Ferronal 35

Uses

Iron-deficiency anemia.

Ferronal 35 is also used to associated treatment for these conditions: Folate deficiency, Iron Deficiency (ID), Iron Deficiency Anemia (IDA), Zinc Deficiency, Mineral supplementation

How Ferronal 35 works

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

Dosage

Ferronal 35 dosage

Iron-deficiency anaemia:

• Adult:60 mg bid up to 60 mg 4 times daily. Prevention: 60 mg daily.
• Child:Severe: 4-6 mg/kg/day in 3 divided doses; Mild to moderate: 3 mg/kg/day in 1-2 divided doses. Prevention: 1-2 mg/ kg/ day.

Should be taken on an empty stomach. Best taken on an empty stomach. May be taken with meals to reduce GI discomfort.

Side Effects

GI symptoms e.g. stomach cramping, constipation, nausea, vomiting, dark stools, heartburn, diarrhea, teeth staining, urine discoloration.

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

Avoid in patients with peptic ulcer, enteritis, or ulcerative colitis and those who receive frequent blood transfusions. Not to be used in premature infants until the vitamin E stores (deficient at birth) are replenished. Avoid prolonged treatment (>6 mth) except in patients with continuous menorrhagia or bleeding.

Interaction

Concurrent admin with antacids/ H2 antagonists may reduce absorption of iron. Chloramphenicol may delay response to iron. Iron may reduce the absorption of levodopa, methyldopa and penicillamine when given together. Absorption may be reduced when used with quinolones or tetracyclines. Concurrent admin with vitamin C may increase iron absorption.

Food Interaction

• Avoid milk and dairy products. Take ferrous gluconate at least 2 hours before or after milk.
• Limit caffeine intake. Food and beverages containing caffeine may reduce iron absorption.
• Take at least 2 hours before or after calcium supplements.
• Take separate from antacids. Take ferrous gluconate at least 2 hours before or after antacids.
• Take with food. This reduces gastric irritation.
• Take with foods containing vitamin C. Foods rich in vitamin C increase the absorption of iron.

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.

Pregnancy & Breastfeeding use

Pregnancy Category- A. Adequate and well-controlled human studies have failed to demonstrate a risk to the fetus in the first trimester of pregnancy (and there is no evidence of risk in later trimesters).

Contraindication

Haemochromatosis, haemolytic anemia.

Acute Overdose

Overdose may lead to severe iron toxicity, espcially in children.
