DOSING:

  • Hypoparathyroidism: Take 25000 to 200000 IU vitamin D by mouth once daily with 4 grams of calcium lactate 6 times daily.

  • Daily intake of vitamin D: Take 600 IU daily.

DRUG INTERACTIONS: Vitamin D should be used with caution with mineral oil because mineral oil slows down the absorption of Vitamin D and reduces its therapeutic benefits.

Thiazide diuretics like hydrochlorothiazide (Microzide) and chlorthalidone (Thalitone) should be used with caution in people with hypoparathyroid taking Vitamin D, because thiamine diuretics may increase calcium levels.

PREGNANCY: There are no adequate studies done on Vitamin D to determine safe and effective use in pregnant women.

NURSING MOTHERS: Vitamin D enters breast milk. Therefore, it is best to be cautious before using it in nursing mothers.

SIDE EFFECTS: Side effects of Vitamin D are nausea, vomiting, constipation, weight loss, weakness, and increased calcium levels (hypercalcemia).
