1 What is Zemplar?

Brand: Zemplar

Generic: Paricalcitol

Zemplar is a calcitriol analog used for the treatment and prevention of hyperparathyroidism in patients with chronic kidney disease who are on dialysis.

Hyperparathyroidism is a condition that is caused when the parathyroid glands overproduce parathyroid hormone which controls the concentrations of calcium and phosphorus in your blood.

This drug helps lower the amount of PTH which lowers the calcium and phosphorus concentrations. This drug requires a prescription.
