Ferrous Fumarate 140mg/5ml: Uses, Dosage, and BNF Guidelines

Ferrous fumarate 140mg/5ml is a commonly prescribed iron supplement used to treat and prevent iron deficiency anemia. This liquid formulation is particularly useful for individuals who have difficulty swallowing tablets, such as children or elderly patients. The British National Formulary (BNF) provides clear guidelines on its dosage, administration, and precautions.

Uses of Ferrous Fumarate 140mg/5ml
Iron deficiency anemia occurs when the body lacks sufficient iron to produce hemoglobin. Ferrous fumarate replenishes iron levels, helping to restore energy, improve cognitive function, and support overall health. It is often recommended for:
– Pregnant women (to prevent anemia)
– Patients with chronic blood loss (e.g., heavy menstrual bleeding)
– Individuals with poor dietary iron intake

Dosage and Administration (BNF Guidelines)
The BNF recommends the following dosages for ferrous fumarate 140mg/5ml:
– Adults & Elderly: 5ml (140mg iron) 1-2 times daily
– Children (6 months+): 2.5ml (70mg iron) 1-2 times daily (adjusted by weight)

Take it on an empty stomach for better absorption, but if gastrointestinal side effects occur, it can be taken with food. Avoid taking it with tea, coffee, or antacids, as they reduce iron absorption.

Side Effects and Precautions
Common side effects include:
– Constipation
– Nausea
– Stomach cramps
– Darkened stools (harmless)

Severe iron overdose can be dangerous, especially in children. Always store it safely and follow the prescribed dose.

Conclusion
Ferrous fumarate 140mg/5ml is an effective iron supplement when used as per BNF guidelines. Consult a healthcare provider for personalized dosing and monitoring to ensure optimal results.
