Warnings and precautions

Consult your doctor or pharmacist before taking colecalciferol:

• If you are taking certain medicines used to treat heart disorders (e.g., cardiac glycosides, such as digoxin).
• If you have sarcoidosis (a disorder of the immune system that can cause an increase in Vitamin D levels in the body).
• If you are taking other medicines that contain Vitamin D, or if you take foods or milk enriched with Vitamin D.
• If you are likely to have high exposure to sunlight while taking this medicine.
• If you take additional calcium supplements, as you may develop kidney stones. Your doctor will monitor your blood calcium levels to ensure they are not too high while taking colecalciferol.
• If you are taking simultaneous calcium or phosphate supplements, as there is an increased risk of high blood calcium levels (hypercalcemia).
• If you have kidney problems or any kidney disease. Your doctor may want to measure your blood and urine calcium levels.

Your doctor should monitor your blood calcium level with laboratory tests if you take a dose equivalent to a daily dose of Vitamin D3 greater than 1,000 UI for a prolonged period.

Other medicines and Colecalciferol Gebro

Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines. This is especially important if you are taking:

• Medicines that act on the heart or kidneys, such as cardiac glycosides (e.g., digoxin) or diuretics (e.g., bendroflumethiazide). When taken at the same time as Vitamin D3, these medicines can cause a significant increase in blood and urine calcium levels.
• Medicines that contain Vitamin D or if you take foods rich in Vitamin D, such as some types of milk enriched with Vitamin D.
• Actinomycin (a medicine used to treat some forms of cancer) and imidazole antifungals (e.g., clotrimazole and ketoconazole, medicines used to treat fungal diseases). These medicines can affect how your body processes Vitamin D3.
• The following medicines, as they may interfere with the effect or absorption of Vitamin D3:
• • antiepileptic medicines (anticonvulsants), barbiturics;
  • glucocorticoids (steroid hormones such as hydrocortisone or prednisolone). These medicines can reduce the effect of Vitamin D3;
  • medicines that lower cholesterol levels in the blood (such as cholestyramine or colestipol);
  • certain weight loss medicines that reduce the amount of fat absorbed by the body (e.g., orlistat);
  • certain laxatives (such as liquid paraffin).
