Ferrous%252525252520ascorbate

# Ferrous Ascorbate ## Overview Ferrous ascorbate is a compound consisting of iron (Fe²⁺) and ascorbic acid (Vitamin C). The presence of ascorbic acid facilitates the reduction of ferric iron to the more absorbable ferrous state and maintains iron solubility in the duodenum, significantly enhancing bioavailability compared to other oral iron salts. ## Primary Indications * Iron deficiency anemia (IDA). * Prophylaxis of iron deficiency during pregnancy and lactation. * Increased iron requirements due to chronic blood loss or malabsorption. ## Adult Dosing * **Treatment of IDA:** 100 mg (elemental iron) once or twice daily. * **Maintenance/Prophylaxis:** 50–100 mg (elemental iron) daily. * **Maximum Dose:** Typically 200 mg elemental iron daily; gastrointestinal tolerance often limits higher doses. * *Note: Dosing depends on institutional protocol and severity of anemia; efficacy should be assessed via hemoglobin response.* ## Pediatric Dosing * **Treatment of IDA:** 3–6 mg/kg/day (elemental iron) divided into 1–2 doses. * **Maximum Dose:** Do not exceed 200 mg elemental iron/day unless directed by a hematologist. * *Note: Always verify content; products vary in the ratio of iron to ascorbic acid.* ## Dose Adjustments * **Renal Impairment:** No specific adjustment required, but use with caution in patients with history of iron overload (e.g., hemodialysis patients receiving IV iron). * **Hepatic Impairment:** Generally safe; monitor for signs of iron overload in patients with chronic liver disease. ## Contraindications * Hypersensitivity to iron or ascorbic acid. * Hemosiderosis or hemochromatosis. * Hemolytic anemia (unless iron deficiency is proven). * Repeated blood transfusions. ## Adverse Effects * **Common:** Dark or black-colored stools (harmless), gastrointestinal irritation, nausea, abdominal pain, diarrhea, or constipation. * **Serious:** Severe allergic reactions (rare); acute iron toxicity (especially in children). ## Key Drug Interactions * **Antacids/H2 Blockers/PPIs:** Reduce acid-dependent absorption; separate by 2–4 hours. * **Fluoroquinolones/Tetracyclines:** Iron forms insoluble chelates; administer iron 2 hours before or 4–6 hours after these antibiotics. * **Levothyroxine:** Iron reduces absorption; separate by at least 4 hours. ## Monitoring * **Hemoglobin/Hematocrit:** Re-assess 2–4 weeks after initiation to track response. * **Ferritin/Iron Studies:** Monitor iron stores 3 months after normalizing hemoglobin to determine duration of therapy. * **Toxicity:** Observe for signs of overdose in pediatric populations (vomiting, diarrhea, hematemesis, shock). ## Clinical Pearls * **Absorption:** Best absorbed on an empty stomach; however, if GI side effects are limiting, taking with a small amount of food is acceptable, noting this may decrease bioavailability. * **Ascorbic Acid Benefit:** The added ascorbic acid often mitigates the need for high doses by increasing absorption efficiency, potentially reducing GI distress compared to ferrous sulfate. * **Safety:** Always store out of reach of children. Iron poisoning in pediatric patients is frequently fatal at relatively low doses. *** *Disclaimer: This information is for educational purposes and does not substitute for clinical judgment.
