Rayaldee (generic name: calcifediol), a vitamin D3 analog, is used for the treatment of secondary hyperparathyroidism (SHPT) in stage 3 or 4 chronic kidney disease (CKD).

Patients with CKD and SHPT have an imbalance of calcium and phosphorus levels in their body. When calcium levels in the body get too low, parathyroid hormone (PTH) is released from the parathyroid gland. PTH tells the body to release calcium from the bone to help replenish calcium, but this can make bones weak and brittle.
