What is Colecalciferol?
Colecalciferol, the active ingredient in Oleovit D3, is a vitamin D presented as a supplement for oral use. It supports calcium metabolism and bone health in individuals with deficiency or at risk of low vitamin D levels.
GNH USA supplies Oleovit D3 as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.
What is Colecalciferol used for?
Oleovit D3 (colecalciferol) is used to correct or prevent vitamin D deficiency, a condition that affects calcium balance and bone health. - Vitamin D deficiency: restores adequate serum 25‑hydroxyvitamin D concentrations. - Osteomalacia in adults: aids mineralisation of bone matrix. - Rickets in children: supports normal bone growth and mineralisation. - Secondary hypocalcaemia associated with hypoparathyroidism: helps maintain calcium levels. - Chronic kidney disease‑related low vitamin D: supplements the reduced endogenous synthesis.
What are the side effects of Colecalciferol?
Adverse reactions to Oleovit D3 are generally uncommon but may occur.
Common Side Effects: - Hypercalcaemia: elevated blood calcium levels. - Nausea or gastrointestinal discomfort. - Headache. - Fatigue. - Mild rash or itching.
Serious or Rare Side Effects: - Severe hypercalcaemia with cardiac arrhythmia. - Nephrolithiasis (kidney stones). - Hypercalciuria leading to renal impairment. - Acute pancreatitis. - Anaphylactic reaction. - Persistent vomiting or dehydration.
What precautions apply to Colecalciferol?
When using Oleovit D3, consider the following safety measures. - Monitor serum calcium and 25‑hydroxyvitamin D levels: adjust dose if elevated. - Avoid use in patients with known hypercalcaemia: risk of worsening calcium overload. - Caution in renal impairment: reduced conversion to active form may require monitoring. - Pregnant or breastfeeding women: use only if clearly indicated by a healthcare professional. - Concomitant use with thiazide diuretics: may increase calcium retention. - Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.
What does Colecalciferol interact with?
Oleovit D3 may interact with several medicines, altering calcium balance or vitamin D metabolism.
Major Interactions (Avoid): - Thiazide diuretics: can exacerbate hypercalcaemia. - Vitamin D intoxication from high‑dose supplements. - Granulomatous diseases (e.g., sarcoidosis) treated with steroids: increased conversion to active vitamin D.
Moderate Interactions (Monitor Closely): - Anticonvulsants (phenytoin, phenobarbital): may increase vitamin D catabolism. - Corticosteroids: can reduce vitamin D effectiveness. - Orlistat: may decrease absorption of fat‑soluble vitamins.",
