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 reduce elevated intact parathyroid hormone (iPTH) levels in the treatment of secondary hyperparathyroidism in patients undergoing chronic renal dialysis. Doxercalciferol may also be used for purposes other than those listed in this medication guide.
Doxercalciferol is a synthetic vitamin D2 analog which undergoes metabolic activation to form a naturally occurring, biologically active form of the vitamin. Hectorol is supplied in form of capsules, each which contains fractionated triglyceride of coconut oil, ethanol, as well as butylated hydroxyanisole.
