For
vitamin D deficiency, Uprise D3 60K (cholecalciferol 60,000 IU) once weekly for 6–8 weeks is a standard therapeutic dose, not a high dose. This is used to correct deficiency quickly, followed by a maintenance dose (usually 600–1000 IU/day). It is safe if given only once weekly (not daily) and for a limited duration. Ensure adequate dietary
calcium (milk, curd, paneer), otherwise vitamin D will not work effectively.
Regarding
ferritin 29.3 ng/mL, this is borderline/low iron stores (even if Hb is normal). Livogen-Z (iron + folic acid + zinc) is appropriate. However, in children, iron dose should ideally be calculated by weight (3 mg/kg/day of elemental iron). Many times tablet formulations may give slightly higher iron than needed, so it is better to: Prefer pediatric iron syrup for accurate dosing, OR
Continue tablet only if dose matches weight, after pediatrician confirmation
Important advice:
Iron should be given on empty stomach or with vitamin C (like lemon water) for better absorption
Avoid giving with milk
Watch for mild side effects like black stools, constipation (common and not harmful)
