About zoledronic acid

Zoledronic acid is used in the treatment of a number of different problems which affect bones.

In some cancers there can be an excessive breakdown of bone. As this happens, calcium is lost from the bone and seeps into the blood leading to higher than normal levels of calcium in the blood. Zoledronic acid works by binding to bone and reducing the rate at which it is broken down. This helps strengthen bones by preventing the loss of calcium and also reduces the high levels of calcium in the blood.

In Paget's disease, zoledronic acid works on bones to make them stronger and help prevent bone thickening. This helps ease symptoms such as pain, bone deformity and fracture.

In osteoporosis, zoledronic acid helps by preventing further loss of bone and by helping to rebuild lost bone. By doing this, it reduces the risk of spine and hip fractures.

Before having zoledronic acid

Before having zoledronic acid make sure your doctor or pharmacist knows:

• If you have liver, kidney or heart problems.
• If you are due to have any dental treatment (as your doctor may advise that your dental treatment is completed before starting zoledronic acid).
• If you are a woman and have not yet been through the menopause.
• If you are taking other medicines, including those available to buy without a prescription, herbal and complementary medicines.
• If you have ever had an allergic reaction to this or any other medicine.

How to take zoledronic acid

• Zoledronic acid will be given to you by intravenous infusion in a hospital.
• The number of doses you require will depend upon the reason you are being treated with zoledronic acid.

Getting the most from your treatment

• It is important that you do not become dehydrated during treatment with zoledronic acid. Your doctor will probably advise you drink a couple of glassfuls of water before and after your treatment.
• It may be necessary for you to take tablets of calcium and vitamin D as a supplement alongside this treatment. If so, your doctor will prescribe this for you.
• Good dental hygiene is important - this means that you must brush your teeth regularly and have regular dental check-ups.
• Tell your dentist that you are having zoledronic acid as some dental treatments will not be recommended for you.
• Remember to follow any lifestyle advice your doctor has given you. Eating a well-balanced diet, stopping smoking and taking regular exercise can help bones stay strong.
• Keep your regular appointments with your doctor so your progress can be monitored.
