What this medicine is used for

The name of your medicine is Zoledasta™. It contains the active ingredient zoledronic acid.

It is used to treat:

  • treat osteoporosis in postmenopausal women to reduce the incidence of fractures
  • treat osteoporosis in men and women over 50 years of age to reduce the incidence of additional fractures in patients who have had a hip fracture
  • increase bone mineral density in men with osteoporosis
  • increase bone mineral density in men and women with osteoporosis associated with long term steroid use, such as prednisone
  • prevent bone mineral density loss caused by steroid use in men and women
  • treat Paget's disease of bone in men and women.

Osteoporosis is a disease which causes bones to become less dense, gradually making them weaker, more brittle and likely to break. This is common in women after menopause, when a woman's ovaries stop producing the female hormone, oestrogen, which keeps bones healthy. It also occurs in men and women with increasing age. Broken bones may result from injury or simple falls. Breaks may occur during normal everyday activity, such as lifting, or from minor injury that would not ordinarily fracture normal bone. Fractures in people with osteoporosis usually occur at the hip, spine or wrist. These can lead not only to pain, but also to considerable deformity and disability, such as stooped posture from curvature of the spine, and loss of mobility.

Paget's disease is a chronic disorder which may affect various bones of the skeleton. Bone is a living tissue and, just like other parts of the body, it is constantly being renewed. This process is called bone remodelling. In Paget's disease, the bone material breaks down more quickly than usual and new bone material grows more quickly than usual and in a disordered way. The new bone that is formed may be thicker but weaker than normal, which can cause pain and may lead to fractures (broken bones).

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

Zoledasta™ works by slowing down bone resorption, which allows the bone-forming cells time to rebuild normal bone. This allows bone remodelling to go back to normal and protects the bones from being weakened.

There is no evidence that this medicine is addictive.

Use in children

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

Taking other medicines

Some medicines may interact with Zoledasta™ .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.

If you are taking any of these you may need a different dose or you may need to take different medicines.

Other medicines not listed above may also interact with zoledronic acid.

How this medicine is given

Zoledasta™ is given as a no less than 20 minute infusion into a vein by your doctor or nurse once a year. You may also be given an infusion of fluids to ensure that you do not become dehydrated.

How much will you be given

Your doctor will tell you how much of this medicine you will be given. This will depend on your condition and whether you are taking any other medicines.

For osteoporosis, each dose of Zoledasta™ lasts one year. Your doctor will check your condition and may prescribe further annual doses.

For Paget's disease, treatment is a single infusion of Zoledasta™. In some cases re-treatment may be necessary. Your doctor will let you know if you need to be treated again.

Make sure you drink enough fluids before and after the treatment with this medicine as directed by your doctor. Two glasses of fluid (such as water) before and after the infusion are usually enough. This will help to prevent dehydration.

If you take too much (overdose)

If you think that you or anyone else may have taken too much of this medicine, immediately telephone your doctor or the Poisons Information Centre (Tel: 13 11 26 in Australia) for advice. Alternatively, go to the Accident and Emergency department at your nearest hospital.

Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

Symptoms of an overdose may include:

  • muscle spasms
  • numbness or tingling sensation, especially around the mouth
  • shortness of breath.

These symptoms may mean the level of calcium in your blood has fallen too far.

While you are taking this medicine

Things you must do

Tell your doctor that you are taking this medicine if:

  • you have any dental symptoms including pain or unusual feeling in your teeth of gums, or any dental infections
  • you are about to be started on any new medicine
  • you plan to have any vaccinations or immunisations
  • you are pregnant or are planning to become pregnant
  • you are breastfeeding or are planning to breastfeed
  • you are about to have any blood tests
  • you are going to have surgery or an anaesthetic or are going into hospital.

Your doctor may occasionally do tests such as X-rays, bone density scans or blood tests to make sure the medicine is working and to prevent side effects.

Go to your doctor regularly for a check-up.

Tell any other doctors, dentists and pharmacists who are treating you that you take this medicine.

Take calcium and vitamin D supplements if your doctor has told you to.

  • Most people with osteoporosis do not get enough calcium and vitamin D in their diet and supplements are needed to help strengthen your bones.
  • If you are being treated with Zoledasta™ for Paget's disease, your doctor should advise corrective treatment for a vitamin D deficiency and that you take calcium and vitamin D supplements for at least the first ten days after you have Zoledasta™ . This is to reduce the risk of low calcium levels in your blood.

Things to be careful of

Be careful when driving or operating machinery until you know how this medicine affects you. If you are travelling home by car after the infusion, arrange to have someone else drive.

Practice good dental hygiene. Your routine dental hygiene should include:

  • brushing your teeth and tongue after every meal and at bedtime
  • gentle flossing once a day to remove plaque
  • avoiding use of mouthwash that contains alcohol.

Keep your mouth moist by drinking water. 'Dry mouth' can lead to decay and other dental problems.

Use a mirror to check your teeth and gums regularly for any changes such as sores or bleeding gums. If you notice any problems, tell your doctor and dentist immediately.
