Used For:

• Osteoporosis (postmenopausal, senile, steroid-induced)Osteomalacia or ricketsFracture healingHypocalcemia (low blood calcium)Pregnancy and lactation (increased calcium demand)Growing children and adolescentsCalcium deficiency due to dietary insufficiencyAdjunct therapy in chronic conditions like kidney disease or long-term corticosteroid use

Contraindications:

• Avoid or use cautiously in:Hypercalcemia (high blood calcium levels)Hypercalciuria (high urinary calcium excretion)Nephrolithiasis (kidney stones) or history of renal calculiSevere renal impairment or renal failureSarcoidosis (may cause vitamin D overproduction)Hypersensitivity to calcium or vitamin D3 supplements

Side Effects:

• Mild side effects may include:ConstipationNausea, vomiting, or abdominal discomfortFlatulence or bloatingMetallic taste (rare)Overdose or chronic misuse can lead to:Hypercalcemia (symptoms: fatigue, confusion, nausea, increased urination, bone pain)Kidney stones or calcificationMuscle weakness

Precautions:

• Take after meals to enhance absorption and reduce stomach irritation.Drink plenty of water to prevent kidney stones.Avoid overdose or combining with other calcium/vitamin D supplements.Monitor calcium and renal function during long-term use.In pregnancy and lactation, use under medical advice (safe in recommended doses).Elderly patients and those with renal disease require close supervision.

Dietary Restrictions:

• Maintain a calcium-rich diet: milk, yogurt, cheese, green leafy vegetables, almonds, sesame, fish (with bones).Get adequate sunlight exposure (natural source of vitamin D).Avoid excessive caffeine, alcohol, and smoking — they reduce calcium absorption.Limit high-oxalate foods (spinach, beet greens) and phosphate-rich processed foods, which hinder calcium uptake.Avoid taking iron, zinc, or tetracycline antibiotics at the same time — separate by at least 2 hours.Avoid taking with antacids containing aluminum or magnesium (may interfere with absorption).
