Instafer Uses, Dosage, Side Effects, Food Interaction and all others data.

Ferrous ascorbate, a synthetic molecule of ascorbic acid and iron.

Ferrous Ascorbate when administered is converted to ferric form and immediately is reduced to the ferrous form into the stomach. This reduced ferrous form is then transferred to the duodenum where it is highly absorbed. Ferrous Ascorbate has the advantage of providing both ferrous ion and ascorbate in the same compound. There is no dissociation on entering GI Tract due to the stable chelate of iron with ascorbate. Folic Acid itself is biochemically inactive, is converted to tetrahydrofolic acid and methyltetrahydrofolate by dihydrofolate reductase in liver. These folic acid congeners are transported across cells by receptor-mediated endocytosis where they are needed to maintain numerous body functions.

The major activity of supplemental iron is in the prevention and treatment of iron deficiency anemia. Iron has putative immune-enhancing, anticarcinogenic and cognition-enhancing activities.

Uses

Indicated in the treatment of iron deficiency anemia.

How Instafer works

Iron is necessary for the production of hemoglobin. Iron-deficiency can lead to decreased production of hemoglobin and a microcytic, hypochromic anemia.

Dosage

Instafer dosage

Adult & Elderly: One tablet (33 mg) a day before or after meal (food independent absorption) or as directed by the physician. In more severe cases, two tablets a day may be required as prescribed by the physician. Safety and effectiveness in pediatric patients have not been established.

Side Effects

The treatment of a neurotic patient was interrupted because of nausea and regurgitation. In pregnant women, the incidence of pyrosis and chronic constipation is slightly increased.

Toxicity

Acute iron overdosage can be divided into four stages. In the first stage, which occurs up to six hours after ingestion, the principal symptoms are vomiting and diarrhea. Other symptoms include hypotension, tachycardia and CNS depression ranging from lethargy to coma. The second phase may occur at 6-24 hours after ingestion and is characterized by a temporary remission. In the third phase, gastrointestinal symptoms recur accompanied by shock, metabolic acidosis, coma, hepatic necrosis and jaundice, hypoglycemia, renal failure and pulmonary edema. The fourth phase may occur several weeks after ingestion and is characterized by gastrointestinal obstruction and liver damage. In a young child, 75 milligrams per kilogram is considered extremely dangerous. A dose of 30 milligrams per kilogram can lead to symptoms of toxicity. Estimates of a lethal dosage range from 180 milligrams per kilogram and upwards. A peak serum iron concentration of five micrograms or more per ml is associated with moderate to severe poisoning in many.

Precaution

Oral iron preparations may aggravate existing peptic ulcer, regional enteritis and ulcerative colitis. Iron compounds taken orally can impair the absorption of tetracycline antibiotics. Antacids given concomitantly with iron compounds decrease iron absorption.

Elimination Route

The efficiency of absorption depends on the salt form, the amount administered, the dosing regimen and the size of iron stores. Subjects with normal iron stores absorb 10% to 35% of an iron dose. Those who are iron deficient may absorb up to 95% of an iron dose.
