What Ostira™ is used for

Ostira™ contains the active ingredient zoledronic acid. It belongs to a group of medicines called bisphosphonates.

Ostira™ is used

  • to treat osteoporosis in postmenopausal women to reduce incidence of bone fractures.
  • To strengthen bones in men who have osteoporosis
  • to treat osteoporosis in men and women over 50 years of age, to prevent additional fractures in those who have had a hip fracture,
  • to treat or prevent osteoporosis in men and women caused by treatment with steroid medicines such as prednisone
  • to treat Paget's disease of bone.

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 in which 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.

.Your doctor may have prescribed Ostira™ for another purpose.

Ask your doctor if you have any questions regarding why Ostira™ has been prescribed for you.

Ostira™ is not addictive.

This medicine is available only with a doctor’s prescription.

It is advisable to have a dental check-up before starting on Ostira™. Tell your dentist you may be receiving Ostira™.

Tell your doctor if you need to have any dental treatment or dental surgery. A dental condition called jaw osteonecrosis has been reported in some patients being treated with zoledronic acid or with other drugs in the same class as Ostira™. You may need to have dental treatments completed before starting it.

If you have not told your doctor about any of the above, tell them before you start receiving Ostira™.

Your doctor may want to take special precautions if you have any of the above conditions.

Taking other medicines

Tell your doctor if you are taking any other medicines, including any that you have bought without a prescription from a pharmacy, supermarket or healthfood shop. Also tell your doctor if you are being treated with other medicines which may contain zoledronic acid.

Some medicines may interfere with Ostira™. These medicines include:

  • medicines that may have side effects on your kidneys (e.g. Diuretics or ‘water’ tablets)
  • aminoglycoside medicines, used to treat severe infections. The combination of an aminoglycoside and bisphosphonate medicine may cause the level of calcium in the blood to become too low.

These medicines may be affected by Ostira™, or may affect how well it works. You may need to receive different amounts of your medicine, or you may need to take different medicines. Your doctor will advise you.

Your doctor or pharmacist has more information on medicines to be careful with or avoid while receiving Ostira™.

Ask your doctor or pharmacist if you are not sure about this list of medicines.

How Ostira™ is given

Ostira™ is administered by a healthcare professional in a hospital setting. It is given as a ‘drip’ into a vein, usually over a period of 15 minutes. It is given once per year.

Make sure you drink enough fluids before and after the treatment 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.

Ostira™ is given as a single infusion over a period of at least 15 minutes. Each dose lasts at least one year. Your doctor will decide if you need additional doses.

Your doctor may also prescribe a daily calcium supplement and a multiple vitamin containing Vitamin D.

If you receive too much

As Ostira™ is given to you under the supervision of your doctor, it is very unlikely that you will receive too much.

Tell your doctor if you have any of the following symptoms. This may mean that the level of calcium in your blood is too low

  • unusual light headedness, dizziness or faintness
  • numbness or tingling
  • muscle cramps

Your doctor may give you extra calcium supplements, should your calcium level become too low.

While you are having Ostira™

Things you must do

Make sure you follow your doctor's instructions carefully and keep all appointments.

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

Take calcium and vitamin D supplements if your doctor has told you to. Most people with osteoporosis do not get enough calci
um and vitamin D in their diet and supplements are needed to help strengthen your bones.

If you are being treated with Ostira™ 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 Ostira™ to reduce the risk of low calcium levels in your blood.

Tell all doctors, dentists and pharmacists who are treating you that you are receiving Ostira™.

Tell your doctor if you become pregnant while receiving Ostira™.

Practice good dental hygeine. Be sure to brush and floss your teeth daily, and have regular dental check-ups.

If you develop pain in your mouth, teeth or jaw, or have bleeding gums, or have an unusual feeling in your teeth or gums, tell your doctor and dentist immediately. A dental condition called jaw osteonecrosis has been reported in some patients being treated with zoledronic acid or other drugs in the same class.
