I now have enough information from authoritative sources. Here is the complete, well-sourced answer:
Iron Syrup Dosing - 12.5 kg Female Child
Standard Iron Syrup Formulation
Most commercially available pediatric iron syrups (e.g., Ferrous Sulfate, Ferrous Ascorbate, or Ferric Ammonium Citrate syrups) contain 25 mg elemental iron per 5 mL (1 teaspoon).
Dose Calculation for 12.5 kg
| Purpose | Dose | Calculation (12.5 kg) | Volume (25 mg/5 mL syrup) |
|---|---|---|---|
| Treatment (iron deficiency anemia) | 3-6 mg/kg/day elemental iron | 37.5 - 75 mg/day | 7.5 - 15 mL/day |
| Standard treatment dose | 3 mg/kg/day (in 2 divided doses) | ~37.5 mg/day | ~7.5 mL/day (given as ~3.75 mL twice daily) |
| Prophylaxis / supplementation | 1-2 mg/kg/day | 12.5 - 25 mg/day | 2.5 - 5 mL/day |
Practical prescription for treatment:
Syrup Iron (25 mg elemental iron / 5 mL) - 5 mL (1 tsp) TWICE daily, given between meals
This gives ~50 mg elemental iron/day (~4 mg/kg/day), a well-tolerated therapeutic dose.
Key Dosing Rules
- Treatment of iron deficiency anemia: 3-6 mg/kg/day of elemental iron, given in 2-3 divided doses, between meals - [Rosen's Emergency Medicine](standard ref); per [Park's Preventive Medicine](ref: elemental iron 3 mg/kg/day in two divided doses, preferably between meals)
- Prophylaxis (breastfed infants/preterm): 2 mg/kg/day - Harriet Lane Handbook, 23rd ed.
- Children weighing 15-30 kg can take half the average adult dose - Goodman & Gilman's Pharmacological Basis of Therapeutics
- Avoid giving iron with food - absorption is reduced by meals, antacids, and tea
- Vitamin C (ascorbic acid) co-administration improves absorption
Duration of Therapy
- Continue for 3 months after Hb normalizes to replenish iron stores
- Hemoglobin typically rises at ~1-2 g/dL per month with adequate treatment
- Recheck CBC at 4 weeks to confirm response
Common Iron Syrups in India (reference)

Important: Always verify the elemental iron content per mL on the label before prescribing, as formulations vary significantly between brands.
