Bisphosphonates

Bisphosphonates are drugs that in certain situations can help to protect your bones against some of the effects of cancer, such as pain and weakness.

What are bisphosphonates?

Bisphosphonates are drugs that strengthen bones and reduce the risk of bones breaking (fracture). They can also be used to treat a high level of calcium in the blood (hypercalcaemia). They may also help relieve bone pain.

You may have bisphosphonate therapy:

There are different types of bisphosphonates. The 1 you have will depend on your general health and the type of cancer you have.

Types of bisphosphonates

Zoledronic acid

Zoledronic acid is a type of bisphosphate that is given by a drip (infusion). It can be used to:

  • help protect the bones from the effects of some treatments for early breast cancer
  • reduce the risk of early breast cancer coming back – this is called adjuvant treatment
  • reduce a raised calcium level in the blood caused by cancer that has spread to the bones (secondary bone cancer)
  • treat bone weakness or pain caused by myeloma or by breast cancer that has spread to the bones.

Pamidronate

Pamidronate is a type of bisphosphate that is given by a drip (infusion). It can be used to treat:

  • high levels of calcium in the blood caused by cancer that has spread to the bones
  • bone weakness or pain caused by myeloma or by breast cancer that has spread to the bones.

Clodronate

Clodronate is a type of bisphosphate that you take as capsules or tablets. It can be used to treat:

  • high levels of calcium in the blood caused by cancer that has spread to the bones
  • bone weakness or pain caused by myeloma or breast cancer that has spread to the bones.

Ibandronic acid

Ibandronic acid is a type of bisphosphate that is given by drip (infusion) or as a tablet. It can be used to treat:

  • high levels of calcium in the blood caused by cancer that has spread to the bones
  • bone weakness or pain caused by breast cancer that has spread to the bones.

Bisphosphonates side effects

Some common side effects of bisphosphonates include:

  • flu-like symptoms, such as pains in the muscles and joints, which usually settle after the first dose
  • low levels of calcium in the blood – your doctor may advise you to take calcium and vitamin D supplements to prevent this
  • shortness of breath
  • diarrhoea
  • indigestion or a sore throat – usually more common in people who are taking oral bisphosphonates

Your doctor can give you drugs to help control some side effects. It is important to take the drugs exactly as your specialist or pharmacist explains. This means they will be more likely to work for you. Your nurse will give you advice about managing your side effects. After your treatment is over, most side effects start to improve.

Jaw problems (osteonecrosis)

Rarely, these treatments can affect the jawbone. Healthy bone in the jaw becomes damaged and dies. This is called osteonecrosis of the jaw (ONJ). It can cause:

  • pain
  • loosening of the teeth
  • problems with the way the gums heal.

The risk of jaw problems is higher:

  • after some types of dental treatment
  • in people who have gum disease
  • if dentures do not fit well.

It is important to avoid having any dental treatment that could affect your jawbone when you are having bisphosphonates. This includes having a tooth or root removed, or dental implants put in. You can still have fillings, gum treatments, or a scale and polish. Your healthcare team can tell you more.
