1. What is Aldexina and what is it used for

Aldexina contains the active substance colecalciferol (Vitamin D3). Vitamin D3 can be found in some foods and is produced by the body when the skin is exposed to sunlight. Vitamin D helps the body absorb calcium in the kidneys and intestines, which helps form bones. A deficiency of Vitamin D is the main cause of rickets (poor bone mineralization in children) and osteomalacia (inadequate bone mineralization in adults).

Colecalciferol is used to prevent and treat Vitamin D deficiency in adults.

  • you have high levels of Vitamin D3 in your blood (hypervitaminosis D)
  • you are allergic to peanuts or soy, as it contains soybean oil.

Warnings and Precautions

Consult your doctor, pharmacist, or nurse before taking colecalciferol if you:

  • are being treated with certain heart medications (e.g., cardiac glycosides, such as digoxin)

  • have kidney disease or tend to form kidney stones. Your doctor may want to monitor your calcium levels in your blood and urine
  • your doctor should monitor your calcium levels in your blood through laboratory tests if your daily intake of Vitamin D3 exceeds 1,000 IU for a prolonged period.

Other Medicines and Aldexina

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

  • medicines for heart or kidney disease, such as cardiac glycosides (e.g., digoxin) or diuretics (e.g., bendroflumethiazide). When these medicines are used at the same time as Vitamin D3, they can cause a significant increase in calcium levels in your blood and urine

  • the following medicines, as they may interfere with the effect or absorption of Vitamin D3:
    • antiepileptic medicines (anticonvulsants), barbiturates;
    • glucocorticoids (steroid hormones such as hydrocortisone or prednisolone), as they may reduce the effect of Vitamin D3;
    • medicines that lower cholesterol levels in your blood (such as cholestyramine or colestipol);
    • certain medicines used to lose weight by reducing fat absorption (e.g., orlistat);
    • certain laxatives (such as liquid paraffin).
