Generic Name: zoledronic acid (ZOE-le-DRON-ik AS-id)
Brand Name: Reclast
Zoledronic acid is used for:
Treating and preventing osteoporosis (weak bones) in women who are past menopause. It is also used to help build bone in men with osteoporosis. It is also used to treat and prevent osteoporosis in certain patients treated with corticosteroids (eg, prednisone). It may also be used to treat Paget disease or 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 or to any other bisphosphonate (eg, alendronate)
- you have severe kidney problems or recent worsening of kidney function
- you have low blood calcium levels
- you are using another medicine that contains zoledronic acid
Contact your doctor or health care provider right away if any of these apply to you.
