Ferrous Fumarate: Brands, Price & Uses in Bangladesh

Ferrous Fumarate is an oral iron salt used to replenish body iron stores. Its evidence-based indications are as follows:

Established/Approved Uses

• Treatment of iron-deficiency anemia confirmed or strongly suspected by laboratory findings (e.g., low serum ferritin, low hemoglobin/hematocrit with microcytic, hypochromic red cells).
• Prevention (prophylaxis) of iron-deficiency anemia in individuals at increased risk of iron deficiency, such as pregnant women, and people with chronic blood loss or inadequate dietary iron intake.

Guideline-Supported / Adjunct Uses

• As part of routine antenatal supplementation (often combined with folic acid) to reduce the risk of maternal anemia, in line with WHO antenatal care recommendations.
• As an adjunct in the management of anemia associated with chronic conditions where iron deficiency has been demonstrated (e.g., chronic kidney disease, chronic blood loss from gastrointestinal conditions), used alongside treatment of the underlying cause.

Ferrous Fumarate is not indicated for anemias that are not due to iron deficiency (e.g., anemia of chronic disease without iron deficiency, hemolytic anemia, or megaloblastic anemia due to vitamin B12/folate deficiency alone), since iron will not correct these and may cause harmful iron accumulation.

Adult Dosing

Pediatric Dosing

For children, dosing of Ferrous Fumarate is calculated on a weight (mg/kg) basis of elemental iron; see Pediatric Uses for details. Use only under medical supervision and with an appropriate pediatric formulation (e.g., drops or syrup) for accurate dosing.

Renal/Hepatic Impairment

No specific dose adjustment of oral Ferrous Fumarate is well established for renal or hepatic impairment; however, in chronic kidney disease with anemia, treatment is typically guided by a physician alongside monitoring of iron studies, given differing iron requirements in this population.

Administration

Ferrous Fumarate is best absorbed when taken on an empty stomach (e.g., one hour before or two hours after meals), ideally with water or a source of vitamin C (such as orange juice) to enhance absorption. If gastrointestinal upset occurs, it may be taken with food, though this may reduce absorption. Tablets should be swallowed whole (unless chewable) and not crushed unless the product is designed for that. Liquid formulations should be measured with an appropriate dosing device and may be diluted or taken through a straw to avoid staining teeth. Doses of other medications known to interact with iron should be separated by at least 2-4 hours (see Drug Interactions).

The most common side effects of Ferrous Fumarate are gastrointestinal and are generally dose-related:

• Nausea, epigastric discomfort or pain
• Constipation (most common) or, less often, diarrhea
• Dark or black-colored stools — this is an expected, harmless effect of unabsorbed iron and should not be confused with melena (tarry, foul-smelling stools indicating gastrointestinal bleeding); consult a physician if there is uncertainty or accompanying symptoms such as abdominal pain or blood in stool.
• Temporary staining of teeth with liquid formulations if not properly administered

Less common effects include heartburn and, rarely, hypersensitivity reactions. If severe abdominal pain, vomiting, or signs of an allergic reaction occur, discontinue and seek medical advice.
