Why is ROCALTROL (Calcitriol) prescribed?
ROCALTROL (Calcitriol) is a synthetic form of vitamin D used to treat people on
dialysis who have hypocalcemia (abnormally low blood calcium levels)
and resulting bone damage. ROCALTROL (Calcitriol) is also prescribed to treat low
blood calcium levels in people who have hypoparathyroidism (decreased
functioning of the parathyroid glands). When functioning correctly,
these glands help control the level of calcium in the blood.
ROCALTROL (Calcitriol) is also prescribed for hyperparathyroidism (increased functioning
of the parathyroid glands) and resulting bone disorders in people with
kidney disease who are not yet on dialysis. Most important fact about ROCALTROL (Calcitriol)

harmful. If you are already taking any medications containing calcium
or calcium supplements, make sure you doctor knows about it. How should you take ROCALTROL (Calcitriol)?
