2.1 Important Administration Instructions The dosage of sodium ferric gluconate complex in sucrose injection is expressed in terms of mg of elemental iron.

Each

5 mL sterile, single dose vial contains 62.5 mg of elemental iron (12.5 mg/mL). Do not mix sodium ferric gluconate complex in sucrose injection with other medications or add to parenteral nutrition solutions for intravenous infusion. The compatibility of sodium ferric gluconate complex in sucrose injection with intravenous infusion vehicles other than 0.9% sodium chloride has not been evaluated. Parenteral drug products should be inspected visually for particulate matter and discoloration before administration, whenever the solution and container permit. If diluted, use immediately. Sodium ferric gluconate complex in sucrose injection treatment may be repeated if iron deficiency reoccurs.

2.2 Adult Dosage and Administration The recommended dosage of sodium ferric gluconate complex in sucrose injection for the repletion treatment of iron deficiency in hemodialysis patients is 10 mL of sodium ferric gluconate complex in sucrose injection (125 mg of elemental iron). Sodium ferric gluconate complex in sucrose injection may be diluted in 100 mL of 0.9% sodium chloride administered by intravenous infusion over 1 hour per dialysis session. Sodium ferric gluconate complex in sucrose injection may also be administered undiluted as a slow intravenous injection (at a rate of up to 12.5 mg/min) per dialysis session. For repletion treatment most patients may require a cumulative dose of 1000 mg of elemental iron administered over 8 dialysis sessions. Sodium ferric gluconate complex in sucrose injection has been administered at sequential dialysis sessions by infusion or by slow intravenous injection during the dialysis session itself. Data from sodium ferric gluconate complex in sucrose injection postmarketing spontaneous reports indicate that individual doses exceeding 125 mg may be associated with a higher incidence and/or severity of adverse events <span class="opacity-50 text-xs">[see Adverse Reactions ( 6.2 ) ]</span>.

2.3 Pediatric Dosage and Administration The recommended pediatric dosage of sodium ferric gluconate complex in sucrose injection for the repletion treatment of iron deficiency in hemodialysis patients is 0.12 mL/kg sodium ferric gluconate complex in sucrose injection (1.5 mg/kg of elemental iron) diluted in 25 mL 0.9% sodium chloride and administered by intravenous infusion over 1 hour per dialysis session. The maximum dosage should not exceed 125 mg per dose.

6.2 Postmarketing Experience In the single-dose, postmarketing, safety study, 11% of patients who received sodium ferric gluconate complex in sucrose injection and 9.4% of patients who received placebo reported adverse reactions. The most frequent adverse reactions following sodium ferric gluconate complex in sucrose injection administration were: hypotension (2%), nausea, vomiting and/or diarrhea (2%), pain (0.7%), hypertension (0.6%), allergic reaction (0.5%), chest pain (0.5%), pruritus (0.5%), and back pain (0.4%). The following additional events were reported in two or more patients: hypertonia, nervousness, dry mouth, and hemorrhage. In the multiple-dose, open-label surveillance study, 28% of the patients received concomitant angiotensin-converting enzyme inhibitor (ACEI) therapy. The incidences of both drug intolerance and suspected allergic events following first dose sodium ferric gluconate complex in sucrose injection administration were 1.6% in patients with concomitant ACEI use compared to 0.7% in patients without concomitant ACEI use. The patient with a life-threatening event was not on ACEI therapy. One patient had facial flushing immediately on sodium ferric gluconate complex in sucrose injection exposure. No hypotension occurred and the event resolved rapidly and spontaneously without intervention other than drug withdrawal. 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. The following additional adverse reactions have been identified with the use of sodium ferric gluconate complex in sucrose injection from postmarketing spontaneous reports: Cardiovascular System: shock, fetal bradycardia, injection site superficial thrombophlebitis, phlebitis, acute myocardial ischemia with or without myocardial infarction or with in-stent thrombosis in the context of a hypersensitivity reaction.

Immune

System: anaphylactic-type reactions.

Nervous

System: loss of consciousness, generalized convulsion, hypoesthesia. Skin and Appendages: skin discoloration, pallor. Individual doses exceeding 125 mg may be associated with a higher incidence and/or severity of adverse events based on information from postmarketing spontaneous reports. These adverse events included hypotension, nausea, vomiting, abdominal pain, diarrhea, dizziness, dyspnea, urticaria, chest pain, paresthesia, and peripheral swelling.

AND PRECAUTIONS Hypersensitivity Reactions: Monitor patients for signs and symptoms of hypersensitivity during and after sodium ferric gluconate complex in sucrose injection administration for at least 30 minutes and until clinically stable following completion of the infusion. Only administer sodium ferric gluconate complex in sucrose injection when personnel and therapies are immediately available for the treatment of anaphylaxis and other hypersensitivity reactions. ( 5.1 ) Hypotension: Sodium ferric gluconate complex in sucrose injection may cause hypotension. Monitor patients for signs and symptoms of hypotension during and following each sodium ferric gluconate complex in sucrose injection dose. ( 5.2 )

Iron

Overload: Regularly monitor hematologic responses during sodium ferric gluconate complex in sucrose injection therapy. Do not administer sodium ferric gluconate complex in sucrose injection to patients with iron overload. ( 5.3 )

Benzyl Alcohol

Toxicity: Premature and low-birth-weight infants may be more likely to develop toxicity. ( 5.4 )

5.1 Hypersensitivity Reactions Serious hypersensitivity reactions, including anaphylactic-type reactions, some of which have been life-threatening and fatal, have been reported in patients receiving sodium ferric gluconate complex in sucrose injection in postmarketing experience. Patients may present with shock, clinically significant hypotension, loss of consciousness, or collapse. Monitor patients for signs and symptoms of hypersensitivity during and after sodium ferric gluconate complex in sucrose injection administration for at least 30 minutes and until clinically stable following completion of the infusion. Only administer sodium ferric gluconate complex in sucrose injection when personnel and therapies are immediately available for the treatment of anaphylaxis and other hypersensitivity reactions <span class="opacity-50 text-xs">[see Adverse Reactions ( 6 ) ]</span>. In the single-dose, postmarketing safety study one patient experienced a life-threatening hypersensitivity reaction (diaphoresis, nausea, vomiting, severe lower back pain, dyspnea, and wheezing for 20 minutes) following sodium ferric gluconate complex in sucrose injection administration.

Among

1,097 patients who received sodium ferric gluconate complex in sucrose injection in this study, there were 9 patients (0.8%) who had an adverse reaction that, in the view of the investigator, precluded further sodium ferric gluconate complex in sucrose injection administration. These included one life-threatening reaction, six allergic reactions (including pruritus, facial flushing, chills, dyspnea/chest pain, and rash), and two other reactions (hypotension and nausea).

Another

2 patients experienced (0.2%) allergic reactions not deemed to represent drug intolerance (nausea/malaise and nausea/dizziness) following sodium ferric gluconate complex in sucrose injection administration.

5.2 Hypotension Sodium ferric gluconate complex in sucrose injection may cause clinically significant hypotension. Hypotension associated with lightheadedness, malaise, fatigue, weakness or severe pain in the chest, back, flanks, or groin has been reported. These hypotensive reactions may or may not be associated with signs and symptoms of hypersensitivity reactions and usually resolve within one to two hours. In the single-dose safety study, postadministration hypotensive events were observed in 22/1,097 patients (2%) following sodium ferric gluconate complex in sucrose injection administration. Transient hypotension may occur during dialysis. Administration of sodium ferric gluconate complex in sucrose injection may augment hypotension caused by dialysis. Monitor patients for signs and symptoms of hypotension during and following sodium ferric gluconate complex in sucrose injection administration <span class="opacity-50 text-xs">[see Adverse Reactions ( 6.1 ) ]</span>.

5.3 Iron Overload Excessive therapy with parenteral iron can lead to excess storage of iron with the possibility of iatrogenic hemosiderosis. Patients receiving sodium ferric gluconate complex in sucrose injection require periodic monitoring of hematologic and iron parameters (hemoglobin, hematocrit, serum ferritin, and transferrin saturation).

5.4 Risk of Serious Adverse Reactions in Infants Due to Benzyl Alcohol Preservative Sodium ferric gluconate complex in sucrose injection is not approved for use in neonates or infants. Serious and fatal adverse reactions including &quot;gasping syndrome&quot; can occur in neonates and low-birth-weight infants treated with benzyl alcohol-preserved drugs, including sodium ferric gluconate complex in sucrose injection. The &quot;gasping syndrome&quot; is characterized by central nervous system depression, metabolic acidosis, and gasping respirations. The minimum amount of benzyl alcohol at which serious adverse reactions may occur is not known (Sodium ferric gluconate complex in sucrose injection contains 9 mg of benzyl alcohol per mL) <span class="opacity-50 text-xs">[see Use in Specific Populations ( 8.4 ) ]</span>.

INTERACTIONS Drug-drug interactions involving sodium ferric gluconate complex in sucrose injection have not been studied. Sodium ferric gluconate complex in sucrose injection may reduce the absorption of concomitantly administered oral iron preparations.
