Natemille (Colecalciferol, Calcium Carbonate)

Colecalciferol, the active ingredient in Natemille, is a vitamin D and calcium supplement presented as an oral dosage form for oral use. Together with calcium carbonate, it provides vitamin D3 and calcium to support calcium absorption and bone mineralisation, helping to prevent deficiency states in adults and older individuals.

GNH USA supplies Natemille as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The product complies with EU quality standards and is distributed under strict Good Distribution Practice guidelines.

Natemille is a vitamin D and calcium supplement that acts on mineral metabolism and bone health. - Calcium deficiency: helps restore adequate calcium levels and reduce related symptoms. - Vitamin D deficiency: raises serum 25‑hydroxyvitamin D concentrations to normal ranges. - Bone health support: contributes to bone mineralisation and reduces risk of osteopenia. - Osteoporosis prevention: provides nutrients that aid in maintaining bone density in at‑risk populations.

Adverse reactions may occur with oral vitamin D and calcium supplementation.

Common Side Effects: - Hypercalcaemia: elevated blood calcium levels causing fatigue or mild nausea. - Gastrointestinal upset: abdominal discomfort, bloating or flatulence. - Constipation: reduced bowel movements, especially with calcium carbonate. - Nausea: feeling of sickness after ingestion. - Headache: mild to moderate head pain. - Metallic taste: transient alteration in taste perception.

Serious or Rare Side Effects: - Severe hypercalcaemia: can lead to kidney stones, cardiac arrhythmia or confusion. - Hypervitaminosis D: excessive vitamin D causing tissue calcification. - Allergic reaction: rash, itching, swelling or difficulty breathing. - Acute pancreatitis: rare inflammation of the pancreas. - Renal impairment: worsening kidney function in susceptible individuals. - Calcification of soft tissues: abnormal calcium deposition in organs.

Natemille should be used with consideration of individual health status and monitoring requirements. - Baseline assessment: evaluate serum calcium and vitamin D levels before initiating therapy. - Renal function: use cautiously in patients with impaired kidney function. - Hypercalcaemia: avoid in individuals with known high calcium levels. - Sarcoidosis or granulomatous disease: contraindicated due to risk of excess vitamin D activation. - Pregnancy and lactation: safety not established; consult a healthcare professional. - Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Natemille may interact with other medicines that affect calcium or vitamin D metabolism.

Major Interactions (Avoid): - Thiazide diuretics: increase risk of hypercalcaemia. - Lithium: may potentiate hypercalcaemia. - High‑dose vitamin A: synergistic toxicity leading to hypervitaminosis. - Antacids containing aluminium or magnesium: reduce calcium absorption.

Moderate Interactions (Monitor Closely): - Loop diuretics: may increase calcium loss, requiring monitoring. - Bisphosphonates: concurrent use may affect bone turnover markers. - Corticosteroids: can reduce calcium absorption, necessitating dose adjustment. - Anticonvulsants (e.g., phenytoin): may accelerate vitamin D metabolism. - ACE inhibitors: monitor blood pressure and electrolyte balance.
