What is dihydrotachysterol?
Dihydrotachysterol is a form of vitamin D. Vitamin D is needed by the body to keep your bones and teeth healthy. It also helps your body absorb and use calcium more efficiently to help protect bones and teeth.
Dihydrotachysterol is used to treat hypocalcemia (lack of calcium in the blood) and hypoparathyroidism (lack of parathyroid hormone in the body).
Dihydrotachysterol may also be used for purposes other than those listed in this medication guide.
