SODIUM FERRIC COMPLEX Drug Interactions: What You Need to Know

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.

Sodium ferric gluconate complex in sucrose injection is contraindicated in patients with known hypersensitivity to sodium ferric gluconate or any of its components. Reactions have included anaphylaxis [see Warnings and Precautions ( 5.1 ) ]. Known hypersensitivity to sodium ferric gluconate or any of its inactive components. ( 4 )

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>.
