What is the dose of Rocaltrol® (calcitriol) for an adult?
Dosage is based on your medical condition and response to therapy. Your doctor may start you on a low dose and adjust the dose slowly to find the best dose for you. Follow your doctor’s directions carefully. Use this medication regularly in order to get the most benefit from it.
Rocaltrol® can be administered orally either as a capsule (0.25 mcg or 0.50 mcg) or as an oral solution (1 mcg/ml).
Rocaltrol® therapy should always be started at the lowest possible dose and should not be increased without careful monitoring of serum calcium.
The effectiveness of Rocaltrol® therapy is predicated on the assumption that each patient is receiving an adequate but not excessive daily intake of calcium. Patients are advised to have a dietary intake of calcium at a minimum of 600 mg daily. The U.S. RDA for calcium in adults is 800 mg to 1200 mg. To ensure that each patient receives an adequate daily intake of calcium, the physician should either prescribe a calcium supplement or instruct the patient in proper dietary measures.
Because of improved calcium absorption from the gastrointestinal tract, some patients on Rocaltrol® may be maintained on a lower calcium intake. Patients who tend to develop hypercalcemia may require only low doses of calcium or no supplementation at all.
What is the dose of Rocaltrol® (calcitriol) for a child?
The dosage has not been established in pediatric patients. It may be unsafe for your child. It is always important to fully understand the safety of the drug before using. Please consult with your doctor or pharmacist for more information.

What should I do if I miss a dose?
