Orbical-D3 (Colecalciferol, Calcium Carbonate)

Colecalciferol, the active ingredient in Orbical-D3, is a vitamin D and calcium supplement presented as an oral tablet for oral use. It supports calcium absorption and bone mineralization in individuals with vitamin D or calcium deficiency, and helps maintain skeletal health.

GNH USA supplies Orbical-D3 as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The product complies with EU pharmacopeial standards and is distributed under strict quality assurance protocols. Its consistent batch-to-batch potency ensures reliable supplementation for diverse patient populations.

Orbical-D3 provides vitamin D3 and calcium to address conditions related to mineral deficiency and bone health.

- Vitamin D deficiency: restores normal serum 25‑hydroxyvitamin D concentrations. - Calcium deficiency: contributes to maintaining adequate serum calcium levels. - Osteoporosis risk: supports bone mineral density and reduces bone turnover. - Secondary hyperparathyroidism: helps normalize parathyroid hormone levels. - Post‑menopausal bone loss: assists in preserving skeletal strength.

Orbical-D3 may be associated with several adverse reactions, ranging from mild to serious.

Common Side Effects: - Nausea - Constipation - Abdominal discomfort - Mild hypercalcemia - Headache - Dry mouth

Serious or Rare Side Effects: - Severe hypercalcemia - Kidney stones - Allergic reactions such as rash or angioedema - Hypervitaminosis D - Cardiac arrhythmia

Before initiating Orbical-D3, consider the following precautions.

- Assess baseline calcium and vitamin D levels: check serum concentrations prior to therapy. - Monitor renal function: especially important in patients with chronic kidney disease. - Avoid in hypercalcemia: contraindicated when serum calcium is elevated. - Caution in sarcoidosis or granulomatous disease: risk of excessive vitamin D activity. - Pregnancy and lactation: use only if clearly needed after risk‑benefit assessment. - Store at ambient temperature: keep in the original pack, protect from moisture and light.

Orbical-D3 can interact with several medicines; awareness of the interaction level is essential.

Major Interactions (Avoid): - Thiazide diuretics: may precipitate hypercalcemia. - Excess vitamin A intake: increases risk of hypervitaminosis D. - Lithium therapy: can elevate calcium levels.

Moderate Interactions (Monitor Closely): - Orlistat: reduces absorption of fat‑soluble vitamins including vitamin D. - Anticonvulsants (e.g., phenytoin, phenobarbital): accelerate vitamin D metabolism. - Corticosteroids: may diminish calcium absorption and affect bone health.
