Overview

The mainstay of therapy for vitamin D deficiency is vitamin D, either vitamin D2 (ergocalciferol) or vitamin D3 (cholecalciferol).

Medical therapy

There are two major forms of vitamin D; ergocalciferol (vitamin D2), cholecalciferol (vitamin D3). A systematic review and meta-analysis of Tripkovic L et al. in 2011, indicated that vitamin D3 compared to vitamin D2 is more effective to raise the serum level of 25OHD and is preferred for treatment and prevention. [1]

  • Task Force prepared a clinical guideline for the treatment of vitamin D deficiency to reach and sustain a serum 25(OH)D level of 30 ng/ml.[2]
Age Loading dose Alternative dose Maintenance dose
0-1 y 2000 IU/d orally for 6 weeks 50,000 IU/w orally for 6 weeks 400-1000 IU/d
1-18 y 2000 IU/d orally for 6 weeks 50,000 IU/w orally for 6 weeks 600-1000 IU/d
Adults 50,000 IU/w orally for 8 weeks 6000 IU/d orally for 6 weeks 1500–2000 IU/d
Nursing home residents 50,000 IU/three times per week for 1 month 100,000 IU of vitamin D every 4 months
High risk patients* 6000-10,000 IU/d 3000–6000 IU/d

High risk patients include African American, obese, patients with malabsorption syndromes and who are on anticonvulsants.

  • The American Academy of Pediatrics (AAP) recommends an initial phase of treatment with high dose of vitamin D for 2-3 months to treat vitamin D deficiency rickets. The recommended dose is 1000 IU/d in neonates, 1000-5000 IU/d in infants, and 5000 IU/d for children over 1-year-old. [3]

After raising the serum 25 OHD levels to 30 ng/ml, a maintenance dose of 400 IU/d is required for all age groups. Higher maintenance dose (800 IU/d) might be needed in at risk groups. [4]

  • An alternative strategy for treatment, also known as stoss therapy, is a single dose therapy in patients over 1-month-old. 100,000 – 600,000 IU of ergocalciferol orally single dose followed by maintenance therapy is recommended, especially in noncompliant patients. [5]

Special circumstances

  • Patients on anticonvulsant drugs are at risk of vitamin D deficiency. If osteopenia occurs, treatment with 2000-4000 IU/d must be started. In case of osteomalacia, a larger dose of vitamin D, 5000-15000 IU/d is required. [6]
