- Separate from calcium supplements
- NSAIDs increase GI risk
No liver adjustment needed.
A powerful yearly infusion that suppresses bone resorption.
- Flu-like symptoms
- Low calcium levels
- Kidney strain if dehydrated
- NSAIDs may increase renal risk
- Loop diuretics increase hypocalcemia risk
Hydration required before infusion.
Blocks RANK-L to prevent osteoclast activation and bone loss.
