1. WHAT ZERLINDA IS AND WHAT IT IS USED FOR
The active substance in Zerlinda 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, e.g. 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 ZERLINDA
Follow carefully all instructions given to you by your doctor.
Your doctor will carry out blood tests before you start treatment with Zerlinda and will check your response to treatment at regular intervals.
You should not be given Zerlinda:
• if you are breast-feeding.
• if you are allergic to zoledronic acid, another bisphosphonate (the group of substances to which Zerlinda belongs), or any of the other ingredients of this medicine (listed in section 6).
Warnings and precautions
Before you are given Zerlinda, tell your doctor:
• 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 Zerlinda.
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.
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.
Other medicines and Zerlinda
Tell your doctor 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 containing zoledronic acid or any other bisphosphonate, since the combined effects of these medicines taken together with Zerlinda are unknown.
• Anti-angiogenic medicines (used to treat cancer), since the combination of these with Zerlinda has been associated with an increased risk of osteonecrosis of the jaw (ONJ).
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.
Zerlinda contains sodium
Each bag with 100ml of solution contains 15.5mmol (356mg) of sodium. To be taken into consideration by patients on a controlled sodium diet.
3. HOW ZERLINDA IS USED
• Zerlinda 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 Zerlinda is given
• The usual single dose given is 4mg.
• If you have a kidney problem, your doctor will give you a lower dose depending on the severity of your kidney problem.
How often Zerlinda is given
• If you are being treated for the prevention of bone complications due to bone metastases, you will be given one infusion of Zerlinda 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 Zerlinda.
The following information is intended for healthcare professionals only:
INFORMATION FOR THE HEALTHCARE PROFESSIONAL How to prepare and administer Zerlinda
• Zerlinda 4mg/100ml solution for infusion contains 4mg zoledronic acid in 100ml of infusion solution for immediate use in patients with normal renal function.
• 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.
• After first opening: Chemical and physical in-use stability has been demonstrated for 24 hours at 2 to 8°C.
From a microbiological point of view, the product 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 to 8°C. The refrigerated solution should then be equilibrated to room temperature prior to administration.
• The solution containing zoledronic acid must not be further diluted or mixed with other infusion solutions. It 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 Zerlinda to assure that they are adequately hydrated.
• Zerlinda 4mg/100ml solution for infusion can be used immediately without further preparation for patients with normal renal function. In patients with mild to moderate renal impairment, reduced doses should be prepared as instructed below.
To prepare reduced doses for patients with baseline CLcr < 60 ml/min, refer to Table 1 below. Remove the volume of Zerlinda solution indicated from the bottle and replace with an equal volume of sterile sodium chloride 9mg/ml (0,9%) solution for injection, or 5% glucose solution for injection.
How Zerlinda is given
• Zerlinda 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 Zerlinda than you should
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 serious 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).
• 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.
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).
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 level of phosphate in the blood.
Common (may affect up to 1 in 10 people):
