1. What Bondronat is and what it is used for

Bondronat contains the active substance ibandronic acid. This belongs to a group of medicines called bisphosphonates.

Bondronat is used in adults and prescribed to you if you have breast cancer that has spread to your bones (called ‘bone metastases’).

  • It helps to prevent your bones from breaking (fractures)
  • It also helps to prevent other bone problems that may need surgery or radiotherapy

Bondronat works by reducing the amount of calcium that is lost from your bones. This helps to stop your bones from getting weaker.

2. What you need to know before you take Bondronat

Do not take Bondronat:

  • if you are allergic to ibandronic acid or any of the other ingredients of this medicine that are listed in section 6
  • if you have problems with your food pipe/gullet (oesophagus) such as narrowing or difficulty swallowing
  • if you cannot stand or sit upright for at least one hour (60 minutes) at a time
  • if you have or ever had low calcium in your blood

Do not take this medicine if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking Bondronat.

Warnings and precautions

A side effect called osteonecrosis of the jaw (ONJ) (bone damage in the jaw) has been reported very rarely in the post marketing setting in patients receiving Bondronat for cancer-related conditions. 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 treatment, tell your doctor/nurse (health care professional) if:

  • you have any problems with your mouth or teeth such as poor dental health, gum disease, or a planned tooth extraction
  • you don’t 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 starting treatment with Bondronat.

While being treated, 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 will undergo dental surgery (e.g. tooth extractions), inform your doctor about your dental treatment and tell your dentist that you are being treated with Bondronat.

Contact your doctor and dentist immediately if you experience any problems with your mouth or teeth such as loose teeth, pain or swelling, non-healing of sores or discharge, as these could be signs of osteonecrosis of the jaw.

Talk to your doctor or pharmacist before taking Bondronat:

  • if you are allergic to any other bisphosphonates
  • if you have any swallowing or digestion problems
  • if you have high or low blood levels of vitamin D or any other minerals
  • if you have kidney problems

Irritation, inflammation or ulceration of the gullet/food pipe (oesophagus) often with symptoms of severe pain in the chest, severe pain after swallowing food and/or drink, severe nausea, or vomiting may occur, especially if you do not drink a full glass of water and/or if you lie down within an hour of taking Bondronat. If you develop these symptoms, stop taking Bondronat and tell your doctor straight away (see sections 3 and 4).

Children and adolescents

Bondronat should not be used in children and adolescents below the age of 18 years.

Other medicines and Bondronat

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This is because Bondronat can affect the way some other medicines work. Also some other medicines can affect the way Bondronat works.

In particular, tell your doctor or pharmacist if you are taking any of the following medicines:

  • supplements containing calcium, magnesium, iron or aluminium
  • acetylsalicylic acid and non-steroidal anti-inflammatory medicines called “NSAIDs”, such as ibuprofen or naproxen. This is because NSAIDs, and Bondronat can both irritate your stomach and gut
  • a type of antibiotic injection called “aminoglycoside” such as gentamicin. This is because aminoglycosides and Bondronat can both lower the amount of calcium in your blood

Taking medicines that reduce stomach acid such as cimetidine and ranitidine, may slightly increase the effects of Bondronat.

Bondronat with food and drink

Do not take Bondronat with food or any other drinks except water as Bondronat is less effective if it is taken with food or drink (see section 3).

Take Bondronat at least 6 hours after you last had anything to eat, drink or any other medicines or supplements (e.g. products containing calcium (milk), aluminium, magnesium and iron) except water. After taking your tablet, wait at least 30 minutes. Then you can have your first food and drink, and take any medicines or supplements (see section 3).

Pregnancy and breast feeding

Do not take Bondronat if you are pregnant, planning to get pregnant or if you are breast-feeding.

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

Driving and using machines

You can drive and use machines as it’s expected that Bondronat has no or negligible effect on your ability to drive and use machines. Talk to your doctor first if you want to drive, use machine or tools.

Bondronat contains lactose

If you have been told by your doctor that you cannot tolerate or digest some sugars (e.g. if you have a galactose intolerance, the Lapp lactase deficiency or have problems with glucose-galactose absorption), talk to your doctor before taking this medicine.

3. How to take Bondronat

Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

Take your tablet at least 6 hours after you last had anything to eat, drink or any other medicines or supplements except water. Water with a high concentration of calcium should not be used. If there is concern regarding potentially high levels of calcium in the tap water (hard water), it is advised to use bottled water with a low mineral content.

Your doctor may do regular blood tests while you are taking Bondronat. This is to check that you are being given the right amount of medicine.

Taking this medicine

It is important that you take Bondronat at the right time and in the right way. This is because it can cause irritation, inflammation or ulcers in your food pipe/gullet (oesophagus).

You can help stop this happening by doing the following:

  • Take your tablet as soon as you get up for the day before having your first food, drink, any medicine or supplements
  • Take your tablet with a full glass of water only (about 200 mL). Do not take your tablet with any drink other than water
  • Swallow the tablet whole. Do not chew, suck or crush the tablet. Do not let the tablet dissolve in your mouth
  • After taking your tablet, wait at least 30 minutes. Then you can have your first food and drink, and take any medicines or supplements
  • Stay upright (sitting or standing) while taking your tablet and for the next hour (60 minutes). Otherwise, some of the medicine could leak back into your food pipe/gullet (oesophagus)

How much to take

The usual dose of Bondronat is one tablet each day. If you have moderate kidney problems, your doctor may reduce your dose to one tablet every other day. If you have severe kidney problems, your doctor may reduce your dose to one tablet each week.

If you take more Bondronat than you should

If you take too many tablets talk to a doctor or go to hospital straight away. Drink a full glass of milk before you go. Do not make yourself sick. Do not lie down.

If you forget to take Bondronat

Do not take a double dose to make up for a forgotten dose. If you are taking a tablet each day, skip the missed dose completely. Then carry on as usual the next day. If you are taking a tablet every other day or once a week, ask your doctor or pharmacist for advice.

If you stop taking Bondronat

Keep taking Bondronat for as long as your doctor tells you. This is because the medicine will only work if it is taken all the time.

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