Ferrous Gluconate


Iron-deficiency anemia.


Ferrous gluconate is used in the prevention and treatment of iron-deficiency anaemia. It replaces iron found in haemoglobin, myoglobin and enzymes. It also allows transportation of oxygen via haemoglobin.

Dosage & Administration

Iron-deficiency anaemia:
  • Adult: 60 mg bid up to 60 mg 4 times daily. Prevention: 60 mg daily.
  • Child: Severe: 4-6 mg/kg/day in 3 divided doses; Mild to moderate: 3 mg/kg/day in 1-2 divided doses. Prevention: 1-2 mg/ kg/ day.
Should be taken on an empty stomach. Best taken on an empty stomach. May be taken with meals to reduce GI discomfort.


Concurrent admin with antacids/ H2 antagonists may reduce absorption of iron. Chloramphenicol may delay response to iron. Iron may reduce the absorption of levodopa, methyldopa and penicillamine when given together. Absorption may be reduced when used with quinolones or tetracyclines. Concurrent admin with vitamin C may increase iron absorption.
