Drug Information
8 reviews for Calcitriol (Rocaltrol)
Rocaltrol contains Calcitriol.
Calcitriol is the active form of vitamin D. It is used when the body cannot make active vitamin D itself, often because of kidney disease.
It helps control calcium and phosphate levels and keeps bones healthy.
What is it used for?
- Low calcium and bone problems in chronic kidney disease
- Low parathyroid hormone (hypoparathyroidism)
- Rickets that does not respond to normal vitamin D
How does it work?
Normally the kidneys turn vitamin D into its active form, calcitriol. Taking calcitriol directly helps the gut absorb calcium and keeps bones strong.
