Ergocalciferol / Vitamin D2 (Ergocalciferol) — Uses, Dosage, Side Effects & Safety
Drug class: Vitamin D analog
Overview
Ergocalciferol, also known as Vitamin D2, is a form of vitamin D used to treat or prevent vitamin D deficiency and related conditions such as rickets (softening of bones in children), osteomalacia (softening of bones in adults), and certain types of hypoparathyroidism. It is also used in patients with chronic kidney disease to help maintain healthy calcium and phosphate levels. Vitamin D2 works by helping your body absorb calcium and phosphorus, which are essential for building and maintaining strong bones. It is usually prescribed when dietary intake or sunlight exposure is insufficient, or when the body cannot properly convert vitamin D to its active form. Key points for patients: Take this medication exactly as prescribed, do not exceed the recommended dose, and inform your healthcare provider about all other medications and supplements you are taking. Regular monitoring of blood calcium and vitamin D levels may be necessary.
