Always read the label. If you have any queries about the correct way to use this product, please ask your doctor. Individual results may vary.


  • Renal impairment: Patients with severe renal impairment are unable to convert ergocalciferol to its active form.
  • Patients should follow dietary recommendations for dairy products and avoid sudden increases in dietary calcium intake as this may cause hypercalcemia. Concurrent administration of vitamin D substances and calcium supplement should be avoided because of risk of hypercalcaemia, unless the patient’s dietary intake is inadequate. Ergocalciferol should be stopped immediately if hypercalcemia occurs.

If you have any concerns, please speak with your doctor.
