What this medicine is used for

The name of your medicine is APO-Zoledronic Acid 4mg/5mL or APO-Zoledronic Acid 4mg/100mL. It contains the active ingredient zoledronic acid (as monohydrate).
It is used to:
lower the amount of calcium in the blood when it becomes too high, as may happen in some forms of cancer.
Some cancers can speed up normal changes in bone so that the amount of calcium released from the bones into the blood is increased.
It is also used to:
slow down the spread of cancers in bone, helping to prevent changes to the bones that may cause them to weaken.
It is used in people with advanced cancer of the bone marrow (called multiple myeloma) and other advanced cancers that have spread to the bone. This medicine is used in addition to other standard cancer treatments.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.
This medicine is available only with a doctor's prescription.

How it works

Zoledronic acid belongs to a group of medicines called bisphosphonates, which strongly bind to bone. These medicines slow down the rate of bone change and help to restore the amount of calcium in the blood to normal.
There is no evidence that this medicine is addictive.

Use in children

This medicine should not be used in children. The safety and effectiveness in children have not been established.

pain in the teeth, gums or jaw, swelling or numbness of the jaw or a 'heavy jaw feeling' or loosening of a tooth.

4. You are currently receiving or are planning to receive dental treatment.

It is advisable to have a dental check-up before starting zoledronic acid. Tell your dentist you may be receiving zoledronic acid.

Some medicines may interact with zoledronic acid. These include:
medicines that may affect your kidneys, such as fluid tablets
aminoglycoside medicines, used to treat severe infections. The combination of aminoglycoside and bisphosphonate medicines may cause the level of calcium in the blood to become too low anti-angiogenic medicines as part of your cancer treatment. The combination of these medicines and bisphosphonate medicines may increase the risk of bone damage in the jaw (osteonecrosis)
any other medicine containing zoledronic acid, or other bisphosphonates such as risedronate, alendronate
thalidomide, a medicine used in clinical trials to treat multiple myeloma
loop diuretics, medicines used to treat high blood pressure or oedema.
