• Vitamin D (ergocalciferol-D2, cholecalciferol-D3, alfacalcidol) is a fat-soluble vitamin that helps your body absorb calcium and phosphorus. Having the right amount of vitamin D, calcium, and phosphorus is important for building and keeping strong bones.
• Vitamin D is made by the body when skin is exposed to sunlight. Sunscreen, protective clothing, limited exposure to sunlight, dark skin, and age may prevent getting enough vitamin D from the sun. 

• Vitamin D is used to treat and prevent bone disorders (such as rickets, osteomalacia).
• Vitamin D with calcium is used to treat or prevent bone loss (osteoporosis).
• Vitamin D is also used with other medications to treat low levels of calcium or phosphate caused by certain disorders (such as hypoparathyroidism, pseudohypoparathyroidism, familial hypophosphatemia). 
• It may be used in kidney disease to keep calcium levels normal and allow normal bone growth. 
• Vitamin D drops (or other supplements) are given to breast-fed infants because breast milk usually has low levels of vitamin D.

• At normal doses usually has no side effects.

• Before using this medication, tell your doctor or pharmacist your medical history, especially of: high calcium/vitamin D levels (hypercalcemia/hypervitaminosis D), difficulty absorbing nutrition from food (malabsorption syndrome), kidney disease, liver disease.
