Rocaltrol contains the generic ingredient calcitriol, which belongs to a group of medications called D3 metabolites. Rocaltrol is used to treat calcium deficiency or hypocalcemia in patients with certain disorders.
Doctors prescribe Rocaltrol to people with chronic kidney failure who are undergoing dialysis or to patients who have underactive parathyroid glands. Rocaltrol can also be used to treat a type of bone disease called rickets.
Normally, vitamin D is converted by the liver and kidneys to its active form calcitriol, which controls the absorption of calcium and phosphorus in the body. Sometimes people with reduced functioning of the kidneys or parathyroid glands cannot convert enough vitamin D to calcitriol. Rocaltrol works by directly increasing the amount of active vitamin D in the body.
Your doctor may start you on a low dose and increase it slowly to find the best dose for you. Follow your doctor's directions carefully. The recommended starting dose is 0.25mcg per day taken orally. Most patients undergoing hemodialysis respond to dosages between 0.5 and 1mcg/day. Be sure to drink plenty of fluids while taking this medication.
These may not be all the side effects of Rocaltrol.
Do not take this medication if you are allergic to any of its ingredients or if you have high levels of calcium in the blood.
Let your doctor know if you have an allergy to vitamin D, have kidney disease, are undergoing dialysis or have a history of heart problems.
