1. WHAT ZoLEDRoNIc AciD is AND WHAT iT is
used for
The active substance in Zoledronic acid is zoledronic acid, which belongs to a group of substances called bisphosphonates. Zoledronic acid works by attaching itself to the bone and slowing down the rate of bone change. It is used:
• To prevent bone complications eg. fractures, in adult patients with bone metastases (spread of cancer from primary site to the bone)
• To reduce the amount of calcium in the blood in adult patients where it is too high due to the presence of a tumour. Tumours can accelerate normal bone change in such a way that the release of calcium from bone is increased. This condition is known as tumour-induced hypercalcaemia (TIH).
2. WHAT YOU NEED TO Know BEFORE YOU ARE
given zoledronic acid
Follow carefully all instructions given to you by your doctor.
Your doctor will carry out blood tests before you start treatment with Zoledronic acid and will check your response to treatment at regular intervals.
You should not be given Zoledronic acid:
• if you are breast-feeding.
• if you are allergic to zoledronic acid, another bisphosphonate (the group of substances to which Zoledronic acid belongs), or any of the other ingredients of this medicine (listed in section 6)
Warnings and precautions
• Talk to your doctor, pharmacist or nurse before you are given Zoledronic acid:
- if you have or have had a kidney problem.
- if you have or have had pain, swelling or numbness of the jaw, a feeling of heaviness in the jaw or loosening of a tooth.
- if you are having dental treatment or are due to undergo dental surgery, tell your dentist that you are being treated with Zoledronic acid.
Reduced levels of calcium in the blood (hypocalcaemia), sometimes leading to muscle cramps, dry skin, burning sensation, have been reported in patients treated with Zoledronic acid. Irregular heart beat (cardiac arrhythmia), seizures, spasm and twitching (tetany) have been reported as secondary to severe hypocalcaemia. In some instances the hypocalcaemia may be life-threatening. If any of these apply to you, tell your doctor straight away.
Other medicines and Zoledronic acid
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
It is especially important that you tell your doctor if you are also taking:
• Aminoglycosides (medicines used to treat severe infections), since the combination of these with bisphosphonates may cause the calcium level in the blood to become too low.
• Thalidomide (a medicine used to treat a certain type of blood cancer involving the bone) or any other medicines which may harm your kidneys.
• Other medicines that also contain zoledronic acid, or any other bisphosphonate, since the combined effects of these medicines taken together with Zoledronic acid are unknown.
• Anti-angiogenic medicines (used to treat cancer), since the combination of these with zoledronic acid has been associated with reports of osteonecrosis of the jaw (ONJ).
Patients aged 65 years and over
Zoledronic acid can be given to people aged 65 years and over. There is no evidence to suggest that any extra precautions are needed.
children and adolescents
Zoledronic acid is not recommended for use in adolescents and children below the age of 18 years.
Pregnancy and breast-feeding
You should not be given Zoledronic acid if you are pregnant. Tell your doctor if you are pregnant, think that you may be pregnant or planning to have a baby.
You must not be given Zoledronic acid if you are breast-feeding.
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking any medicine.
Driving and using machines
There have been very rare cases of drowsiness and sleepiness with the use of Zoledronic acid. You should therefore be careful when driving, using machinery or performing other tasks that need full attention.
Zoledronic acid contains less than 1 mmol sodium (23 mg)
per vial (5 ml), i.e. essentially "sodium-free".
3. how zoledronic acid is used
• Zoledronic acid must only be given by healthcare professionals trained in administering bisphosphonates intravenously, i.e. through a vein.
• Your doctor will recommend that you drink enough water before each treatment to help prevent dehydration.
• Carefully follow all the other instructions given to you by your doctor, nurse or pharmacist.
How much Zoledronic acid is given
• The usual single dose given is 4 mg.
• If you have a kidney problem, your doctor will give you a lower dose depending on the severity of your kidney problem.
How often Zoledronic acid is given
• If you are being treated for the prevention of bone complications due to bone metastases, you will be given one infusion of Zoledronic acid every three to four weeks.
• If you are being treated to reduce the amount of calcium in your blood, you will normally only be given one infusion of Zoledronic acid
How Zoledronic acid is given
• Zoledronic acid is given as a drip (infusion) into a vein which should take at least 15 minutes and should be administered as a single intravenous solution in a separate infusion line.
Patients whose blood calcium levels are not too high will also be prescribed calcium and vitamin D supplements to be taken each day.
if you are given more Zoledronic acid than you should be
If you have received doses higher than those recommended, you must be carefully monitored by your doctor. This is because you may develop serum electrolyte abnormalities (e.g. abnormal levels of calcium, phosphorus and magnesium) and/or changes in kidney function, including severe kidney impairment. If your level of calcium falls too low, you may have to be given supplemental calcium by infusion.
4. possible side effects
Like all medicines, this medicine can cause side effects,
although not everybody gets them. The most common ones are
usually mild and will probably disappear after a short time.
Tell your doctor about any of the following side effects
straight away:
common (may affect up to 1 in 10 people):
• Severe kidney impairment (will normally be determined by your doctor with certain specific blood tests).

Uncommon (may affect up to 1 in 100 people):
• Pain in the mouth, teeth and/or jaw, swelling or sores inside the mouth, numbness or a feeling of heaviness in the jaw, or loosening of a tooth. These could be signs of bone damage in the jaw (osteonecrosis). Tell your doctor and dentist immediately if you experience such symptoms.
• Irregular heart rhythm (atrial fibrillation) has been seen in patients receiving zoledronic acid for postmenopausal osteoporosis. It is currently unclear whether zoledronic acid causes this irregular heart rhythm but you should report it to your doctor if you experience such symptoms after you have received zoledronic acid.
• Severe allergic reaction: shortness of breath, swelling mainly of the face and throat.
Very rare (may affect up to 1 in 10,000 people):
• As a consequence of low calcium values: irregular heart beat (cardiac arrhythmia; secondary to hypocalcaemia), seizures, numbness and tetany (secondary to hypocalcaemia).

information for the healthcare professional
The following information is intended for healthcare professionals only:
How to prepare and administer Zoledronic acid
• To prepare an infusion solution containing 4 mg zoledronic acid, further dilute the zoledronic acid concentrate (5.0 ml) with 100 ml of calcium-free or other divalent cation-free infusion solution. If a lower dose of zoledronic acid is required, first withdraw the appropriate volume as indicated below and then dilute it further with 100 ml of infusion solution. To avoid potential incompatibilities, the infusion solution used for dilution must be either 9 mg/ml sodium chloride or 50 mg/ml glucose solution.
Do not mix Zoledronic acid concentrate with calcium containing or other divalent cation-containing solutions such as lactated Ringer’s solution.
Instructions for preparing reduced doses of Zoledronic acid: Withdraw the appropriate volume of the liquid concentrate, as follows:
• 4.4 ml for 3.5 mg dose
• 4.1 ml for 3.3 mg dose
• 3.8 ml for 3.0 mg dose
• For single use only. Any unused solution should be discarded. Only clear solution free from particles and discolouration should be used. Aseptic techniques must be followed during the preparation of the infusion.
• From a microbiological point of view, the diluted solution for infusion should be used immediately. If not used immediately, in-use storage times and conditions prior to use are the responsibility of the user and would normally not be longer than 24 hours at 2°C - 8°C. The refrigerated solution should be equilibrated to room temperature prior to administration.
• The solution containing zoledronic acid is given as a single 15-minute intravenous infusion in a separate infusion line. The hydration status of patients must be assessed prior to and following administration of Zoledronic acid to ensure that they are adequately hydrated.
• Studies with several types of infusion lines made from polyvinylchloride, polyethylene and polypropylene showed no incompatibility with zoledronic acid.
• Since no data are available on the compatibility of zoledronic acid with other intravenously administered substances, zoledronic acid must not be mixed with other medications/ substances and should always be given through a separate infusion line.
How to store Zoledronic acid
• Keep zoledronic acid out of the sight and reach of children.
• Do not use zoledronic acid after the expiry date stated on the pack.
• This medicinal product does not require any special storage conditions.
The diluted zoledronic acid infusion solution should be used immediately in order to avoid microbial contamination.
