Used For:

• Treatment and prevention of Vitamin D3 deficiencyOsteoporosis (bone thinning) – as adjunct to calcium therapyOsteomalacia / Rickets (soft bones due to deficiency)Hypocalcemia (low calcium levels due to low vitamin D)Pregnancy and lactation support (to ensure maternal and fetal bone health)In elderly – improves bone strength and prevents fracturesIn chronic kidney/liver disorders (under supervision)

Contraindications:

• Hypercalcemia (high calcium levels)Vitamin D toxicityHyperparathyroidismSarcoidosis or other granulomatous diseases (can cause excess vitamin D activity)Severe renal impairment (risk of calcium deposition)Hypersensitivity to cholecalciferol or excipients

Side Effects:

• Usually well-tolerated in prescribed doses.Nausea, vomitingConstipation or abdominal discomfortMetallic taste, dry mouthOverdose or toxicity (with long-term high doses):Hypercalcemia (weakness, confusion, bone pain, kidney stones)Increased thirst and urinationCardiac rhythm disturbances (severe cases)

Precautions:

• Take only under medical supervision — excess vitamin D can cause toxicity.Monitor blood calcium and vitamin D levels in long-term therapy.Elderly, pregnant, or kidney-impaired patients require dose adjustments.Avoid self-medicating with multiple vitamin D products simultaneously.Use with calcium supplements only if prescribed.

Dietary Restrictions:

• Take after meals containing fat or milk for best absorption.Avoid excessive calcium intake (milk, cheese, calcium tablets) unless advised.Limit alcohol and caffeine, which may reduce calcium absorption.Include natural vitamin D sources in diet:Egg yolk, fortified milk, fish (salmon, sardines, tuna)Safe sun exposure (15–20 minutes/day) helps natural vitamin D synthesis.Stay hydrated to prevent kidney strain if taking calcium together.
