Welcome to Hectorol

What is Hectorol?

Hectorol (doxercalciferol capsules and injection) is a prescription vitamin D hormone that is a treatment for secondary hyperparathyroidism in patients with Stage 3 or Stage 4 chronic kidney disease (capsules) and in patients with chronic kidney disease on dialysis (capsules and injection). Hectorol helps provide your body with consistent levels of vitamin D.

Why Do I Need Hectorol?

Your doctor has prescribed Hectorol to help control your secondary hyperparathyroidism. Since Hectorol does not need the kidneys to begin working, it can help increase the vitamin D in your body and lower your parathyroid hormone. Hectorol is different from over the counter vitamin D supplements. When you have chronic kidney disease, over-the-counter supplements and natural sources of vitamin D may not lower your parathyroid hormone level because they need your kidneys to work.

Ask your doctor what a healthy parathyroid hormone range is for your body and what your parathyroid hormone level should be. By taking Hectorol, you are helping to control your parathyroid hormone levels and maintaining the right balance of calcium and phosphorus in your body.
