Introduction
Ferrous fumarate and folic acid are often combined in dietary supplements to address deficiencies in iron and folate. Ferrous fumarate is an iron salt used to treat or prevent iron deficiency anemia, while folic acid is a form of vitamin B9 necessary for the formation of red blood cells and DNA synthesis.
Uses
The combination of ferrous fumarate and folic acid is used to:
- Treat and prevent iron deficiency anemia.
- Supplement folic acid in individuals with low levels, such as pregnant women or those with dietary deficiencies.
- Support overall hematologic health and improve red blood cell production.

Mechanism of Action
Ferrous fumarate provides elemental iron, which is essential for the production of hemoglobin and red blood cells. Folic acid is crucial for DNA synthesis and cell division. Together, they help correct iron and folate deficiencies, promoting the production of healthy red blood cells and preventing anemia.
How Long Does It Take to Work?
Improvement in symptoms of anemia, such as fatigue and weakness, can be observed within a few weeks of starting treatment. Full correction of anemia and normalization of blood parameters may take several months, depending on the severity of the deficiency and adherence to the regimen.
Absorption
Ferrous fumarate is absorbed in the gastrointestinal tract, primarily in the duodenum and jejunum. Folic acid is also absorbed in the upper part of the small intestine. Iron absorption can be enhanced by consuming the supplement with vitamin C or on an empty stomach, while folic acid absorption is generally efficient.
Route of Elimination
Ferrous fumarate is eliminated through feces and urine, with a majority of the absorbed iron being incorporated into hemoglobin or stored in the body. Folic acid is also excreted primarily through urine, with excess amounts being rapidly cleared from the body.
Dosage
Adults: One tablet daily. When necessary one tablet may be given twice daily. In pregnancy, it is recommended that Irolic tablet should be started at first antenatal consolation and continues for 3 months after delivery. The tablet should preferably be taken before meals; if there are gastro-intestinal disturbances, doses may be taken after meals.The dosage varies depending on the severity of deficiency and the formulation:
- For iron deficiency anemia: Typically, 100-200 mg of elemental iron per day (from ferrous fumarate) in divided doses.
- For folic acid deficiency: Usually 400-800 mcg per day, depending on individual needs and medical advice.
- For pregnant women: Often recommended as 27-30 mg of elemental iron and 400-800 mcg of folic acid daily, or as directed by a healthcare provider.
Administration
Ferrous fumarate and folic acid are usually administered orally in tablet or capsule form. It's important to follow the specific dosing instructions provided by a healthcare provider or included in the product labeling.
Side Effects
Common side effects of ferrous fumarate may include:
- Gastrointestinal discomfort, such as nausea, constipation, or diarrhea.
- Darkened stools.
- Allergic reactions.
- Unusual taste in the mouth.
Toxicity
Iron toxicity can occur with excessive intake, leading to symptoms such as abdominal pain, vomiting, and diarrhea. Severe cases can cause organ damage. Folic acid toxicity is rare but can potentially mask vitamin B12 deficiency symptoms if taken in excessive amounts.
Precautions
Precautions include:
- Monitor for symptoms of iron overload, especially in patients with hemochromatosis or other iron-storage disorders.
- Ensure adequate vitamin B12 levels to avoid masking deficiency symptoms with high doses of folic acid.
- Take the supplement as directed and avoid exceeding the recommended dosage.
Interaction
Ferrous fumarate may interact with:
- Certain antibiotics (e.g., tetracyclines), reducing their effectiveness.
- Antacids or calcium supplements, which can inhibit iron absorption.
- Anti-seizure medications, which may reduce folic acid levels.
- Some medications used for rheumatoid arthritis.
Disease Interaction
Use with caution in individuals with:
- Gastrointestinal diseases or conditions affecting iron absorption.
- Vitamin B12 deficiency, as folic acid supplementation can mask its symptoms.
Drug Interaction
Interactions may occur with:
- Iron supplements and certain medications affecting absorption, such as proton pump inhibitors or H2 blockers.
- Folic acid and medications that affect folate metabolism or absorption.
Food Interactions
Iron absorption can be inhibited by:
- Coffee and tea.
- Calcium-rich foods.
Pregnancy Use
Ferrous fumarate and folic acid are commonly used during pregnancy to prevent or treat anemia and support fetal development. Dosage should be adjusted based on individual needs and medical advice, often with higher doses recommended to meet increased nutritional requirements.
Lactation Use
These supplements are also considered safe during lactation. Adequate iron and folic acid levels are important for both maternal health and the nutritional quality of breast milk.
Acute Overdose
Acute overdose of iron can lead to severe symptoms, including gastrointestinal distress, systemic toxicity, and organ damage. Seek immediate medical attention if an overdose is suspected. Overdose of folic acid is less likely to cause serious harm but should still be monitored.
Contraindication
Ferrous fumarate and folic acid are contraindicated in:
- Individuals with known hypersensitivity to these compounds.
- Patients with iron overload conditions, such as hemochromatosis or hemosiderosis.
Use Direction
Follow the dosage instructions provided by the healthcare provider or included in the product labeling. Take the supplements with water, and avoid taking them with substances that may inhibit absorption, such as dairy products or antacids.
Storage Conditions
Store at room temperature, away from moisture and direct sunlight. Keep out of reach of children. Follow specific storage instructions provided with the product.
Volume of Distribution
The volume of distribution is not typically specified for ferrous fumarate and folic acid due to their oral administration and localized action in the body.
Half Life
The half-life of ferrous fumarate is not well-defined but is approximately 6-8 hours for iron in the body. Folic acid has a half-life of about 6 hours, but this can vary based on individual metabolism and dosage.
Clearance
Iron and folic acid are primarily cleared through the gastrointestinal tract and urine. Excess iron is stored in the body or eliminated through feces, while folic acid is excreted in urine.
