Venofer® (iron sucrose injection, USP) is a brown, sterile, aqueous, complex of polynuclear iron (III)- hydroxide in sucrose for intravenous use. Iron sucrose injection has a molecular weight of approximately 34,000 – 60,000 daltons and a proposed structural formula:

[Na₂Fe₅O₈(OH)·3(H₂O)]_n · m(C₁₂H₂₂O₁₁)

where: n is the degree of iron polymerization and m is the number of sucrose molecules associated with the iron (III)-hydroxide.

Each mL contains 20 mg elemental iron as iron sucrose in water for injection. Venofer® is available in 5 mL single dose vials (100 mg elemental iron per 5 mL) and 10 mL single dose vials (200 mg elemental iron per 10 mL). The drug product contains approximately 30% sucrose w/v (300 mg/mL) and has a pH of 10.5- 11.1. The product contains no preservatives. The osmolarity of the injection is 1,250 mOsmol/L.

Therapeutic class: Hematinic
