Disodium pamidronate

Disodium pamidronate is a type of bisphosphonate. You might have it as part of your treatment for a number of different types of cancer.

How disodium pamidronate works

Disodium pamidronate is a treatment for cancers that break down bone cells or have spread to the bones. It sticks to the bone and helps to reduce bone loss.

It also lowers high levels of calcium in the blood (hypercalcaemia), which can happen in secondary bone cancer. Secondary bone cancer is when a cancer has spread to the bones from where it started.

How you have disodium pamidronate

You have disodium pamidronate as a drip into your bloodstream (intravenously).

You have treatment through a long plastic tube that goes into a large vein in your chest. The tube stays in place throughout the course of treatment. This can be a:

  • central line
  • PICC line
  • portacath

If you don't have a central line

You might have treatment through a thin short tube (a cannula) that goes into a vein in your arm. You have a new cannula each time you have treatment.

When you have disodium pamidronate

You can have disodium pamidronate as a one off treatment to reduce calcium levels in your blood. Or you can have it every 3 to 4 weeks as a regular treatment to prevent or reduce bone damage.

Each treatment lasts from one to several hours depending on the dose.


You have blood tests before starting treatment and during your treatment. They check your blood calcium levels. You might also need to do urine samples for testing and have tests to check how well your heart and kidneys are working.

Side effects

How often and how severe the side effects are can vary from person to person. They also depend on what other treatment you are having. 

When to contact your team

Your doctor, nurse, or pharmacist will go through the possible side effects. They will monitor you closely during treatment and check how you are at your appointments. Contact your advice line as soon as possible if:

  • you have severe side effects 
  • your side effects aren’t getting any better
  • your side effects are getting worse
Early treatment can help manage side effects better.

We haven't listed all the side effects here. Remember it is very unlikely that you will have all of these side effects, but you might have some of them at the same time.

Common side effects

These side effects happen in more than 10 in 100 people (more than 10%). You might have one or more of them. They include:

Flu like symptoms

For about 24 to 48 hours after treatment, you might have flu like symptoms including a high temperature (fever), chills and a headache. 

Low levels of calcium and phosphate in the blood

Low calcium levels in the blood can cause painful muscle spasms, cramps or muscle twitching. You might also get numbness or tingling in your feet, hands or around your mouth.

Tell your doctor or nurse if you experience these side effects.

Low levels of phosphate can cause muscle weakness and confusion.

You have blood tests to check the levels of calcium and phosphate, as well as other substances such as potassium and magnesium.
