Zemplar (paricalcitol) Injection is a man-made active form of vitamin D used in patients with long-term kidney disease to treat or prevent high levels of parathyroid hormone. Too much parathyroid hormone can cause serious problems such as bone disorders. This medication is available in generic form. Common side effects include headache, nausea, chills, or fever.
The recommended initial dose of Zemplar is 0.04 mcg/kg to 0.1 mcg/kg (2.8 - 7 mcg) administered as a bolus dose no more frequently than every other day at any time during dialysis. Zemplar may interact with products that contain aluminum/magnesium (e.g., certain antacids, phosphate binders), corticosteroids, digoxin, calcium supplements, other products that contain vitamin D or phosphate, nefazodone, telithromycin, azole antifungals, antibiotics, protease inhibitors, thiazide diuretics, or drugs that cause drowsiness (antihistamines, anti-seizure drugs, medicine for sleep or anxiety, muscle relaxants, narcotics, psychiatric medicines). Tell your doctor all medications and supplements you use. During pregnancy, Zemplar should be used only when prescribed. It is unknown if Zemplar passes into breast milk. Consult your doctor before breastfeeding.

Zemplar FDA Prescribing Information: Side Effects
Zemplar has been evaluated for safety in clinical studies in 609 CKD Stage 5 patients. In four, placebo-controlled, double-blind, multicenter studies, discontinuation of therapy due to any adverse event occurred in 6.5% of 62 patients treated with Zemplar (dosage titrated as tolerated, see CLINICAL PHARMACOLOGY - Clinical Studies) and 2.0% of 51 patients treated with placebo for 1 to 3 months. Adverse events occurring in the Zemplar group at a frequency of 2% or greater and with an incidence greater than that in the placebo group, regardless of causality, are presented in the following table:
Adverse Event Incidence Rates for All Treated Patients In
All Placebo-Controlled Studies
|Adverse Event||Zemplar (n = 62) %||Placebo (n = 51) %|
|General Disorders and Administration Site Conditions|
|Infections and Infestations|
|Musculoskeletal and Connective Tissue Disorders|
A patient who reported the same medical term more than once was counted only once for that medical term.
Safety parameters (changes in mean Ca, P, Ca × P) in an open-label safety study up to 13 months in duration support the long-term safety of Zemplar in this patient population (see Clinical Studies).
