Zoledronic acid (for cancer patients)

zoh-leh-dron-ik ass-id

What does it do?

Zoledronic acid is used to treat bone pain caused by cancer, and reduce the amount of calcium in your body.

Before you start

  • Tell your doctor if you have kidney, parathyroid, or dental problems.
  • Zoledronic acid can cause kidney problems. Your doctor will check how your kidneys are working before your infusion.
  • Zoledronic acid may cause problems in your jaw bone. You should be offered a dental check-up before you start to make sure your teeth and gums are healthy. Clean your teeth and visit your dentist regularly. Before you have any dental work, tell your dentist you have had a zoledronic acid infusion.
  • Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

How is it given?

Zoledronic acid is given as an infusion into a vein over 15 to 30 minutes.

Can you take other medicines?

Some medicines available without a prescription may react with zoledronic acid including:

  • anti-inflammatories, such as diclofenac (e.g. Voltaren®), ibuprofen (e.g. Nurofen®), or aspirin (e.g. Disprin®, in doses used for pain relief). These can also be found in some cold and flu medicines (e.g. Nurofen Cold and Flu®).

Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products or recreational drugs.
