What is Parsabiv (iv paricalcitol) used for?
Parsabiv is the brand name for paricalcitol, given by intravenous (IV) injection. It is used to treat secondary hyperparathyroidism in people with chronic kidney disease (CKD), typically those on dialysis. Its role is to lower parathyroid hormone (PTH) levels.
How does Parsabiv IV work?
Paricalcitol is a vitamin D receptor activator. By acting on vitamin D receptors in the body, it helps reduce PTH production and release.
How is Parsabiv IV given?
Parsabiv IV is administered by a clinician, usually as a scheduled dialysis-related dose. The dose is adjusted based on PTH lab results and clinical response.
Common side effects people ask about with Parsabiv IV
Patients and clinicians commonly monitor for effects related to changes in calcium/phosphate balance, since vitamin D–type therapies can affect mineral metabolism. Side effects discussed in clinical use often include:
- Low or high calcium-related issues (hypocalcemia risk is a key monitoring concern)
- Nausea or dizziness
- Lab abnormalities that require dose adjustment
What monitoring is required while on Parsabiv IV?
Monitoring typically includes:
- PTH
- Serum calcium
- Phosphorus (and related mineral markers)
Dose adjustments are made to keep PTH in target range while avoiding problematic calcium/phosphate levels.
Is Parsabiv the same as Zemplar or other paricalcitol options?
Parsabiv and other paricalcitol products are in the same drug class (paricalcitol/vitamin D receptor activators), but they may differ by formulation (IV vs oral) and dosing schedules. Switching between products should follow the prescriber’s conversion and monitoring plan.
