Ibandronic acid

Each time you collect a prescription, make sure you have been given the same brand of tablet as before. This is because there are different brands of ibandronic acid tablets and not all are used for the same condition.

If you buy any medicines, make sure your pharmacist knows that you are taking these tablets, as some medicines will prevent ibandronic acid from working properly.

Good dental hygiene is particularly important with this treatment - this means that you must brush your teeth regularly, and have routine dental check-ups.

About ibandronic acid

Type of medicine Bisphosphonate
Used for Osteoporosis; to prevent bone damage in people with breast cancer that has spread to the bone; or to reduce high levels of calcium in the blood caused by cancer (injection only)
Also called Bonviva®; Bondronat®; Iasibon®; Quodixor®
Available as Tablets and injection

You will be prescribed ibandronic acid to prevent bone damage (in conditions such as osteoporosis or if you have a secondary bone cancer), or to reduce a high blood level of calcium resulting from a cancer that has spread to your bone.

When ibandronic acid is used to treat osteoporosis (Bonviva® brand), it is only suitable for women who have been through the menopause. Osteoporosis is a bone disease which causes your bones to become brittle and fragile, making them prone to breaks and fractures. During our lifetime, old bone tissue is constantly being broken down and replaced by new bone. After the age of about 35 years, our bone begins to lose density because old bone is lost faster than new bone can replace it. Women in particular have an increased risk of developing osteoporosis because they lose bone material rapidly after the menopause. Ibandronic acid slows down the rate at which old bone is lost. New bone continues to be made and this leads to an overall increase in bone density, which reduces your risk of broken bones and fractures.

Ibandronic acid (Bondronat® brand) is used to help treat complications associated with cancer. In some cancers there can be an excessive breakdown of bone. As this happens, the bone is weakened and calcium is lost from the bone and seeps into the blood, leading to higher-than-normal blood levels of calcium. Ibandronic acid helps by binding to bone, making the bone stronger and reducing the amount of calcium leaving the bone.

Before taking ibandronic acid

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking these tablets it is important that your doctor or pharmacist knows:

  • If you are pregnant or breast-feeding.
  • If you have ever had any difficulties swallowing.
  • If you are due to have any dental treatment in the near future, or if you have not recently had a dental check-up.
  • If you have kidney or heart problems.
  • If you are unable to sit upright for at least 60 minutes.
  • If you have been told you have low amounts of calcium in your blood.
  • If you are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, such as herbal and complementary medicines.
  • If you have ever had an allergic reaction to a medicine.

How to take ibandronic acid

  • Before you start this treatment, read the manufacturer's printed information leaflet from inside your pack. The leaflet will give you more information about the specific brand of tablets you have been given, and a full list of side-effects which you may experience from taking them. Not all brands of tablet are used to treat each of the conditions mentioned in this leaflet.
  • If you are taking Bonviva® tablets: the usual dose is one 150 mg tablet, once a month. You must take your dose on the same day of each month, so choose a day that best suits your routine. If you forget to take a dose, take it on the morning after you remember. However, if when you remember, your next dose is due within seven days, then you should not take the missed tablet, just take your next dose when it is due.
  • If you are taking Bondronat® tablets: the usual dose is one 50 mg tablet each morning, although you may be asked to take it less frequently than this if you have any problems with the way your kidneys work. If on any day you forget to take a dose, just take your tablet on the next day as usual. Do not take a double dose to make up for a missed dose

Taking ibandronic acid tablets:

It is important that you take each tablet of ibandronic acid in the correct way, as otherwise they can cause irritation and damage as they are swallowed.

  • Take the tablet first thing in the morning, before you eat any food or have anything to drink other than water. You should also make sure it is more than six hours since you last ate food on the previous day.
  • Swallow the tablet whole - you must not chew, break, or crush the tablet. You must drink a large glassful of water as you take the tablet, and it is important that you take the tablet while you are standing or sitting in an upright position.
  • Continue to sit or stand upright for 60 minutes after taking a tablet - you must not lie down during this time.
  • Do not have anything to eat or drink (other than water) for at least 30 minutes after taking a tablet. If you are taking Bonviva® tablets, you must not eat or drink anything (other than water) for 60 minutes afterwards. This is because food stops the tablet from working and makes your treatment much less effective.

Getting the most from your treatment

  • Try to keep your regular appointments with your doctor. This is so your doctor can check on your progress. It is likely you will need to have regular blood tests during this treatment.
  • Good dental hygiene is particularly important while you are taking these tablets - brush your teeth regularly and remember to have routine dental check-ups. Tell your dentist that you are taking ibandronic acid, as some dental treatments may not be recommended for you while you are taking these tablets.
  • If you buy any medicines, check with a pharmacist that they are suitable for you to take. This is because mineral supplements, iron preparations, and some indigestion remedies reduce the amount of ibandronic acid which your body absorbs. This may make your treatment less effective.
  • Eating a well-balanced diet and taking regular exercise can help your bones stay strong. Remember to follow any exercise or dietary advice your doctor gives to you.
  • Chemicals from tobacco can get into your bloodstream and can affect your bones, making bone loss worse. If you smoke, you should try to make every effort to stop. Ask your doctor or pharmacist for advice on stopping.
