What is the most important information I should know about doxercalciferol?

Follow all directions on your medicine label and package. Tell each of your healthcare providers about all your medical conditions, allergies, and all medicines you use.

What is doxercalciferol?

Doxercalciferol is a synthetic (man-made) form of vitamin D. Vitamin D is important for the absorption of calcium from the stomach and for the functioning of calcium in the body.

Doxercalciferol is used to maintain healthy blood levels of calcium and intact parathyroid hormone (iPTH) in people with chronic kidney disease who may also be on dialysis.

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

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

You should not take doxercalciferol if you have high levels of vitamin D or calcium in your body.

To make sure doxercalciferol is safe for you, tell your doctor if you have:

  • liver disease;
  • a vitamin D deficiency; or
  • high levels of calcium in your blood (hypercalcemia).

It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant. Your dose needs may be different during pregnancy.

It is not known whether doxercalciferol passes into breast milk. However, other forms of vitamin D can pass into breast milk and could harm a nursing baby. You should not breast-feed while taking doxercalciferol.
