Natecal Vitamine D3 (Colecalciferol, Calcium Carbonate)

Colecalciferol, the active ingredient in Natecal Vitamine D3, is a Vitamin D3 (Colecalciferol) and Calcium supplement presented as an oral tablet for oral use. It helps prevent vitamin D deficiency and supports calcium intake for bone health in adults and children.

GNH USA supplies Natecal Vitamine D3 as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company ensures quality manufacturing in accordance with EU standards.

Natecal Vitamine D3 is used to address nutritional deficiencies related to vitamin D and calcium, supporting skeletal health.

- Vitamin D deficiency: helps restore adequate vitamin D levels, promoting normal calcium absorption and bone metabolism. - Osteopenia or low bone mass: provides calcium to aid bone mineralization and reduce risk of bone loss. - Growth and development in children: supplies essential calcium and vitamin D for proper skeletal development and maintenance.

Natecal Vitamine D3 may cause adverse reactions, most of which are mild and reversible.

Common Side Effects: - Nausea: mild stomach upset after ingestion. - Constipation: reduced bowel movements. - Abdominal discomfort: cramping or bloating. - Flatulence: increased gas production. - Mild hypercalcemia symptoms: fatigue or thirst.

Serious or Rare Side Effects: - Severe hypercalcemia: confusion, cardiac arrhythmia, or renal impairment. - Kidney stones: calcium deposition in the urinary tract. - Allergic reaction: rash, itching, swelling, or difficulty breathing. - Hypervitaminosis D: excessive vitamin D levels leading to tissue calcification. - Anaphylaxis: rare but life‑threatening systemic allergic response.

Before using Natecal Vitamine D3, consider the following safety measures.

- Baseline assessment: evaluate serum vitamin D and calcium levels. - Monitor renal function: avoid excess calcium in patients with kidney disease. - Avoid excessive intake: do not combine with other high‑dose vitamin D or calcium supplements. - Pregnancy and lactation: use only if prescribed after risk‑benefit evaluation. - Known hypersensitivity: discontinue if allergic reactions occur. - Store at ambient temperature: keep in the original pack, protect from moisture and heat.

Natecal Vitamine D3 can interact with several medicines; awareness helps prevent adverse outcomes.

Major Interactions (Avoid): - Thiazide diuretics: may increase calcium retention leading to hypercalcemia. - Calcium‑containing antacids: can cause excessive calcium load. - High‑dose vitamin A supplements: risk of hypervitaminosis D. - Certain anticonvulsants (e.g., phenytoin, phenobarbital): accelerate vitamin D metabolism, reducing efficacy. - Sarcoidosis or granulomatous diseases: heightened conversion of vitamin D to active form.

Moderate Interactions (Monitor Closely): - Loop diuretics: may increase calcium excretion, requiring monitoring. - Corticosteroids: can impair vitamin D metabolism, necessitating dose adjustment. - ACE inhibitors: occasional alterations in calcium handling. - Statins: rare reports of altered vitamin D levels. - Bisphosphonates: concurrent use may affect calcium balance.
