Study Notes
Ferrous Salts and Iron Deficiency Anemia
- Ferrous salts are the most commonly prescribed supplements for iron deficiency anemia, with a dose of 20-30mg/kg/day in divided doses.
- Ferrous sulfate is the most tried and tested preparation, providing 30% of elemental iron.
Types of Oral Iron Supplements
- There are two main types of oral iron supplements: ferrous and ferric salts.
- Ferrous salts have a relative bioavailability of 20%, 12%, and 33%.
- Ferrous sulphate is the most cost-effective but has more gastrointestinal side effects and is poorly tolerated.
- Ferrous gluconate contains 12% elemental iron, has less gastrointestinal effects, and is dosed once to three times daily.
- Ferrous fumarate contains 33% elemental iron, is well tolerated, but is expensive and requires a prescription.
Dosage and Administration of Oral Iron Supplements
- The standard recommended dose is 200 mg three times a day, providing 180 mg of elemental iron per day.
- Lower doses of iron are as effective as higher doses if they can be absorbed.
- Reducing the frequency of dosing is important for improving compliance.
Side Effects and Precautions of Oral Iron Supplementation
- Oral iron supplementation is generally contraindicated in certain conditions, such as chronic hemolytic anemias and anemia of chronic disease.
- Iron supplementation can cause systemic allergic reactions, such as rashes, hives, arthralgia, and myalgia.
- Gastrointestinal side effects, such as constipation, diarrhea, nausea, vomiting, epigastric discomfort, and black tarry stools, are common with oral iron salts.
- Patients experiencing gastrointestinal side effects may benefit from adjunctive therapy with vitamin C and/or a short course of an antiemetic.
