Patient Education

Calcifediol


Calcifediol is used to treat secondary hyperparathyroidism (a condition in which the body produces too much parathyroid hormone [PTH; a natural substance needed to control the amount of calcium in the blood], ) in certain adults with chronic kidney disease (condition in which the kidneys stop working slowly and gradually). Calcifediol is in a class of medications called vitamin D analogs. It works by helping the body to use more of the calcium found in foods or supplements and by regulating the body's production of parathyroid hormone.
