Asymptomatic or Ca <12 mg/dL
- Does not require immediate treatment
- Advise to avoid factors that can aggravate hypercalcemia (thiazide diuretics, Li, volume depletion, prolonged inactivity, high Ca diet)
Mildly symptomatic Ca 12-14 mg/dL
- May not require immediate therapy; however, an acute rise may cause symptoms necessitating treatment as described for severe hypercalcemia (see below)
Symptomatic or Severe hypercalcemia (Ca >14 mg/dL)
- Pts are likely dehydrated and require saline hydration as initial therapy
Hydration
- Isotonic saline at 200-300 mL/hour; adjust to maintain urine output at 100-150 mL/hour
Calcitonin
- Consider adding calcitonin 4 units/kg SC or IV q12hr in patients w/ Ca >14 mg/dL (3.5 mmol/L) who are also symptomatic (lowers Ca w/in 2-4hr)
- Tachyphylaxis limits use long term, but is a great choice for emergent cases
Bisphosphonates
Give for severe hypercalcemia due to excessive bone resorption (lowers Ca within 12-48hr)
- Pamidronate 90mg IV over 24 hours OR
- Zoledronate 4mg IV over 15 minutes
- Caution in renal failure, though bisphosphonates have been safely used in pts with pre-existing renal failure[1]
Electrolyte Repletion
- Correct hypokalemia
- Correct hypomagnesemia
Diuresis
- Furosemide is NOT routinely recommended
- Only consider in patients with renal insufficiency or heart failure and volume overload
Dialysis
Consider if patient:
- Anuric with Renal Failure
- Failing all other therapy
- Severe hypervolemia not amenable to diuresis
- Serum Calcium level >18mg/dL
Corticosteroids
Decrease Ca mobilization from bone and are helpful with steroid-sensitive tumors (e.g. lymphoma, MM)
- Prednisone 60mg PO daily
