- Iron Salt
Supplies a source to elemental iron necessary to the function of hemoglobin, myoglobin and specific enzyme systems; allows transport of oxygen via hemoglobin
Bound iron: 1 hour
Use: Labeled Indications
Iron deficiency anemia: Treatment of iron-deficiency anemia in patients undergoing hemodialysis in conjunction with erythropoietin therapy
Off Label Uses
Data from two prospective, randomized, open-label, multicenter trials supports the use of ferric gluconate in the management of patients with chemotherapy-associated anemia [Pedrazzoli 2008], [Henry 2007].
Known hypersensitivity to ferric gluconate or any component of the formulation
Iron-deficiency anemia, hemodialysis patients: IV: 125 mg elemental iron per dialysis session. Most patients will require a cumulative dose of 1 g elemental iron over approximately 8 sequential dialysis treatments to achieve a favorable response.
Note: A test dose of 2 mL diluted in NS 50 mL administered over 60 minutes was previously recommended (not in current manufacturer labeling). Doses >125 mg are associated with increased adverse events.
Chemotherapy-associated anemia (off-label use): IV infusion: 125 mg once every week for 6 doses (Pedrazzoli, 2008) or for 8 doses (Henry, 2007)
Refer to adult dosing.
Iron-deficiency anemia, hemodialysis patients: Children ≥6 years: IV: 1.5 mg/kg of elemental iron (maximum: 125 mg/dose) per dialysis session. Doses >1.5 mg/kg are associated with increased adverse events.
Dosing: Renal Impairment
No dosage adjustment necessary. The ferric gluconate iron complex is not dialyzable.
Dosing: Hepatic Impairment
No dosage adjustment necessary.
For IV infusion, dilute ferric gluconate in NS (children: 25 mL NS, adults: 100 mL NS).
Children: Administer diluted in 25 mL NS over 1 hour.
Adults: Administer diluted in 100 mL NS over 1 hour or administer undiluted, slowly at a rate of up to 12.5 mg/minute.
Store at 20°C to 25°C (68°F to 77°F); excursions permitted to 15°C to 30°C (59°F to 86°F). Do not freeze. Use immediately after dilution in NS.

<1% (Limited to important or life-threatening): Anaphylaxis, convulsions, facial flushing, hemorrhage, hypersensitivity reaction, hypertonia, hypoesthesia, loss of consciousness, shock, skin discoloration
Concerns related to adverse effects:
• Hypotension: Clinically significant hypotension may occur; usually resolves within 1-2 hours. May augment hemodialysis-induced hypotension.
• Hypersensitivity reactions: Serious hypersensitivity reactions, including anaphylactic-type reactions, have occurred (may be life-threatening). May present with shock, clinically significant hypotension, loss of consciousness, or collapse. Monitor during administration and for ≥30 minutes after administration and until clinically stable after infusion. Avoid rapid administration. Equipment for resuscitation and trained personnel experienced in handling medical emergencies should always be immediately available.
• Elderly: Use with caution in the elderly.
Dosage form specific issues:
• Benzyl alcohol and derivatives: Some dosage forms may contain benzyl alcohol; large amounts of benzyl alcohol (≥99 mg/kg/day) have been associated with a potentially fatal toxicity (“gasping syndrome”) in neonates; the “gasping syndrome” consists of metabolic acidosis, respiratory distress, gasping respirations, CNS dysfunction (including convulsions, intracranial hemorrhage), hypotension and cardiovascular collapse (AAP ["Inactive" 1997]; CDC, 1982); some data suggests that benzoate displaces bilirubin from protein binding sites (Ahlfors, 2001); avoid or use dosage forms containing benzyl alcohol with caution in neonates. See manufacturer’s labeling.
• Appropriate use: Use only in patients with documented iron deficiency; caution with hemoglobinopathies or other refractory anemias as iron overload may occur.
Hemoglobin and hematocrit, serum ferritin, iron saturation; vital signs; signs and symptoms of hypersensitivity (monitor for ≥30 minutes following the end of administration and until clinically stable)
NKF K/DOQI guidelines recommend that iron status should be monitored monthly during initiation through the percent transferrin saturation (TSAT) and serum ferritin.
Chemotherapy-associated anemia (off-label use): Iron, total iron-binding capacity, transferrin saturation, or ferritin levels at baseline and periodically (Rizzo, 2011).
Pregnancy Risk Factor
Adverse events were not observed in animal reproduction studies. It is recommended that pregnant women meet the dietary requirements of iron with diet and/or supplements in order to prevent adverse events associated with iron deficiency anemia in pregnancy. Treatment of iron deficiency anemia in pregnant women is the same as in nonpregnant women and in most cases, oral iron preparations may be used. Except in severe cases of maternal anemia, the fetus achieves normal iron stores regardless of maternal concentrations.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience diarrhea, cramps, abdominal pain, lack of appetite, or injection site irritation. Have patient report immediately to prescriber signs of high potassium (abnormal heartbeat, confusion, dizziness, passing out, weakness, shortness of breath, numbness or tingling feeling), angina, severe dizziness, passing out, burning or numbness feeling, cough, tachycardia, edema, chills, flushing, severe back pain, severe groin pain, severe thigh pain, sweating a lot, severe nausea, severe vomiting, severe headache, shortness of breath, or severe loss of strength and energy (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
