Kombi-Kalz

Colecalciferol, the active ingredient in Kombi-Kalz, is a Vitamin D3 presented as an oral supplement for supporting calcium metabolism and bone health. It is combined with calcium carbonate, a source of elemental calcium, to address calcium and vitamin D deficiencies in adults. GNH USA supplies Kombi-Kalz as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Kombi‑Kalz is used as a nutritional supplement to address disorders of calcium and vitamin D metabolism. - Calcium deficiency: helps restore normal calcium levels and supports bone mineralisation. - Vitamin D deficiency: provides vitamin D3 to raise serum 25‑hydroxyvitamin D concentrations. - Osteoporosis prevention: contributes to bone density maintenance in at‑risk populations. - Support of bone health: assists overall skeletal strength during ageing or periods of increased demand.

Kombi‑Kalz may cause adverse reactions, most of which are mild and reversible.

Common Side Effects: - Gastrointestinal discomfort: nausea, abdominal bloating or mild cramps. - Constipation or loose stools. - Flatulence. - Mild hypercalcaemia: transient elevation of serum calcium without symptoms. - Headache.

Serious or Rare Side Effects: - Significant hypercalcaemia: fatigue, polyuria, cardiac arrhythmia. - Nephrolithiasis (kidney stones) due to calcium excess. - Allergic reactions: rash, pruritus, facial swelling. - Hypervitaminosis D: severe nausea, vomiting, weakness. - Severe abdominal pain requiring medical evaluation.

Before initiating Kombi‑Kalz, consider the following safety measures. - Assess baseline calcium and vitamin D status: obtain serum levels to guide supplementation. - Monitor renal function: adjust dose in patients with impaired kidney clearance. - Avoid excessive supplemental calcium: risk of hypercalcaemia and vascular calcification. - Use with caution in hyperparathyroidism or granulomatous diseases. - Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Kombi‑Kalz can interact with several medicines; awareness of the interaction level helps manage risk.

Major Interactions (Avoid): - Thiazide diuretics: may increase serum calcium and precipitate hypercalcaemia. - High‑dose vitamin A supplements: combined excess can lead to hypervitaminosis D. - Digitalis glycosides: elevated calcium may enhance cardiac toxicity.

Moderate Interactions (Monitor Closely): - Orlistat: reduces absorption of fat‑soluble vitamin D, potentially lowering efficacy. - Antacids containing aluminium or magnesium: may bind calcium and reduce its bioavailability. - Systemic corticosteroids: increase calcium loss, possibly requiring dose adjustment.
