Ferofolic

# ferofolic ## Overview - **Classification**: Oral Iron Supplement (Ferrous Fumarate/Sulfate/Gluconate) and Folic Acid combination. - **Mechanism**: Iron is essential for hemoglobin synthesis and oxygen transport. Folic acid is vital for DNA synthesis, red blood cell maturation, and normal cell division. ## Primary Indications 1. **Iron Deficiency Anemia (IDA)** - Treatment of anemia due to combined iron and folate deficiency. 2. **Megaloblastic Anemia** - Treatment of megaloblastic anemia where iron deficiency is also present. 3. **Nutritional Supplementation** - Prophylaxis of iron and folate deficiencies, especially during pregnancy or in high-risk individuals. ## Adult Dosing ### Standard Dosing **Iron Deficiency Anemia / Nutritional Supplementation** - **Dose**: **60-100 mg elemental iron** and **400-800 mcg folic acid** - **Frequency**: Once daily - **Route**: Oral - **Duration**: Typically 3-6 months after hemoglobin normalizes for iron stores. ### Dose Adjustments - **Renal Impairment**: No specific dose adjustment needed. Use with caution in patients on dialysis due to potential for iron overload if frequent transfusions or IV iron are also given. - **Hepatic Impairment**: No specific dose adjustment needed. Caution in severe liver disease due to increased risk of iron accumulation if hemochromatosis is present. - **Elderly Patients**: Use standard adult doses. Monitor for GI side effects. ## Pediatric Dosing *Note: Dosing for "ferofolic" combinations in pediatrics should be based on elemental iron and folic acid components.* ### Neonates (0-28 days) - **Iron Dose**: Not typically indicated for iron deficiency in neonates unless specific diagnosis (e.g., severe hemorrhage) and under specialist guidance. - **Folic Acid Dose (for deficiency)**: **100-500 mcg** once daily. - **Frequency**: Once daily - **Maximum**: Refer to specific product guidelines for elemental iron maximums. - **Special Notes**: Liquid formulations are preferred for ease of administration and accurate dosing. Iron can stain teeth; administer with a dropper or straw. ### Infants (1-12 months) - **Iron (Prophylaxis for high-risk, e.g., premature)**: **1-2 mg/kg/day** elemental iron. - **Iron (Treatment of IDA)**: **3 mg/kg/day** elemental iron (divided 1-2 times daily). - **Folic Acid (Prophylaxis/Treatment)**: **100-500 mcg** once daily. - **Frequency**: Once or twice daily depending on total dose. - **Maximum**: Up to **15 mg elemental iron/kg/day** (max **75 mg elemental iron/day**). Do not exceed **300 mcg/kg/day** folic acid. ### Children (1-12 years) - **Iron (Prophylaxis)**: **1-2 mg/kg/day** elemental iron. - **Iron (Treatment of IDA)**: **3-6 mg/kg/day** elemental iron (divided 1-3 times daily). - **Folic Acid (Prophylaxis/Treatment)**: **400-800 mcg** once daily. - **Frequency**: Once or twice daily. - **Maximum**: **200 mg elemental iron/day**. Maximum **1 mg/day** folic acid. ### Adolescents (13-18 years) - **Dose**: Approach adult dosing, typically **60-100 mg elemental iron** and **400-800 mcg folic acid**. - **Frequency**: Once daily. - **Maximum**: Adult maximum dose **200 mg elemental iron/day**. ## Safety Information ### Contraindications - **Absolute**: Hemochromatosis, hemosiderosis (iron overload conditions). - **Absolute**: Non-iron deficiency anemias (e.g., hemolytic anemia, aplastic anemia). - **Absolute**: Known hypersensitivity to iron salts or folic acid. - **Relative**: Active peptic ulcer disease, regional enteritis, ulcerative colitis (may exacerbate GI irritation). ### Common Adverse Effects - **Very Common (>10%)**: Darkening of stools, constipation, nausea, abdominal pain. - **Common (1-10%)**: Diarrhea, vomiting, heartburn, metallic taste. - **Serious but Rare**: Iron toxicity (in overdose, especially in children), allergic reactions (rash, pruritus). ### Key Drug Interactions - **Fluoroquinolones (ciprofloxacin, levofloxacin)**: Iron significantly reduces absorption. Separate by **at least 2 hours before or 6 hours after** iron. - **Tetracyclines (doxycycline, minocycline)**: Iron reduces absorption. Separate by **2 hours before or 4 hours after** iron. - **Levothyroxine**: Iron can impair absorption. Separate by **at least 4 hours**. - **Antacids, PPIs, H2-blockers**: Reduce iron absorption (increase gastric pH). Avoid concomitant use or separate doses. - **Methotrexate**: Folic acid can antagonize methotrexate's effects. Avoid concurrent high doses of folic acid in patients on methotrexate for cancer. ## Monitoring & Follow-up - **Before Treatment**: Hemoglobin (Hb), Hematocrit (Hct), Mean Corpuscular Volume (MCV), Serum Ferritin, Transferrin Saturation, Reticulocyte count, Red Blood Cell Folate. - **During Treatment**: Hb/Hct every 2-4 weeks until stable, then monthly. Ferritin after 2-3 months to assess iron stores. - **Clinical Signs**: Resolution of fatigue, pallor, pica. Monitor for GI side effects. ## Clinical Pearls - 💡 **Enhanced Absorption**: Take iron on an empty stomach (1 hour before or 2 hours after meals) for best absorption, if tolerated. - 💡 **Vitamin C**: Co-administration with Vitamin C (e.g., orange juice) can enhance iron absorption. - 💡 **Stool Color**: Inform patients that stools will turn dark or black; this is harmless. - 💡 **Pediatric Safety**: Iron is a leading cause of fatal poisoning in young children. Store out of reach and in child-resistant containers. - 💡 **Persistence**: Treatment for iron deficiency often requires several months to replenish iron stores after Hb normalizes. > **⚠️ Important**: This information is for educational purposes only.
