1. WHAT ZOLEDRONIC ACID IS AND WHAT IT IS USED FOR
The active substance zoledronic acid 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, e.g. fractures, in adult patients with bone metastases (this is when the cancer has spread from the primary cancer 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. 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 (hypersensitive) to zoledronic acid, another bisphosphonate (the group of substances to which Zoledronic acid belongs), or any of the other ingredients of Zoledronic acid (listed in section 6).
Warnings and precautions
Talk to your doctor 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 (you should also 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. If you have pre-existing hypocalcaemia, it must be corrected before initiating the first dose of Zoledronic acid. You will be given adequate calcium and vitamin D supplements.
Using other medicines
Please tell your doctor if you are taking or have recently taken any other medicines, including medicines obtained without a prescription. It is especially important that you tell your doctor if you are also taking:
• Aminoglycosides (medicines used to treat severe infections), calcitonin (a type of medicine used to treat post-menopausal osteoporosis and hypercalcaemia), loop diuretics (a type of medicine to treat high blood pressure or oedema) or other calcium-lowering medicines, 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.
• Aclasta (a medicine that also contains zoledronic acid and is used to treat osteoporosis and other non- cancer diseases of the bone), 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 an increased risk 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.
Use in 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 or think that you may be pregnant. You must not be given Zoledronic acid if you are breast-feeding. Ask your doctor for advice before taking any medicine while you are pregnant or breast-feeding. 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.
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 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.
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 you will be given Zoledronic acid
• 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.
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 will be carefully monitored by your doctor. This is because you may develop abnormal levels of calcium, phosphorus and magnesium in your blood and/or changes in kidney function, including severe kidney problems.
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, Zoledronic acid can cause side effects, although not everybody gets them. The most common side effects are usually mild and will probably disappear after a short time. Tell your doctor straight away if you get any of the following serious side effects:
Common (may affect up to 1 in 10 people):
- Severe kidney impairment (will normally be determined by your doctor with certain specific blood tests).
- Low level of calcium in the blood.
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.
Rare (may affect up to 1 in 1,000 people):
- As a consequence of low calcium values: irregular heart beat (cardiac arrhythmia; secondary to hypocalcemia).
Very rare (may affect up to 1 in 10,000 people):
- As a consequence of low calcium values: seizures, numbness and tetany (secondary to hypocalcaemia).
Tell your doctor about any of the following side effects as soon as possible:
Very common (may affect more than 1 in 10 people):
• Low levels of phosphate in the blood.
Common (may affect up to 1 in 10 people):
• Headache and a flu-like syndrome consisting of fever, fatigue, weakness, drowsiness, chills and bone, joint and/or muscle ache. In most cases no specific treatment is required and the symptoms disappear after a short time (couple of hours or days).
• Gastrointestinal reactions such as nausea and vomiting as well as loss of appetite.
• Conjunctivitis.
• Low levels of red blood cells (anaemia).
Uncommon (may affect up to 1 in 100 people):

INFORMATION FOR THE HEALTHCARE PROFESSIONAL
How to prepare and administer Zoledronic acid 4 mg/5 ml concentrate for solution for infusion
• To prepare an infusion solution containing 4 mg Zoledronic acid, 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 0.9% w/v sodium chloride or 5% w/v 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 then 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.
• 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 reach and sight of children.
• Do not use Zoledronic acid after the expiry date stated on the pack.
• The unopened vial does not require any specific storage conditions.
• The diluted Zoledronic acid infusion solution should be used immediately in order to avoid microbial contamination.
