About Ergocalciferol Capsules,

What is this medication? Ergocalciferol capsules, also known as vitamin D2, are a prescription-strength supplement used to treat and prevent vitamin D deficiency. This medication is essential for individuals who cannot maintain adequate levels of vitamin D through their diet or natural sunlight exposure. It works by helping the body effectively absorb calcium and phosphorus from the intestines, which are the primary minerals required for building and maintaining strong, healthy bones. Beyond addressing basic deficiencies, these capsules are prescribed for specific medical conditions including hypoparathyroidism, refractory rickets, and familial hypophosphatemia. By regulating the amount of calcium and phosphate in the blood, ergocalciferol helps prevent bone loss and manages disorders involving the parathyroid glands. Patients typically undergo regular blood tests while taking this medication to ensure that their mineral levels stay within a safe and therapeutic range as directed by their healthcare provider.

Prescribing information

From the FDA-approved label for Ergocalciferol Capsules,. Official source: DailyMed (NLM) · Label effective Jan 8, 2025

Indications and usage
INDICATIONS AND USAGE Ergocalciferol Capsules are indicated for use in the treatment of hypoparathyroidism, refractory rickets, also known as vitamin D resistant rickets, and familial hypophosphatemia.
Dosage and administration
DOSAGE AND ADMINISTRATION THE RANGE BETWEEN THERAPEUTIC AND TOXIC DOSES IS NARROW. Vitamin D Resistant Rickets : 12,000 to 500,000 IU units daily. Hypoparathyroidism: 50,000 to 200,000 IU units daily concomitantly with calcium lactate 4 g, six times per day. DOSAGE MUST BE INDIVIDUALIZED UNDER CLOSE MEDICAL SUPERVISION. Calcium intake should be adequate. Blood calcium and phosphorus determinations must be made every 2 weeks or more frequently if necessary. X-rays of the bones should be taken every month until condition is corrected and stabilized.
Contraindications
CONTRAINDICATIONS Ergocalciferol Capsules are contraindicated in patients with hypercalcemia, malabsorption syndrome, abnormal sensitivity to the toxic effects of vitamin D, and hypervitaminosis D.
Warnings
WARNINGS Hypersensitivity to vitamin D may be one etiologic factor in infants with idiopathic hypercalcemia. In these cases vitamin D must be strictly restricted. Keep out of the reach of children.
Drug interactions
Drug Interactions Mineral oil interferes with the absorption of fat-soluble vitamins,including vitamin D preparations. Administration of thiazide diuretics to hypoparathyroid patients who are concurrently being treated with Ergocalciferol Capsules may cause hypercalcemia.
Adverse reactions
ADVERSE REACTIONS Hypervitaminosis D is characterized by effects on the following organ system: Renal: Impairment of renal function with polyuria, nocturia, polydipsia, hypercalciuria, reversible azotemia, hypertension, nephrocalcinosis, generalized vascular calcification, or irreversible renal insufficiency which may result in death. CNS: Mental retardation. Soft Tissues: Widespread calcification of the soft tissues, including the heart, blood vessels, renal tubules, and lungs. Skeletal: Bone demineralization (osteoporosis) in adults occurs concomitantly. Decline in the average rate of linear growth and increased mineralization of bones in infants and children (dwarfism) vague aches, stiffness, and weakness. Gastrointestinal: Nausea, anorexia, constipation. Metabolic: Mild acidosis, anemia, weight loss.
Use in pregnancy
Pregnancy Pregnancy Category C Animal reproduction studies have shown fetal abnormalities in several species associated with hypervitaminosis D. These are similar to the supravalvular aortic stenosis syndrome described in infants by Black in England (1963). This syndrome was characterized by supravalvular aortic stenosis, elfin facies, and mental retardation. For the protection of the fetus, therefore, the use of vitamin D in excess of the recommended dietary allowance during normal pregnancy should be avoided unless, in the judgment of the physician, potential benefits in a specific, unique case outweigh the significant hazards involved. The safety in excess of 400 IU of vitamin D daily during pregnancy has not been established.
