Indications and Usage for Ferrex 28
For the nutritional supplementation of anemias responsive to oral iron, such as hypochromic anemia associated with pregnancy, chronic or acute blood loss, dietary restriction, metabolic disease and post-surgical convalescence.
Contraindications
This product is contraindicated in patients with a known hypersensitivity to any of the ingredients. Hemochromatosis and hemosiderosis are contraindications to iron supplementation.
Warnings
Folic acid alone is improper therapy in the treatment of pernicious anemia and other megaloblastic anemias where vitamin B12 is deficient.
Precautions
General
Do not exceed recommended dose.
The type of anemia and the underlying cause or causes should be determined before taking Ferrex™ 28 Tablets. Since the anemia may be a result of a systemic disturbance, such as recurrent blood loss, the underlying cause or causes should be corrected, if possible.
Folic Acid
Folic acid in doses above 0.1 mg daily may obscure pernicious anemia in that hematologic remission can occur while neurological manifestations remain progressive. Pernicious anemia should be excluded before using this product since folic acid may mask the symptoms of pernicious anemia.
Geriatric Use
Clinical studies on this product have not been performed in 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 dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug supplementation.
Adverse Reactions/Side Effects
Adverse reactions with iron supplementation may include constipation, diarrhea, nausea, vomiting, dark stools and abdominal pain. Adverse reactions with iron supplementation are usually transient.
Allergic sensitization has been reported following both oral and parenteral administration of folic acid.
Overdosage
The clinical course of acute iron overdosage can be variable. Initial symptoms may include abdominal pain, nausea, vomiting, diarrhea, tarry stools, melena, hematemesis, hypotension, tachycardia, metabolic acidosis, hyperglycemia, dehydration, drowsiness, pallor, cyanosis, lassitude, seizures, shock and coma.
