6 ADVERSE REACTIONS The following clinically significant adverse reactions are discussed in greater detail in other sections of the labeling: Hypersensitivity Reactions [see Warnings and Precautions ( 5.1 )] Hypophosphatemia [see Warnings and Precautions ( 5.2 )] Hypertension [see Warnings and Precautions ( 5.3 )] Laboratory Test Alterations [see Warnings and Precautions ( 5.4 )] The most common adverse reactions in adult patients (>2%) are nausea, hypertension, flushing, injection site reactions, erythema, hypophosphatemia, and dizziness.
( 6.1 ) The most common adverse reactions in pediatric patients (≥4%) are hypophosphatemia, injection site reactions, rash, headache, and vomiting.

6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, the adverse reaction rates observed cannot be directly compared to rates in other clinical trials and may not reflect the rates observed in clinical practice.
Adults In two randomized clinical studies [Studies 1 and 2, see Clinical Studies ( 14 ) ], a total of 1,775 patients were exposed to Injectafer 15 mg/kg body weight up to a maximum single dose of 750 mg of iron on two occasions separated by at least 7 days up to a cumulative dose of 1,500 mg of iron.
Adverse reactions reported by ≥1% of treated patients are shown in the following table.

Flushing includes flushing and hot flush.
Injection site reactions include injection site extravasation, injection site discoloration, injection site pain, injection site irritation, injection site bruising, injection site reaction, injection site discomfort, injection site erythema, injection site hematoma, injection site hemorrhage, injection site pruritus, injection site rash, and injection site swelling.
Erythema includes erythema and injection site erythema.
5 WARNINGS AND PRECAUTIONS Hypersensitivity Reactions: Observe for signs and symptoms of hypersensitivity during and after Injectafer administration for at least 30 minutes and until clinically stable following completion of each administration.
( 5.1 ) Symptomatic Hypophosphatemia: Monitor serum phosphate levels in patients at risk for low serum phosphate who require a repeat course of treatment.
( 5.2 ) Hypertension: Monitor patients closely for signs and symptoms of hypertension following each Injectafer administration.
( 5.3 ) 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 Injectafer.
Patients may present with shock, clinically significant hypotension, loss of consciousness, and/or collapse.
Like all medications, Injectafer can cause side effects. However, not everyone who takes this medication will experience them. Many side effects are dose-dependent and may improve as your body adjusts to the medication. Others may require dose adjustment or medical attention.
