ZEMPLAR IV: adult dialysis dosing and laboratory-directed titration
What matters first
Product: Adult IV ZEMPLAR for secondary hyperparathyroidism in CKD on dialysis. Not oral capsules, and not a pediatric titration protocol.
- Renal action / finding
- Adult start 0.04-0.1 mcg/kg IV during dialysis.
- Evidence or dialysis limit
- Adult IV only. The pediatric 0.04 mcg/kg increment is NOT the adult titration increment.
- Monitoring / application
- Use the full PTH-response table; monitor calcium and PTH.
- Product / population
- Adult IV ZEMPLAR for secondary hyperparathyroidism in CKD on dialysis. Not oral capsules, and not a pediatric titration protocol.
- Renal measure
- Dialysis-dependent CKD; titration uses calcium and intact PTH, not a CrCl dose band

Sections 2.1 and 2.2, adult titration Table 1
| Situation | Source-specific guidance |
|---|---|
| Adult start | 0.04-0.1 mcg/kg IV; no more often than every other day. |
| Adult upward titration when indicated | 2-4 mcg every 2-4 weeks; follow the PTH response table. |
| Laboratory safety | Calcium frequently; PTH every 2-4 weeks after dose changes. |

Before starting, calcium must not exceed the normal upper limit. Adult starting dose: 0.04-0.1 mcg/kg IV during dialysis, no more often than every other day. If PTH remains above target and rises or falls less than 30%, increase by 2-4 mcg every 2-4 weeks. A 30-60% fall above target supports no change; a greater than 60% fall calls for reduction using clinical judgment. Maximum adult daily dose is 0.24 mcg/kg. Follow calcium frequently and PTH every 2-4 weeks after starting or adjusting. Reduce/hold for persistent low PTH or high calcium.
