After IV Iron, and with ongoing oral supplementation, a patient’s hemoglobin will start to rise 3-7 days. You can expect a 1-2 point rise in the hemoglobin per day, and after 2-4 weeks the hemoglobin will have risen 20-30g/L. Ferrous sulfate 300mg contains 60mg of elemental iron and 1 tab can be taken each night on an empty stomach at least 2 hours after meals with Vitamin C 500mg. Patients should also avoid taking with calcium or magnesium supplements as these decrease absorption.
