Current dosage recommendations for doxercalciferol in patients undergoing peritoneal dialysis are the same as those for hemodialysis patients, according to the manufacturer.
Weekly monitoring of serum calcium, phosphorus, and iPTH levels is recommended during doxercalciferol titration. In the event of hypercalcemia or hyperphosphatemia or should the product of serum calcium and phosphorus concentrations exceed 70, doxercalciferol should be withheld. Following an appropriate calcium and/or phosphate reduction, therapy should be continued at an oral dosage at least 2.5 mcg or intravenous dosage at least 1 mcg less than the last administered dose.
