Ferrous Fumarate
Uses of Ferrous Fumarate
Ferrous Fumarate is an iron supplement used to treat and prevent iron deficiency and iron deficiency anaemia.
Ferrous Fumarate is commonly used for:
• Iron deficiency anaemia: Replenishes low iron stores to support the production of haemoglobin and healthy red blood cells, relieving symptoms such as fatigue, weakness, breathlessness, pallor, and dizziness.
• Pregnancy: Meets the increased demand for iron during pregnancy to support fetal development and prevent maternal anaemia.
• Heavy menstrual bleeding (menorrhagia): Replaces iron lost through excessive monthly blood loss to prevent anaemia.
• Post-surgical or post-haemorrhage iron loss: Helps restore iron levels following significant blood loss during surgery or injury.
• Gastrointestinal conditions: Used in individuals with conditions such as coeliac disease or inflammatory bowel disease that reduce iron absorption from food.
• Dietary iron deficiency: Corrects iron deficiency in people whose diet does not provide adequate amounts of iron.

How Ferrous Fumarate works
Ferrous Fumarate works by providing elemental iron in the ferrous (Fe2+) form, which the body absorbs for haemoglobin production and red blood cell formation.
Iron is an essential mineral that the body uses in two key ways:
- Haemoglobin production: Iron is a critical component of haemoglobin, the protein inside red blood cells that binds to oxygen in the lungs and transports it to every tissue and organ in the body. Without adequate iron, the body cannot make enough haemoglobin, leading to iron deficiency anaemia.
- Myoglobin and cellular energy: Iron is also part of myoglobin (the oxygen-storing protein in muscles) and is needed by enzymes involved in energy production at the cellular level.
Ferrous Fumarate releases ferrous iron (Fe2+) in the stomach and small intestine, where it is absorbed through the intestinal lining into the bloodstream. Once in the blood, iron is transported by a protein called transferrin to the bone marrow, where it is incorporated into new red blood cells.
Over time, regular supplementation with Ferrous Fumarate raises iron stores (ferritin), increases haemoglobin levels, and improves the symptoms of iron deficiency anaemia.

Expert Advice
Dosage Forms Available
Ferrous Fumarate is available in tablets, film-coated tablets, extended-release tablets and capsules, chewable tablets, oral liquid suspensions or syrups, and drops for oral administration.
Age and Dose Restrictions
Ferrous Fumarate is meant for use in both adults and children. Specific formulations such as drops are tailored for infants and young children, making it accessible across various age groups.
Contraindications
This medicine is contraindicated in patients with hemochromatosis or hemosiderosis, conditions involving iron overload.
It is also contraindicated in individuals with active gastrointestinal bleeding or any known hypersensitivity to its components.
Other Medications to Avoid
Ferrous Fumarate may interact with antibiotics (eg., tetracyclines and fluoroquinolones), thyroid hormones (eg., levothyroxine), and medications used for Parkinson’s disease and hypertension (eg., levodopa and methyldopa), and medicines used for Wilson's disease and rheumatoid arthritis (eg., penicillamine).
Overdose and Missed Dose
- An overdose of Ferrous Fumarate can be serious, particularly in children. Symptoms of iron overdose may include severe nausea, vomiting, diarrhoea, stomach pain, and in serious cases, blood in vomit or stools, confusion, and signs of liver damage or cardiovascular collapse. If you suspect an iron overdose, seek emergency medical attention immediately. Iron toxicity is a medical emergency and requires urgent treatment.
If you miss a dose of Ferrous Fumarate, take it as soon as you remember. If it is nearly time for your next dose, skip the missed dose and continue with your regular schedule. Do not take two doses at the same time to compensate. Consistent daily use is important for effective treatment of iron deficiency anaemia, and treatment may need to continue for several months to replenish iron stores.
Management of Side Effects
Most side effects are temporary and generally harmless and resolve when discontinuing this medicine. However, if you experience any severe side effects or worsening of any of the symptoms, please consult your doctor.
To manage gastrointestinal side effects such as nausea or constipation, consider taking Ferrous Fumarate with food instead of on an empty stomach.
Staying hydrated can help mitigate constipation issues.
Use in Driving and Operating Machinery
Ferrous Fumarate does not directly affect your ability to drive or operate machinery. However, the symptoms of iron deficiency anaemia itself might cause fatigue or dizziness, impacting such activities.
Use in Pregnancy and Lactation
Ferrous Fumarate is commonly prescribed during pregnancy due to increased iron requirements. It is considered safe during breastfeeding as well. However, it is always advised to consult your doctor before starting any new medication during pregnancy or lactation.
Caution in Other Conditions
Caution should be exercised when using Ferrous Fumarate in individuals with existing gastrointestinal disorders such as inflammatory bowel disease or peptic ulcers due to the risk of irritation and bleeding.
Special Dietary and Lifestyle Recommendations
Consume a well-balanced diet rich in vitamin C to enhance iron absorption; fruits like oranges and strawberries are beneficial.
Avoid consuming tea, coffee, dairy products, or antacids within two hours of taking Ferrous Fumarate as they can impair iron absorption.
Engage in regular physical activity to improve overall health but monitor fatigue levels if you are anaemic.
Consider cooking with cast iron cookware which can subtly boost dietary iron intake.
