Treatment and prevention of iron deficiency anemia; folate deficiency; commonly prescribed during pregnancy and for patients with increased iron requirements such as those with malabsorption, heavy menstrual bleeding, or chronic blood loss.
Ferrous iron provides the essential building block for hemoglobin, the oxygen-carrying protein in red blood cells. Folic acid (vitamin B9) supports red blood cell maturation and DNA synthesis, helping to replenish circulating blood cells more effectively.
Take on an empty stomach when possible for optimal absorption (unless GI intolerance occurs). Avoid concurrent calcium, antacids, or tetracyclines which can reduce iron absorption. May cause constipation, nausea, or dark stools. Store away from children. Do not exceed recommended dose; excess iron can be harmful.
