TL-Fol 500 caplets are a hematinic for oral administration containing iron in a controlled-release dose form; Vitamin C for enhancement of iron absorption; and Folic Acid. TL-Fol 500 caplets are oval, maroon, film-coated caplets debossed "TL51".

When oral iron is administered between meals it is absorbed most efficiently, Traditional iron preparations frequently cause gastric irritation when taken on an empty stomach. Studies with iron in controlled release form have indicated that relatively little of the iron is released in the stomach, gastric intolerance occurs infrequently, and hematologic response is consistent with that obtained from immediate release ferrous sulfate.

Iron is found in the body principally as hemoglobin. It is stored in the liver, spleen, and bone marrow in the form of ferritin. Concentrations of plasma iron and the total iron-binding capacity of plasma vary greatly in different physiological conditions and disease states.

Vitamin C (Ascorbic Acid) plays a role in anemia therapy. It augments the conversion of folic acid to its active form, folinic acid. In addition, Vitamin C promotes the reduction of ferric iron in food to the more readily absorbed ferrous form. Severe and prolonged Vitamin C deficiency is associated with an anemia that is usually hypochromic but occasionally megaloblastic in type.

Iron and Folic Acid are absorbed in the proximal small intestine, particularly the duodenum. While folic acid is absorbed maximally and rapidly at this site, iron is absorbed in a descending gradient from the duodenum distally.

Folic Acid, after absorption, is rapidly converted into its metabolically active forms. Half of the folic acid stored in the body is found in the liver. It is also concentrated in the spinal fluid. Approximately two-thirds is bound to plasma protein. The percentage of absorption of food folates averages about 10% except for the folates ingested in egg yolk, liver and yeast.

Contraindicated in patients with pernicious anemia and in the rare instance of hypersensitivity to folic acid. Hemochromatosis and hemosiderosis are contraindications to iron therapy.

Anemia is a manifestation that requires appropriate investigation to determine its cause or causes. Folic acid alone is unwarranted in the treatment of vitamin B₁₂ deficiency states such as pernicious anemia. Folic acid, especially in doses above 100 mcg daily may obscure pernicious anemia in that hematological remission may occur while neurological manifestations remain progressive. Concomitant parenteral therapy with vitamin B₁₂ may be necessary for adequate treatment of patients with a deficiency of vitamin B₁₂. Pernicious anemia is rare in women of childbearing age, and the likelihood of its occurrence along with pregnancy is reduced by the impairment of fertility associated with vitamin B₁₂ deficiency. In older patients and those with conditions tending to lead to vitamin B₁₂ depletion, serum B₁₂ levels should be regularly assessed during treatment.

Rarely, controlled-release iron produces gastrointestinal reactions, such as diarrhea or constipation. Administering the dose with meals will minimize these effects in the iron-sensitive patient. Allergic sensitization has been reported with both oral and parenteral administration of folic acid.

Signs and symptoms of iron toxicity, which may be delayed because the iron is in a controlled-release form, may include pallor and cyanosis, vomiting of blood, diarrhea, passage of dark-colored stool, shock, drowsiness and coma. In overdosage, efforts should be made to hasten the elimination of the caplets ingested. An emetic should be administered as soon as possible, followed by gastric lavage if indicated. Immediately following emesis, a large dose of saline cathartic should be used to speed passage through the intestinal tract. X-ray examination may then be considered to determine the position and number of caplets remaining in the gastrointestinal tract.

TL-Fol 500 is supplied in bottles of 30 caplets.
