Zoledronic acid (Zoledronate) (Zoledronic acid) — Uses, Dosage, Side Effects & Safety

Drug class: Bisphosphonate; Bone resorption inhibitor

Overview

Zoledronic acid (Zoledronate) is a medication used to treat and prevent bone loss in conditions such as osteoporosis, Paget's disease of bone, and bone complications from certain cancers (like multiple myeloma and bone metastases). It is also used to lower high blood calcium levels (hypercalcemia) caused by cancer. This medicine works by slowing down the activity of cells that break down bone, helping to strengthen bones and reduce the risk of fractures. Zoledronic acid is given as an intravenous infusion, usually once a year for osteoporosis, or more frequently for cancer-related uses. Key points for patients: The infusion is usually done in a clinic or hospital. You may need blood tests before and after treatment to check your kidney function and calcium levels. Staying well-hydrated and following your doctor's instructions can help reduce the risk of side effects.
