalarial [ see Microbiology (12.4) ] and antirheumatic agent. Rheumatoid Arthritis, Systemic Lupus Erythematosus and Chronic Discoid Lupus Erythematosus The mechanisms underlying the anti-inflammatory and immunomodulatory effects of hydroxychloroquine sulfate tablets in the treatment of rheumatoid arthritis, chronic discoid lupus erythematosus and systemic lupus erythematosus are not fully known. 12.2 Pharmacodynamics The exposure-response relationship and time course of pharmacodynamic response for the safety and effectiveness of hydroxychloroquine have not been fully characterized. 12.3 Pharmacokinetics Absorption Following a single 200 mg oral dose of hydroxychloroquine sulfate tablets to healthy male volunteers, whole blood hydroxychloroquine Cmax was 129.6 ng/mL (plasma Cmax was 50.3 ng/mL) with Tmax of 3.3 hours (plasma Tmax 3.7 hours). Following a single oral hydroxychloroquine sulfate tablets dose of 200 mg, the mean fraction of the dose absorbed was 0.74 (compared to administration of 155 mg of hydroxychloroquine intravenous infusion). Peak blood concentrations of metabolites were observed at the same time as peak levels of hydroxychloroquine. After administration of single 155 mg and 310 mg intravenous doses, peak blood concentrations ranged from 1161 ng/mL to 2436 ng/mL (mean 1918 ng/mL) following the 155 mg infusion and 6 months following the 310 mg infusion. Pharmacokinetic parameters were not significantly different over the therapeutic dose range of 155 mg and 310 mg indicating linear kinetics. In patients with rheumatoid arthritis, there was large variability as to the fraction of the dose absorbed (i.e. 30 to 100%), and mean hydroxychloroquine levels were significantly higher in patients with less disease activity. Distribution Hydroxychloroquine sulfate tablets is extensively distributed to tissues. Elimination A half-life of 123.5 days in plasma were observed following a single 200 mg oral hydroxychloroquine sulfate tablets dose to healthy male volunteers. Urine hydroxychloroquine levels were still detectable after 3 months with approximately 10% of the dose excreted as the parent drug. Results following a single dose of a 200 mg tablet versus i.v. infusion (155 mg), demonstrated a half-life of about 40 days and a large volume of distribution. Following chronic oral administration of hydroxychloroquine, the absorption half-life was approximately 3 to 4 hours and the terminal half-life ranged from 40 to 50 days. Metabolism Significant levels of three metabolites, desethylhydroxychloroquine (DHCQ), desethylchloroquine (DCQ), and bidesethylhydroxychloroquine (BDCQ) were found in plasma and blood, with DHCQ being the major metabolite. Excretion Renal clearance in patients with rheumatoid arthritis treated with hydroxychloroquine sulfate tablets for at least 6 months was similar to that in single dose studies in healthy volunteers, suggesting that no change in clearance occurred with chronic dosing. Renal clearance of unchanged drug was approximately 16% to 30%. 12.4 Microbiology Mechanism of Action in Malaria The precise mechanism by which hydroxychloroquine exhibits activity against Plasmodium is not known. Hydroxychloroquine is a weak base and may exert its effect by concentrating in the acid vesicles of the parasite and inhibiting polymerization of heme. It can also inhibit certain enzymes by its interaction with DNA. Antimicrobial Activity Hydroxychloroquine is active against the erythrocytic forms of chloroquine sensitive strains of P. falciparum, P. malariae, P. vivax, and P. ovale . Hydroxychloroquine is not active against the gametocytes and exoerythrocytic forms including the hypnozoite liver stage forms of P. vivax and P. ovale . Drug Resistance P. falciparum strains exhibiting reduced susceptibility to chloroquine also show reduced susceptibility to hydroxychloroquine. Resistance of Plasmodium parasites to chloroquine is widespread [see Indications and Usage (1.1)].

Geriatric use
Information about any limitations on any geriatric indications, needs for specific monitoring, hazards associated with use of the drug in the geriatric population.8.5 Geriatric Use Clinical trials of hydroxychloroquine sulfate tablets did not include sufficient numbers of patients 65 years of age and older to determine whether they respond differently from younger adult patients. Nevertheless, this drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. In general, dose selection in geriatric patients should start with the lowest recommended dose, taking into consideration the greater frequency of decreased hepatic, renal or cardiac function, and of concomitant disease or other drug therapy.
Labor and delivery
Information about the drug’s use during labor or delivery, whether or not the use is stated in the indications section of the labeling, including the effect of the drug on the mother and fetus, on the duration of labor or delivery, on the possibility of delivery-related interventions, and the effect of the drug on the later growth, development, and functional maturation of the child.8.2 Lactation Risk Summary Published lactation data report that hydroxychloroquine is present in human milk at low levels. No adverse reactions have been reported in breastfed infants. No retinal toxicity, ototoxicity, cardiotoxicity, or growth and developmental abnormalities have been observed in children who were exposed to hydroxychloroquine through breastmilk. There is no information on the effect of hydroxychloroquine on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for hydroxychloroquine sulfate tablets and any potential adverse effects on the breastfed child from hydroxychloroquine sulfate tablets or from the underlying maternal condition.
Pediatric use
Information about any limitations on any pediatric indications, needs for specific monitoring, hazards associated with use of the drug in any subsets of the pediatric population (such as neonates, infants, children, or adolescents), differences between pediatric and adult responses to the drug, and other information related to the safe and effective pediatric use of the drug.8.4 Pediatric Use The safety and effectiveness of hydroxychloroquine sulfate tablets have been established in pediatric patients for the treatment of uncomplicated malaria due to P. falciparum, P. malariae, P. vivax, and P. ovale , as well as for the prophylaxis of malaria in geographic areas where chloroquine resistance is not reported. However, this product cannot be directly administered to pediatric patients weighing less than 31 kg because the film-coated tablets cannot be crushed or divided [ see Dosage and Administration (2.1, 2.2)] . The safety and effectiveness of hydroxychloroquine sulfate tablets have not been established in pediatric patients for the treatment of rheumatoid arthritis, chronic discoid lupus erythematosus, or systemic lupus erythematosus.
Pregnancy
Information about effects the drug may have on pregnant women or on a fetus. This field may be ommitted if the drug is not absorbed systemically and the drug is not known to have a potential for indirect harm to the fetus. It may contain information about the established pregnancy category classification for the drug. (That information is nominally listed in the teratogenic_effects field, but may be listed here instead.)8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to hydroxychloroquine sulfate tablets during pregnancy. Encourage patients to register by contacting 1-877-311-8972. Risk Summary Prolonged clinical experience over decades of use and available data from published epidemiologic and clinical studies with hydroxychloroquine sulfate tablets use in pregnant women have not identified a drug-associated risk of major birth defects, miscarriage, or adverse maternal, or fetal outcomes (see Data). There are risks to the mother and fetus associated with untreated or increased disease activity from malaria, rheumatoid arthritis, and systemic lupus erythematosus in pregnancy (see Clinical Considerations) . Animal reproduction studies were not conducted with hydroxychloroquine. The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the US general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Disease-Associated Maternal and/or Embryo-Fetal Risk Malaria: Malaria during pregnancy increases the risk for adverse pregnancy outcomes, including maternal anemia, prematurity, spontaneous abortion, and stillbirth. Rheumatoid Arthritis: Published data suggest that increased disease activity is associated with the risk of developing adverse pregnancy outcomes in women with rheumatoid arthritis Adverse pregnancy outcomes include preterm delivery (before 37 weeks of gestation), low birth weight (less than 2500 g) infants, and small for gestational age at birth. Systemic Lupus Erythematosus: Pregnant women with systemic lupus erythematosus, especially those with increased disease activity, are at increased risk of adverse pregnancy outcomes, including spontaneous abortion, fetal death, preeclampsia, preterm birth, and intrauterine growth restriction. Passage of maternal auto-antibodies across the placenta may result in neonatal illness, including neonatal lupus and congenital heart block. Data Human Data Data from published epidemiologic and clinical studies have not established an association with hydroxychloroquine sulfate tablets use during pregnancy and major birth defects, miscarriage, or adverse maternal or fetal outcomes. Hydroxychloroquine readily crosses the placenta with cord blood levels corresponding to maternal plasma levels. No retinal toxicity, ototoxicity, cardiotoxicity, or growth and developmental abnormalities have been observed in children who were exposed to hydroxychloroquine in utero. Available epidemiologic and clinical studies have methodological limitations including small sample size and study design.
Use in specific populations
Information about use of the drug by patients in specific populations, including pregnant women and nursing mothers, pediatric patients, and geriatric patients.8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to hydroxychloroquine sulfate tablets during pregnancy.

Hydroxychloroquine readily crosses the placenta with cord blood levels corresponding to maternal plasma levels. No retinal toxicity, ototoxicity, cardiotoxicity, or growth and developmental abnormalities have been observed in children who were exposed to hydroxychloroquine in utero. Available epidemiologic and clinical studies have methodological limitations including small sample size and study design. 8.2 Lactation Risk Summary Published lactation data report that hydroxychloroquine is present in human milk at low levels. No adverse reactions have been reported in breastfed infants. No retinal toxicity, ototoxicity, cardiotoxicity, or growth and developmental abnormalities have been observed in children who were exposed to hydroxychloroquine through breastmilk. There is no information on the effect of hydroxychloroquine on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for hydroxychloroquine sulfate tablets and any potential adverse effects on the breastfed child from hydroxychloroquine sulfate tablets or from the underlying maternal condition. 8.4 Pediatric Use The safety and effectiveness of hydroxychloroquine sulfate tablets have been established in pediatric patients for the treatment of uncomplicated malaria due to P. falciparum, P. malariae, P. vivax, and P. ovale , as well as for the prophylaxis of malaria in geographic areas where chloroquine resistance is not reported. However, this product cannot be directly administered to pediatric patients weighing less than 31 kg because the film-coated tablets cannot be crushed or divided [ see Dosage and Administration (2.1, 2.2)] . The safety and effectiveness of hydroxychloroquine sulfate tablets have not been established in pediatric patients for the treatment of rheumatoid arthritis, chronic discoid lupus erythematosus, or systemic lupus erythematosus. 8.5 Geriatric Use Clinical trials of hydroxychloroquine sulfate tablets did not include sufficient numbers of patients 65 years of age and older to determine whether they respond differently from younger adult patients. Nevertheless, this drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. In general, dose selection in geriatric patients should start with the lowest recommended dose, taking into consideration the greater frequency of decreased hepatic, renal or cardiac function, and of concomitant disease or other drug therapy. 8.6 Patients with Renal or Hepatic Disease A reduction in the dosage of hydroxychloroquine sulfate tablets may be necessary in patients with hepatic or renal disease.
