Indication and Limitations of Use
Rayaldee® (calcifediol) extended-release 30 mcg capsules is indicated for the
treatment of secondary hyperparathyroidism in adults with stage 3 or 4 chronic kidney disease and serum total 25-hydroxyvitamin D levels less than 30
ng/mL.
Rayaldee is not indicated in patients with stage 5 chronic kidney disease or end-stage renal disease on dialysis.
Important Safety Information:
-
Hypercalcemia: Excessive administration of vitamin D
compounds, including Rayaldee, can cause hypercalcemia and hypercalciuria.
Severe hypercalcemia due to substantial overdosage of vitamin D and its
metabolites may require emergency attention. Patients should be informed about the symptoms of elevated calcium.
-
Digitalis toxicity: Potentiated by hypercalcemia of any cause.
Monitor serum calcium and signs and symptoms of digitalis toxicity more frequently when initiating or adjusting the dose
of Rayaldee.
-
Adynamic Bone Disease: Monitor for abnormally low levels of intact parathyroid hormone (iPTH) levels when using Rayaldee, and adjust dose if needed.
-
The most common adverse reactions (≥3% and more frequent than placebo) were anemia, nasopharyngitis, increased blood creatinine, dyspnea, cough, congestive heart failure and constipation.
-
Care should be taken while dosing Rayaldee with cytochrome P450 inhibitors, thiazides, cholestyramine or drugs stimulating microsomal hydroxylation due to the potential for drug interactions.
-
Serum calcium should be below 9.8 mg/dL before initiating treatment.
-
Monitor serum calcium, phosphorus, 25-hydroxyvitamin D and iPTH 3 months after starting therapy or changing dose.
