Vitamin D Deficiency and Dependency
Treatment of Vitamin D Deficiency and Dependency
Type I hereditary vitamin D–dependent rickets responds to 1,25-dihydroxyvitamin D 1 to 2 mcg orally once a day. Some patients with type II hereditary vitamin D–dependent rickets respond to very high doses (eg, 10 to 24 mcg/day) of 1,25-dihydroxyvitamin D; others require long-term infusions of calcium.
