GlobalRPh RX List - ZOMETA
- Product / population
- Adult ZOMETA oncology indications; not RECLAST osteoporosis/Paget dosing.
- Renal measure
- Cockcroft-Gault CrCl for oncology reduction; a separate serum-creatinine criterion for hypercalcemia.
RX mirror: this is not independent corroboration of its underlying label. Check dated-label and formulation limitations.
Renal dosing, restrictions and evidence limits
For myeloma or bone metastases, total doses every three to four weeks are 4 mg at CrCl above 60, 3.5 mg at 50-60, 3.3 mg at 40-49, and 3 mg at 30-39 mL/min, infused over at least 15 minutes. These reductions do not create a regimen below 30. Check creatinine before each dose. In the source trials, hold for a rise of 0.5 mg/dL with normal baseline creatinine or 1 mg/dL with abnormal baseline; resume when within 10% of baseline. Hypercalcemia of malignancy is a different pathway: the source uses 4 mg and no initial reduction for its mild/moderate group with serum creatinine below 4.5 mg/dL. Do not transfer that serum-creatinine criterion to bone-metastasis treatment or RECLAST.
