1. What Zoledronic acid 5 mg is and what it is used for

Zoledronic acid 5 mg contains the active substance zoledronic acid. It belongs to a group of medicines called bisphosphonates and is used to treat:

  • post-menopausal women and adult men with osteoporosis or osteoporosis caused by treatment with corticosteroids used to treat inflammation
  • Paget’s disease of the bone in adults.

Osteoporosis

Osteoporosis is a disease that involves the thinning and weakening of the bones and is common in women after the menopause, but can also occur in men. At the menopause, a woman’s ovaries stop producing the female hormone oestrogen, which helps keep bones healthy. Following the menopause bone loss occurs; bones become weaker and break more easily. Osteoporosis could also occur in men and women because of the long term use of steroids, which can affect the strength of bones. Many patients with osteoporosis have no symptoms but they are still at risk of breaking bones because osteoporosis has made their bones weaker. Decreased circulating levels of sex hormones, mainly oestrogens converted from androgens, also play a role in the more gradual bone loss observed in men. In both women and men, Zoledronic acid 5 mg strengthens the bone and therefore makes it less likely to break. Zoledronic acid 5 mg is also used in patients who have recently broken their hip in a minor trauma such as a fall and therefore are at risk of subsequent bone breaks.

Paget’s disease of the bone

It is normal that old bone is removed and is replaced with new bone material. This process is called remodelling. In Paget’s disease, bone remodelling is too rapid and new bone is formed in a disordered fashion, which makes it weaker than normal. If the disease is not treated, bones may become deformed and painful, and may break. Zoledronic acid 5 mg works by returning the bone remodelling process to normal, securing formation of normal bone, thus restoring strength to the bone.

2. What you need to know before you are given Zoledronic acid 5 mg

Follow all instructions given to you by your doctor, pharmacist or nurse carefully before you are given Zoledronic acid 5 mg.

You must not be given Zoledronic acid 5 mg

  • if you are allergic to zoledronic acid or any of the other ingredients of this medicine (listed in section 6), or to other bisphosphonates
  • if you have hypocalcaemia (this means that the levels of calcium in your blood are too low)
  • if you have severe kidney problems
  • if you are pregnant
  • if you are breast-feeding.

Warnings and precautions

Talk to your doctor, pharmacist or nurse before you are given Zoledronic acid 5 mg:

  • if you are being treated with other products containing the same active substance zoledronic acid as Zoledronic acid 5 mg. Other products containing the active substance zoledronic acid are used in adult patients with certain types of cancer to prevent bone complications or to reduce the amount of calcium)
  • if you have a kidney problem, or used to have one
  • if you are unable to take daily calcium supplements
  • if you have had some or all of the parathyroid glands in your neck surgically removed
  • if you have had sections of your intestine removed.

A side effect called osteonecrosis of the jaw (ONJ) (bone damage in the jaw) has been reported in the post-marketing setting in patients receiving zoledronic acid for osteoporosis. ONJ can also occur after stopping treatment.

It is important to try and prevent ONJ developing as it is a painful condition that can be difficult to treat. In order to reduce the risk of developing osteonecrosis of the jaw, there are some precautions you should take.

Before receiving Zoledronic acid 5 mg treatment, tell your doctor, pharmacist or nurse if

  • you have any problems with your mouth or teeth such as poor dental health, gum disease, or a planned tooth extraction
  • you do not receive routine dental care or have not had a dental check-up for a long time
  • you are a smoker (as this may increase the risk of dental problems)
  • you have previously been treated with a bisphosphonate (used to treat or prevent bone disorders)
  • you are taking medicines called corticosteroids (such as prednisolone or dexamethasone)
  • you have cancer.

Your doctor may ask you to undergo a dental examination before you start treatment with Zoledronic acid 5 mg.

While being treated with Zoledronic acid 5 mg, you should maintain good oral hygiene (including regular teeth brushing) and receive routine dental check-ups. If you wear dentures you should make sure these fit properly. If you are under dental treatment or are due to undergo dental surgery (e.g. tooth extractions), inform your doctor about you dental treatment and tell your dentist you are being treated with Zoledronic acid 5 mg. 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 osteonecrosis of the jaw.

Monitoring test

Your doctor should do a blood test to check your kidney function (levels of creatinine) before each dose of Zoledronic acid 5 mg. It is important for you to drink at least 2 glasses of fluid (such as water), within a few hours before receiving Zoledronic acid 5 mg, as directed by your healthcare provider.

Children and adolescents

Zoledronic acid 5 mg is not recommended for anyone under 18 years of age.

Other medicines and Zoledronic acid 5 mg

Pregnancy and breast-feeding

You must not be given Zoledronic acid 5 mg if you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby.

Ask your doctor, pharmacist or nurse for advice before taking this medicine.

3. How Zoledronic acid 5 mg is used

Follow carefully all instructions given to you by your doctor or nurse. Check with your doctor or nurse if you are not sure.

Osteoporosis

The usual dose is 5 mg given as one infusion per year into a vein by your doctor or nurse. The infusion will take at least 15 minutes.

In case you recently broke your hip, it is recommended that Zoledronic acid 5 mg is administered two or more weeks after your hip repair surgery.

It is important to take calcium and vitamin D supplements (for example tablets) as directed by your doctor.

For osteoporosis, Zoledronic acid 5 mg works for one year. Your doctor will let you know when to return for your next dose.

Paget’s disease

For the treatment of Paget’s disease, Zoledronic acid 5 mg should be prescribed only by physicians with experience in the treatment of Paget’s disease of the bone.

The usual dose is 5 mg, given to you as one initial infusion into a vein by your doctor or nurse. The infusion will take at least 15 minutes. Zoledronic acid 5 mg may work for longer than one year, and your doctor will let you know if you need to be treated again.

Your doctor may advise you to take calcium and vitamin D supplements (e.g. tablets) for at least the first ten days after being given Zoledronic acid 5 mg. It is important that you follow this advice carefully so that the level of calcium in your blood does not become too low in the period after the infusion. Your doctor will inform you regarding the symptoms associated with hypocalcaemia.

Zoledronic acid 5 mg with food and drink

Make sure you drink enough fluids (at least one or two glasses) before and after the treatment with Zoledronic acid 5 mg, as directed by your doctor. This will help to prevent dehydration.

If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.
