About sodium clodronate

Type of medicine Bisphosphonate
Used for Hypercalcaemia (too much calcium in the blood)
Some types of bone pain
Also called Bonefos®
Clasteon®
Loron 520®
Available as Tablets and capsules

In cancer there can be an excessive breakdown of bone. As this happens, calcium is lost from the bone and seeps into the blood leading to higher than normal levels of calcium in the blood. Sodium clodronate works by binding to bone and reducing the rate at which it is broken down. This helps prevent the loss of calcium from bones and reduces the high levels of calcium in the blood.

Before taking sodium clodronate

Before taking sodium clodronate make sure your doctor or pharmacist knows:

  • If you are pregnant, trying for a baby or breast-feeding.
  • If you suffer from kidney problems.
  • If you have recently had any inflammation of your digestive system such as an upset stomach or bowel.
  • If you are due to have any dental treatment (as your doctor may advise that your dental treatment is completed before starting this medicine).
  • If you are taking other medicines, including those available to buy without a prescription, herbal and complementary medicines.
  • If you have ever had an allergic reaction to this or any other medicine.

How to take sodium clodronate

  • Before starting this treatment, read the manufacturer's printed information leaflet from inside the pack.
  • Take sodium clodronate exactly as your doctor has told you. It is usually taken once or twice a day.
  • Do not eat any food during the hour before your dose is due and for one hour after you have taken sodium clodronate. You should also avoid milk (including any drinks containing milk), iron supplements, mineral supplements and indigestion remedies during this two hour period. This is because these prevent the sodium clodronate from working as it should.
  • Try to take sodium clodronate at the same times each day to avoid missing any doses.
  • If you do forget to take a dose, don't worry, just take the next dose when it is due. Do not take two doses together to make up for a forgotten dose.

Getting the most from your treatment

  • Drink plenty of water while you are taking sodium clodronate. You should drink several large glassfuls of water each day.
  • If you are having any dental treatment, tell your dentist that you are taking sodium clodronate as some dental treatments are not recommended.
  • Keep your regular appointments with your doctor so your progress can be monitored. You will need to have your calcium blood levels checked regularly and also have other tests from time to time.
  • If you take or buy any 'over the counter' medicines, check with a pharmacist that they are safe to take with sodium clodronate. Some painkillers, such as non-steroidal anti-inflammatory drugs (NSAIDs), should not be taken alongside sodium clodronate.
