Ferinject®. C: Ferric carboxymaltose. I: Iron deficiency when treatment with oral iron is insufficiently effective, ineffective, or impossible. Po: The total cumulative dose of Ferinject must be calculated individually. Ferinject may be administered as an IV infusion (diluted in 0.9% NaCl) or as an IV injection (undiluted) at weekly doses of up to 1000 mg. Contraindications: Hypersensitivity to the active ingredient or to any of the excipients; known severe hypersensitivity to any other parenterally administered iron; anemia without confirmed iron deficiency; iron overload; first trimester of pregnancy. Precautions: Screen patients prior to each administration of Ferinject for adverse events related to previous administration of intravenous iron preparations. Qualified medical personnel must be immediately available and capable of assessing and treating anaphylactic reactions. Administer only in a facility equipped with all necessary resuscitation equipment. Monitor patients for at least 30 minutes after administration for signs and symptoms of a hypersensitivity reaction. Paravenous administration may cause brown discoloration and should therefore be avoided. Use with caution in cases of acute or chronic infections, asthma, or atopic allergies. Take into account the sodium content, which may reach up to 5.5 mg/mL. Parenteral iron may cause hypophosphatemia, which is generally transient and asymptomatic. Isolated cases of hypophosphatemia requiring treatment have been reported in patients who primarily had known risk factors and received a higher dose over an extended period. In cases of high-dose/long-term treatment and risk factors, monitor for hypophosphatemic osteomalacia. Consult a physician in case of arthralgia or bone pain. G/A: Contraindicated during the 1st trimester. Use during the 2nd and 3rd trimesters only under strict medical supervision. Fetal bradycardia may occur following a hypersensitivity reaction in the mother; the fetus must be monitored during administration. Adverse Effects: Common: hypophosphatemia, headache, facial flushing, dizziness, hypertension, nausea, injection/infusion site reactions. Uncommon: immediate-type hypersensitivity reactions, paresthesias, tachycardia, hypotension, rash, dyspnea, gastrointestinal disturbances, dysgeusia, rash, pruritus, urticaria, erythema, myalgia, arthralgia, muscle cramps, fever, fatigue, peripheral edema, chills, pain, elevated levels of AST, ALT, gamma-GT, LDH, and ALP.
