ZOLEDRONIC ACID TEVA 4 MG / 5 ML CONCENTRATE FOR SOLUTION FOR INFUSION - patient leaflet, side effects, dosage

1. what zoledronic acid teva is and what it is used for

The active substance in this medicine 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 zoledronic acid teva

Follow carefully all instructions given to you by your doctor.

Your doctor will carry out blood tests before you start treatment with Zoledronic Acid Teva and will check your response to treatment at regular intervals.

You should not be given Zoledronic Acid Teva

• – 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 before you are given Zoledronic Acid Teva:

• – 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. Your doctor may recommend a dental examination before you start treatment with Zoledronic Acid Teva.

• – if you are having dental treatment or are due to undergo dental surgery, tell your dentist that

you are being treated with Zoledronic Acid Teva and inform your doctor about your dental treatment.

While being treated with Zoledronic Acid Teva, you should maintain good oral hygiene (including regular teeth brushing) and receive routine dental check-ups.

Contact your doctor and dentist immediately if you experience any problems with your mouth or teeth such as loose teeth, pain or swelling, or non-healing of sores or discharge, as these could be signs of a condition called osteonecrosis of the jaw.

Patients who are undergoing chemotherapy and/or radiotherapy, who are taking steroids, who are undergoing dental surgery, who do not receive routine dental care, who have gum disease, who are smokers, or who were previously treated with a bisphosphonate (used to treat or prevent bone disorders) may have a higher risk of developing osteonecrosis of the jaw.

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 Teva. 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 Teva. You will be given adequate calcium and vitamin D supplements.

Patients aged 65 years and over

Zoledronic Acid Teva 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 Teva is not recommended for use in adolescents and children below the age of 18 years.

Other medicines and Zoledronic Acid Teva

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), 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.

• – Other medicines that also contain zoledronic acid and which are 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 Teva 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).

Pregnancy and breast-feeding

You should not be given Zoledronic Acid Teva if you are pregnant. Tell your doctor if you are or think that you may be pregnant.

You must not be given Zoledronic Acid Teva 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 machines or performing other tasks that need full attention.

Important information about some of the ingredients in Zoledronic Acid Teva

This medicine contains less than 1 mmol sodium (23 mg) per vial, that is to say essentially ‘sodium-free’.

• 3. How Zoledronic Acid Teva is given

• – 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, pharmacist or nurse.

How much Zoledronic Acid Teva 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 Teva 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 Teva 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 a single infusion of Zoledronic Acid Teva.

How Zoledronic Acid Teva is given

• – Zoledronic Acid Teva 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 Teva 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 serious side effects straight away:

Common (may affect up to 1 in 10 people):

The following information is intended for healthcare professionals only:

How to prepare and administer Zoledronic Acid Teva

• – To prepare an infusion solution containing 4 mg zoledronic acid, further dilute the Zoledronic

Acid Teva concentrate (5 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 sodium chloride 9 mg/ml (0.9%) solution for injection or 5% w/v glucose solution.

Do not mix Zoledronic Acid Teva concentrate with calcium-containing or other divalent cation containing solutions such as lactated Ringer’s solution.

Instructions for preparing reduced doses of Zoledronic Acid Teva:

Withdraw the appropriate volume of the liquid concentrate, as follows:

• – 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. Please see below for maximum in-use storage time.

• – 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 Teva 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 medicinal products/substances and should always be given through a separate infusion line.

How to store Zoledronic Acid Teva
