Vitamin D3 is contraindicated in all diseases associated with hypercalcaemia. It is also contraindicated in patients with known hypersensitivity to Vitamin D3 (or medicines of the same class) and any of the excipients. It is contraindicated if there is evidence of Vitamin D3 toxicity.

⚡ Side Effects & Adverse Reactions

Generally all nutritional supplements are considered to be safe and well tolerable. However, few most common side effects can generally occur including hypocalcaemia syndrome or calcium intoxication (depending on the severity and duration of hypocalcaemia), occasional acute symptoms include anorexia, headache, nausea, vomiting, abdominal pain or stomach ache and constipation with the administration of colecalciferol.

🛡️ Warnings & Precautions

Plasma-calcium concentration should be monitored at intervals in patients receiving high doses of Vitamin D3, in renal impairment, and during pregnancy & lactation. People using Digoxin and Thiazide Diuretics should consult a health care practitioner before supplementing with Vitamin D3. People with liver or kidney disease, primary hyperthyroidism, lymphoma, tuberculosis and granulomatous disease should consult a health care practitioner before supplementing with Vitamin D3.

🔬 Pharmacology & Mechanism

The active form of Vitamin D3, Calcitriol, exerts its effect by binding to the Vitamin D receptors (VDRs) which are widely distributed through many body tissues.Vitamin D3 has a half life of about 50 days as it is fat soluble.Vitamin D3 is absorbed in the small intestine and bound to specific a-globulins and transported to the liver where it is metabolised to 25-hydroxy Vitamin D3 (Calcidiol). A second hydroxylation to 1,25-dihydroxy Vitamin D3 (Calcitriol) occurs in the kidney. This metabolite is responsible for the vitamin's ability to increase the absorption of calcium. Non-metabolised Vitamin D3 is stored in tissues such as fat and muscle.Vitamin D3 is eliminated via faeces and urine.
