Ergocalciferol (Deltalin, Eli Lilly and Company) is a form of Vitamin D, also called vitamin D2. It is created from viosterol, which in turn is created when ultraviolet light activates ergosterol.
Ergocalciferol is a white, colorless crystal, insoluble in water, soluble in organic solvents, and slightly soluble in vegetable oils.
Ergocalciferol is vitamin D2. Vitamin D is important for the absorption of calcium from the stomach and for the functioning of calcium in the body.
Ergocalciferol is used to treat hypoparathyroidism (decreased functioning of the parathyroid glands).
Ergocalciferol is also used to treat rickets (softening of the bones caused by vitamin D deficiency) or low levels of phosphate in the blood (hypophosphatemia).
Ergocalciferol may also be used for other purposes not listed in this medication guide.
Ergocalciferol is also used to treat low levels of calcium in the blood caused by insufficient levels of parathyroid hormone, and in a bone disease that occurs when the kidneys do not maintain the proper levels of calcium and phosphate in the blood (renal osteodystrophy).
