Medadin

Colecalciferol, the active ingredient in Medadin, is a Vitamin D presented as an oral supplement for oral use. It treats vitamin D deficiency and helps maintain healthy bone mineralization in both adults and children through enhanced calcium and phosphate absorption.

GNH USA supplies Medadin as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to stringent quality standards and provides reliable logistics for global distribution. Clients benefit from comprehensive regulatory support and consistent product availability across diverse markets.

Medadin (colecalciferol) is used to correct vitamin D deficiency and related bone disorders. - Vitamin D deficiency: restores normal serum 25‑hydroxyvitamin D concentrations. - Osteomalacia: promotes bone mineralization to alleviate softening of bones in adults. - Rickets: supports proper bone growth and prevents deformities in children. - General bone health: assists in maintaining calcium balance for healthy skeletal maintenance.

Oral colecalciferol is generally well tolerated, but some individuals may experience adverse reactions.

Common Side Effects: - Nausea - Constipation - Mild hypercalcemia (elevated blood calcium) - Headache - Fatigue

Serious or Rare Side Effects: - Severe hypercalcemia with symptoms such as vomiting, polyuria, and cardiac arrhythmias - Hypercalciuria leading to kidney stone formation - Allergic reactions including rash, pruritus, or angioedema - Hypersensitivity anaphylaxis (extremely rare)

When using Medadin, certain precautions should be observed to ensure safety and effectiveness. - Assess baseline serum calcium and 25‑hydroxyvitamin D levels before initiating therapy. - Monitor calcium levels periodically in patients at risk of hypercalcemia. - Use with caution in individuals with renal impairment or granulomatous diseases. - Avoid excessive concurrent intake of other vitamin D or calcium supplements without medical guidance. - Store at ambient temperature below 25 °C: keep in the original container, protect from moisture and direct sunlight.

Colecalciferol may interact with other medicines, altering its efficacy or safety profile.

Major Interactions (Avoid): - Thiazide diuretics: can increase risk of hypercalcemia. - Vitamin D analogues (e.g., calcitriol): may cause additive hypercalcemic effects. - High-dose calcium supplements: may lead to excessive calcium accumulation.

Moderate Interactions (Monitor Closely): - Anticonvulsants (e.g., phenobarbital, phenytoin): may accelerate vitamin D metabolism, reducing effectiveness. - Glucocorticoids: can impair vitamin D activation and increase bone loss risk. - Orlistat: may decrease absorption of fat‑soluble vitamins including vitamin D.
