What this medicine is used for

Zoledasta™ 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.

Paget’s disease is a chronic disorder which may affect various bones of the skeleton. Bone is a living tissue and is constantly being renewed. 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 broken bones.

How it works

Zoledasta™ works by slowing down the breaking down of bone, 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.

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.

This medicine is not addictive.

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

Before you start to use it

Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes.

Tell your doctor if you have been treated with or are being treated with:

  • other medicines which contain zoledronic acid
  • other bisphosphonate medicines
  • diuretic therapy (commonly called ‘fluid tablets’).

  • you are unable to take daily calcium or vitamin D supplements

  • you have had sections of your intestine removed

  • uveitis or iritis (inflammatory conditions of the eye).

Tell your doctor if you are planning to have surgery, dental treatment or an anaesthetic.

It is advisable to have a dental check-up before starting your medicine. Tell your dentist you may be receiving Zoledasta™. A dental condition called jaw osteonecrosis has been reported in some patients being treated with Zoledasta™ or other drugs in the same class as your medicine. You may need to have dental treatment completed before starting it.

If you have not told your doctor about any of the above, tell them before you start taking this medicine.

Taking other medicines

Tell your doctor if you are taking any other medicines, including any that you get from your pharmacy, supermarket or health food shop.

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.

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, depending on your condition and if you are taking any other medicines.

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

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)

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice or go to the Emergency department at your nearest hospital if you think that you or anyone else may have taken too much of this medicine. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

Overdose symptoms 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

If you get a headache, fever or other flu-like symptoms in the first three days after you are given Zoledasta™, take paracetamol if your doctor has told you to. Some people get short-lasting flu-like symptoms after having Zoledasta™.Paracetamol can provide some relief.

If you are about to be started on any new medicine, tell your doctor and pharmacist that you are taking this medicine.

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

Tell your doctor and dentist if you have any dental symptoms including pain or an unusual feeling in your teeth or gums, loosening of a tooth and/or non-healing sores, discharge (pus or oozing), or any other dental infections. A dental condition called jaw osteonecrosis has been reported, primarily in patients being treated with this type of medicine for other illnesses.

Tell your doctor if you are pregnant, plan to become pregnant or are breastfeeding.

Tell your doctor if you are going to have surgery or an anaesthetic or are going into hospital.

Go to your doctor regularly for a check-up. 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.

Your doctor may ask you to take calcium and vitamin D supplements. 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. Zoledasta™ may cause dizziness in some people and affect the ability to drive or operate machinery. 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.
