Q: What is Zometa?
A: Zometa (zoledronic acid) is used to treat hypercalcemia (excess calcium in the blood) that may occur with some types of cancer. It is also used to treat multiple myeloma (tumors formed by the cells of the bone marrow), as well as to treat bone metastasis (spread of cancer).
Zometa is an intravenous bisphosphonate drug made by Novartis Pharmaceuticals Corporation and was approved by the U.S. Food and Drug Administration (FDA) in 2001 for treating hypercalcemia, and in 2002 for treatment of bone metastasis.
Q: Has there been any recent news about Zometa?
A: In September 2004, Novartis Pharmaceuticals and the FDA notified dental healthcare professionals of revisions to prescribing information to describe the occurrence of osteonecrosis of the jaw (ONJ) observed in cancer patients receiving treatment with intravenous bisphosphonates (such as Zometa). The revised prescribing information recommends that cancer patients receive a dental examination prior to starting bisphosphonate treatment, and that they avoid invasive dental procedures while on these medications.
Q: What is Osteonecrosis of the Jaw?
A: Osteonecrosis of the Jaw (ONJ), or 'jaw death,' is a medical condition in which the jawbone partially crumbles and dies. ONJ may cause severe pain, loose teeth, exposed bone, loss of function, and disfigurement.
Q: Are there any special instructions for taking Zometa?
