Ferrous Sulfate: Brands, Price & Uses in Bangladesh

Established / FDA-Approved Uses

• Treatment of iron-deficiency anemia: Ferrous Sulfate is indicated for the treatment of anemia caused by iron deficiency, confirmed by low serum ferritin, low hemoglobin, and other laboratory findings consistent with iron deficiency.
• Prevention of iron-deficiency anemia: Ferrous Sulfate is used to prevent iron deficiency in individuals at increased risk, including pregnant women, infants born prematurely or with low birth weight, children in periods of rapid growth, and people on iron-poor diets.

Guideline-Supported Uses

• Iron supplementation during pregnancy and lactation: Ferrous Sulfate is recommended by obstetric guidelines to meet the increased iron requirements of pregnancy and to prevent maternal and fetal complications of iron-deficiency anemia.
• Chronic blood loss states: used as adjunct therapy to replace iron lost from chronic gastrointestinal bleeding, heavy menstrual bleeding, or regular blood donation, once the underlying cause has been identified and addressed.

Adjunct / Combination Uses

• Ferrous Sulfate may be combined with other hematinics (e.g., folic acid, vitamin B12, vitamin C) as adjunct therapy in specific anemia protocols where multiple deficiencies coexist; in such cases it is used alongside, not as a replacement for, treatment of the other deficiencies.

Ferrous Sulfate does not treat anemia that is not due to iron deficiency (e.g., anemia of chronic disease, hemolytic anemia, or vitamin B12/folate deficiency anemia) and should not be used for these without confirmed iron deficiency.

Adult Dose - Iron-Deficiency Anemia (Treatment)

Some clinicians and recent evidence favor alternate-day dosing of Ferrous Sulfate (rather than multiple daily doses) toimprove fractional iron absorption and reduce gastrointestinal side effects; the prescribing physician'sinstructions should be followed.

Pediatric Dose

Renal/Hepatic Impairment

No well-established dose adjustment of Ferrous Sulfate is required for renal or hepatic impairment, as oral iron is notsignificantly cleared by the kidney or metabolized by the liver; however, patients with hepatic disease shoulduse Ferrous Sulfate under medical supervision because of a theoretical risk of iron accumulation.

Administration Notes

• For best absorption, take Ferrous Sulfate on an empty stomach, about 1 hour before or 2 hours after meals.
• If gastrointestinal upset occurs, Ferrous Sulfate may be taken with food, but this reduces the amount of iron absorbed.
• Do not take Ferrous Sulfate at the same time as antacids, calcium supplements, dairy products, tea, or coffee - separatethese by at least 2 hours (see Interactions).
• Swallow tablets/capsules whole with water; do not crush enteric-coated or extended-release forms.

Common (Expected/Usually Not Serious)

• Nausea, epigastric/abdominal discomfort
• Constipation or, less commonly, diarrhea
• Dark or black-colored stools (a harmless, expected effect of unabsorbed iron - not a sign of bleeding, though patients with unexplained melena should still seek medical evaluation)
• Metallic taste; temporary staining of teeth with liquid formulations (rinse mouth or use a straw)

Less Common

• Vomiting, heartburn
• Allergic skin reactions (rash, itching) in sensitive individuals

Serious (Rare, Usually Related to Overdose)

Iron overdose from Ferrous Sulfate can cause serious, potentially fatal toxicity, especially in young children - seeOverdose section. Any signs of severe abdominal pain, vomiting blood, black tarry stools with instability, orlethargy after excessive intake require immediate emergency care.
