Adverse Effects
Frequency Not Defined
Injection site reactions (eg, localized irritation, induration, infiltration, pain, erythema, wheal formation, eschar, burning, swelling, pruritus, crust, vesicles, local edema); these may be associated with systemic allergic reactions
Systemic reactions (eg, abdominal pain, arthralgia, asthma, fever, headache, myalgia, nausea, vomiting)
Cardiovascular reactions (eg, hypotension with too rapid IV infusion, tachycardia, shock)
Hypersensitivity reactions (eg, anaphylactic reaction with or without shock, angioedema, generalized rash, urticaria)
Digestive reactions (eg, abdominal discomfort, diarrhea, nausea, vomiting)
Hematologic reactions (eg, blood dyscrasia including thrombocytopenia and leucopenia)
Hepatic reactions (eg, increased transaminases, hepatic dysfunction)
Musculoskeletal reactions (eg, muscle spasms, growth retardation and bone changes including metaphyseal dysplasia are common in doses ≥ 60 mg/kg, especially those who begin iron chelation in the first three years of life; reduced risk if doses are kept to ≤ 40 mg/kg)
Nervous System reactions (eg, neurological disturbances including dizziness, peripheral sensory, motor, or mixed neuropathy, paresthesias, seizures; exacerbation or precipitation of aluminum-related dialysis encephalopathy)
Special Senses reactions (eg, high-frequency sensorineural hearing loss and/or tinnitus are uncommon if dosage guidelines are not exceeded and if dose is reduced when ferritin levels decline; visual disturbances inlcuding decreased acuity, blurred vision, loss of vision, dyschromatopsia, night blindness, visual field defects, scotoma, retinopathy (pigmentary degeneration), optic neuritis, and cataracts are rare if dosage guidelines are not exceeded)
Respiratory reactions (eg, acute respiratory distress syndrome with dyspnea, cyanosis, and/or interstitial infiltrates)
Very rare generalized rash
Urogenital reactions including dysuria, acute renal failure, increased serum creatinine and renal tubular disorders
Postmarketing Reports
Renal dysfunction, including renal failure; monitor patients for changes in renal function (eg, increased serum creatinine)
Warnings
Contraindications
Known hypersensitivity to deferoxamine or any of its components
Patients with severe renal disease or anuria
Cautions
Flushing of the skin, urticaria, hypotension, and shock have occurred when drug administered by rapid intravenous injection; best to administer IM slow SC or IV infusion
Rare cases of mucormycosis, some with a fatal outcome, reported with use; if any of suspected signs or symptoms occur, discontinue treatment; mycological tests should be carried out and appropriate treatment instituted immediately
Adult respiratory distress syndrome, also reported in children described following treatment with excessively high intravenous doses in patients with acute iron intoxication or thalassemia
Increases in serum creatinine (possibly dose-related), acute renal failure, and renal tubular disorders, reported in postmarketing experience; monitor patients for changes in renal function
Severe chronic iron overload may precipitate reversible cardiac function impairment if high doses of Vitamin C (>500 mg/day in adults) are given concomitantly; do not administer Vitamin C to HF patients; wait >1 month after treatment to begin supplemental vitamin C therapy; administer vitamin C only if the patient is receiving deferoxamine regularly, ideally soon after setting up the infusion pump; do not exceed a daily vitamin C dose of 200 mg in adults, given in divided doses; monitor cardiac function closely during such combined therapy
Dialysis patients with aluminum-related encephalopathy may experience neurological dysfunction (seizures), possibly due to an acute increase in circulating aluminum;onset of dialysis dementia may be precipitated; treatment in the presence of aluminum overload may result in decreased serum calcium and aggravation of hyperparathyroidism
Not a substitute for standard measures generally used in iron toxicity (eg, induced emesis, gastric lavage)
Iron overload increases susceptibility of patients to Yersinia enterocolitica and Yersinia pseudotuberculosis infections; treatment may therefpre enhance patient's susceptibility; if it occurs, treatment should be discontinued until infection is resolved
Monitor pediatric patients for body weight and growth every 3 months; high doses and concomitant low ferritin levels associated with growth retardation; after reduction of dose, growth velocity may partially resume to pretreatment rates
Ocular and auditory disturbances
- Ocular and auditory disturbances reported when therapy administered over prolonged periods of time, at high doses, or in patients with low ferritin levels; in most cases, both ocular and auditory disturbances were reversible upon immediate cessation of treatment
- Visual acuity tests, slit-lamp examinations, funduscopy and audiometry recommended periodically in patients treated for prolonged periods of time; toxicity is more likely to be reversed if symptoms or test abnormalities are detected early
-
Ocular disturbances observed include
- Blurring of vision; cataracts after prolonged administration in chronic iron overload
- Decreased visual acuity including visual loss, visual defects, scotoma
- Impaired peripheral, color, and night vision; optic neuritis, cataracts, corneal opacities, and retinal pigmentary abnormalities
-
Auditory abnormalities reported include
- Tinnitus and hearing loss including high-frequency sensorineural hearing loss

Pregnancy & Lactation
Pregnancy
There are no adequate and well-controlled studies in pregnant women; administer during pregnancy only if potential benefit justifies potential risk to fetus
Animal data
- Delayed ossification in mice and skeletal anomalies in rabbits observed after drug administered in daily doses up to 4.5 times the maximum daily human dose; no adverse effects observed in similar studies in rats
Lactation
Not known whether drug is excreted in human milk; because many drugs are excreted in human milk, caution should be exercised when administered to a nursing woman
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Desferal chelates iron by forming a stable complex that prevents the iron from entering into further chemical reactions; also chelates iron readily from ferritin and hemosiderin but not readily from transferrin; does not combine with the iron from cytochromes and hemoglobin; chelate is readily soluble and is renally excreted
Pharmacokinetics
Metabolism: Principally by plasma enzymes; pathways not yet defined
Excretion: Primarily urine; partly excreted in feces
Additional Information
100mg of deferoxamine binds to about 10mg of iron and 4.1mg of aluminum
End points of treatment are clinical improvement, resolution of anion gap and acidosis, return of urine color to baseline, serum iron level ≤ 100 mcg/dL
Vin Rose urine, or a change in urine color from baseline, indicates presence of deferoxamine-iron chelate; may not always be present, so cannot be used to rule out significant iron ingestion; patient should be advised to obtain baseline urine for visual comparison and keep at bedside
