Generic Name: zoledronic acid (ZOE-le-DRON-ik AS-id)
Brand Name: Zometa
Zoledronic acid is used for:
Treating high blood calcium levels caused by cancer. It is also used with other medicines to treat patients with certain types of cancer. It may also be used for other conditions as determined by your doctor.
Zoledronic acid is a bisphosphonate. It works by decreasing the breakdown of bone. This reduces the amount of calcium that is released into the blood from bones and helps to lower your blood calcium level.
Do NOT use zoledronic acid if:
- you are allergic to any ingredient in zoledronic acid
- you have severe kidney problems and you also have a certain type of cancer (multiple myeloma) or cancer that has moved into the bones from other parts of the body
- you are taking another medicine that contains zoledronic acid or any other bisphosphonate (eg, alendronate)
Contact your doctor or health care provider right away if any of these apply to you.
