What is calcifediol?

What is calcifediol?

Calcifediol is a vitamin D3. Vitamin D is important for the absorption of calcium from the stomach and for the functioning of calcium in the body.

Calcifediol is used to treat secondary hyperparathyroidism (overactive parathyroid glands) in adults who have stage 3 or 4 chronic kidney failure and low vitamin D levels. Calcifediol is not for people who are receiving dialysis.

Calcifediol may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before taking calcifediol?

Tell your doctor if you have ever had:

  • heart problems; or
  • high levels of calcium in your blood (hypercalcemia).

Tell your doctor if you are pregnant or plan to become pregnant. It is not known whether calcifediol will harm an unborn baby. However, having chronic kidney disease during pregnancy may cause complications such as miscarriage, premature birth, low birth weight, stillbirth, or eclampsia (dangerously high blood pressure that can lead to medical problems in both mother and baby). The benefit of treating kidney disease may outweigh any risks to the baby.

If you are breastfeeding, tell your doctor if you notice vomiting, constipation, weight loss, or seizures in the nursing baby.
