🦴 Hypercalcemia Management
This tool guides hypercalcemia management by calcium level, symptoms, and renal function, framing fluids, antiresorptives (bisphosphonate/denosumab), calcitonin, and special-etiology therapy.
Hypercalcemia Management
Calcium level
Symptoms
Renal impairment or bisphosphonate contraindication
When to use
Use to scale treatment: mild asymptomatic disease is managed by cause and precipitant avoidance, while moderate-severe or symptomatic hypercalcemia gets IV saline first-line plus antiresorptive and rapid calcitonin.
How it works
Mild asymptomatic → treat cause/avoid precipitants. Moderate-severe/symptomatic → IV normal saline (urine output ≥ 100 mL/h, loop diuretic only after fluids) + zoledronic acid (or denosumab if renal impairment) + calcitonin for rapid lowering.
Key points
- Never give a loop diuretic before adequate fluid resuscitation — it worsens calcium handling; reserve it for volume overload after rehydration. (original synthesis · not guideline verbatim)
- Denosumab is preferred when renal impairment or a bisphosphonate contraindication is present, and for refractory/recurrent cases.
- Calcitriol-mediated hypercalcemia (vitamin D toxicity, granulomatous disease, lymphoma) responds to glucocorticoids.
