Hematogen Forte Description

Each brown soft gelatin capsule contains:

Ferrous fumarate..... 460 mg

(151 mg elemental iron)

Ascorbic acid..... 60 mg

Folic acid..... 1 mg

Cyanocobalamin.....10 mcg

The amount of elemental iron and the absorption of the iron components of commercial iron preparations vary widely. It is further established that certain "accessory components" may be included to enhance absorption and utilization of iron. Hematogen Forte Capsules are formulated to provide the essential factors for a complete, versatile hematinic.

Inactive Ingredients: Soybean oil, Lecithin, Glycerin, hydrogenated soybean oil, Yellow Beewax, Titanium Oxide.


High Elemental Iron Content: Ferrous fumarate, used in Hematogen Forte Capsules, is an organic iron complex which has the highest elemental iron content of any hematinic salt - 33%. This compares with 20% for 1,2 ferrous sulfate (heptahydrate) and 13% for ferrous gluconate. Hematogen Forte contains 151 mg of elemental iron.

More Complete Absorption: It has been repeatedly shown that ascorbic acid, when given in sufficient amounts, can increase the absorption of ferrous iron from the gastrointestinal tract. The absorption promoting effect is mainly due to the reducing action of ascorbic acid within the gastrointestinal lumen, 3 which help to prevent or delay the formation of insoluble or less dissociated ferric compounds.

Promotes Movement Of Plasma Iron: Ascorbic acid also plays an important role in the movement of plasma iron to storage depots in the tissues. The action, which leads to the transport of plasma iron to ferritin, presumably involves its reducing effect, converting transferrin iron from the ferric to the ferrous state. There is also evidence that ascorbic acid improves iron utilization, presumably as a further result of its reducing action, and some evidence that it may have a direct effect upon erythropoiesis. Ascorbic acid is further alleged to enhance the conversion of folic acid to a more physiologically active form, folinic acid, which would make it even more important in the treatment of anemia since it would aid in the utilization of dietary folic acid.

Excellent Oral Toleration: Ferrous fumarate is used in Hematogen Forte Capsules because it is less likely to cause the gastric disturbances so often associated with oral iron therapy. Ferrous fumarate has a low ionization constant and high solubility in the entire pH range of the gastrointestinal tract. It does not precipitate proteins or have the astringency of more ionizable forms of iron, and does not interfere with proteolytic or diastatic activities of the digestive system. Because of excellent oral toleration, Hematogen Forte Capsules can usually be administered between meals when iron absorption is maximal.

Folic Acid Supplementation: The use of supplemental folic acid may be indicated in patients with increased requirements for this vitamin, such as iron deficiency anemia. Folic acid administration may reduce the risk of neural tube defects in the developing fetus. Folic acid has also been shown to reduce circulating homocysteine levels in the blood. Folate as methyltetrahydrofolate and B as methylcobalamin are involved in the remethylation reaction of homocysteine to methionine. Elevated homocysteine plasma levels are associated with increased risk of preeclampsia, neural tube defects, myocardial infarction and atherosclerosis.

Toxicity: Ferrous fumarate was found to be the least toxic of three popular oral iron salts, with an oral LD 50 of 630 mg/kg. In the same report, the LD of ferrous gluconate was reported to be 320 mg/kg and ferrous sulfate 230 mg/kg.

Indications and Usage for Hematogen Forte

For the treatment of all anemias responsive to oral iron therapy, such as hypochromic anemia associated with pregnancy, chronic or acute blood loss, dietary restriction, metabolic disease and post-surgical convalescence.


Hemochromatosis and hemosiderosis are contraindications to iron therapy. Folic acid is contraindicated in patients with pernicious anemia (see PRECAUTIONS). Soybean oil, Lecithin, Di Calcium phosphate anhydrous, Beeswax yellow, hydrogenated soybean oil.

Adverse Reactions/Side Effects

Average capsule doses in sensitive individuals or excessive dosage may cause nausea, skin rash, vomiting, diarrhea, precordial pain, or flushing of the face and extremities.


Folic acid should not be prescribed until the diagnosis of pernicious anemia has been eliminated, since it can alleviate the hematologic manifestations, while allowing neurological damage to 23 continue undetected

Pediatric Use

Safety and effectiveness in pediatric patients has not been established.

Geriatric Use

Clinical studies on this product have not been performed in sufficient numbers of subjects aged 65 and over to determine whether elderly subjects respond differently from younger subjects. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosage range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of noncomitant

Hematogen Forte Dosage and Administration

Usual adult dose is 1-2 soft gelatin capsules daily, or as directed by a physician.
