Warnings and precautions
Patients may present with shock, hypotension, loss of consciousness, and/or collapse. Signs and symptoms of hypersensitivity should be observed during and after administration for at least 30 minutes. More risk is for patients with known allergies including drug allergies, patients with a history of severe asthma, eczema or another atopic allergy.
The most common adverse reactions are nausea followed by headache, hypertension, flushing, hypophosphatemia, and dizziness. FCM is well tolerated than oral ferrous sulfate, having a low risk of hypersensitivity reactions and gastrointestinal adverse effects. (15)
FCM in Post-partum anemia (12)
This can be defined as haemoglobin (Hb) of < 10 gm% during the postpartum period due to loss of blood during delivery. FCM is efficiently used in this condition. FCM is front line therapy because it can be administered 1000mg doses in one setting as well as has a fewer adverse reaction and better compliance.
