Indications: Egshel‑D is used for the treatment of:

Bone loss (osteoporosis)
Weak bones (osteomalacia, osteopenia)
Rickets
Decreased activity of the parathyroid gland (hypoparathyroidism)
Latent tetany (certain muscle disorders)

It may also be used to ensure adequate calcium and vitamin D₃ in conditions such as:

Pregnancy and lactation
Post‑menopausal osteoporosis
Senile osteoporosis
Drug‑induced osteoporosis (e.g., phenytoin, phenobarbital, prednisolone)

Composition:

500 mg & 200 IU: Each film‑coated tablet contains Calcium Carbonate BP (eggshell source) 1250 mg equivalent to 500 mg elemental calcium + Vitamin D₃ (Cholecalciferol) BP 200 IU.
600 mg & 400 IU: Each film‑coated tablet contains Calcium Carbonate BP (eggshell source) 1500 mg equivalent to 600 mg elemental calcium + Vitamin D₃ BP 400 IU.

Description: This is a natural combination of Calcium Carbonate (eggshell source) and Vitamin D₃. Eggshell calcium is highly digestible (98%), more absorbable, and eco‑friendly compared to algae, coral, or rock‑based calcium. It enriches bone matrix, increases bone density, and contains soluble transport proteins for maximum absorption. It also provides trace minerals like magnesium, phosphorus, and strontium for bone development.

Pharmacology: Calcium is essential for bones, nerves, muscles, and vital organs. Deficiency leads to bone resorption and weakness. Vitamin D₃ enhances calcium absorption. Adequate calcium and vitamin D₃ are crucial for strong bones and healthy muscles.

Dosage & Administration:

Route: Oral.
Adults: One tablet in the morning and one at night, or as directed by physician.
Children/adolescents: As directed by physician.

Interactions:

Medicines: Possible interactions with digoxin, antacids (calcium/aluminum/magnesium), other calcium supplements, calcitriol, tetracyclines, doxycycline, aminocycline, oxytetracycline. Physician consultation required.
Food: Spinach, milk, and dairy products may reduce intestinal calcium uptake.

Contraindications:

Hypercalcemia / hyperparathyroidism
Hypercalciuria / nephrolithiasis
Hypersensitivity to components
Severe renal insufficiency
Concomitant digoxin therapy (requires monitoring of serum calcium)

Side Effects:

Common: GI irritation, constipation (rare with eggshell calcium).
Rare: Kidney stones, hypercalcemia, alkalosis, loss of appetite.
