Do not let yourself become dehydrated - drink several large glassfuls of water each day.
If you buy any medicines or health remedies, you should ask a pharmacist to advise you. Some mineral preparations and antacid medicines will prevent sodium clodronate from working properly.
Auf einen Blick
Sodium clodronate is a bisphosphonate used for bone pain in cancer and to reduce high blood calcium caused by cancer.
It works by reducing bone breakdown, which strengthens bones and lowers calcium in the blood.
Take doses exactly as prescribed, often on an empty stomach, avoiding food and other medicines for specific times.
Maintain good hydration and dental hygiene while taking this medicine.
Speak to your doctor if you experience thigh, hip, or groin pain, a loose tooth, jaw pain, or ear problems.
About sodium clodronate
Art des Medikaments | Bisphosphonat |
Verwendet für | Bone pain in cancer; and to reduce high blood levels of calcium caused by cancer |
Auch genannt | Clodronate disodium (in US); Clasteon®; Loron 520® |
Verfügbar als | Tablets and capsules |
Sodium clodronate is a bisphosphonate and is prescribed for problems which affect bones. It is prescribed to ease bone pain in people with cancer that has spread into the bone, and also to reduce hypercalcaemia associated with some cancers.
In some cancers 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. This is called hypercalcaemia. Sodium clodronate binds to bone and reduces the rate at which it is broken down. This helps to strengthen bones and prevents the loss of calcium. This in turn reduces the high levels of calcium in the blood.
Before taking sodium clodronate
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 sodium clodronate it is important that your doctor knows:
Wenn Sie schwanger sind oder stillen.
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 in the near future, or if you have nicht recently had a dental check-up.
Wenn Sie Probleme mit der Funktionsweise Ihrer Nieren haben.
Wenn Sie andere Medikamente einnehmen. Dazu gehören alle Medikamente, die Sie einnehmen und die ohne Rezept erhältlich sind, sowie pflanzliche und ergänzende Medikamente.
Wenn Sie jemals eine allergische Reaktion auf ein Medikament hatten.
How to take sodium clodronate
Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about sodium clodronate and will provide you with a full list of the side-effects which you may experience from taking it.
Take sodium clodronate tablets/capsules exactly as your doctor tells you to. It is usual to be prescribed one or two doses to take each day. If you are prescribed one dose to take each day, take it first thing in the morning an hour before you have breakfast. If you are prescribed two doses a day, take your first dose an hour before breakfast and then take your second dose between meals (but see also the following advice).
Some foods and other medicines can interfere with how your body absorbs sodium clodronate and this will prevent the medicine from working as it should. Do not eat anything during the two hours before you take a dose, and also for one hour after taking a dose. It is particularly important that you avoid milk (including any drinks which contain milk) during this three-hour period. If you take other medicines, see the advice in the section below.
Try to take your doses of sodium clodronate at the same times of day each day. This will get you into a good daily routine and will help you avoid missing any doses.
If you do forget to take a dose, just take your next tablet/capsule at the usual time and continue as before. Do not take two doses together to make up for a missed dose.
Das Beste aus Ihrer Behandlung herausholen
Try to keep your regular appointments with your doctor. This is so your doctor can check on your progress. You will need to have regular blood tests during treatment.
It is important that you do not become dehydrated during treatment with sodium clodronate. Your doctor will likely advise you to drink several large glassfuls of water each day. This is especially important in warm weather.
If you are taking any other medicines, do not take them during the two hours before you take sodium clodronate and wait for at least an hour afterwards before you take your other medicines. If you buy any medicines 'over the counter', 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 sodium clodronate which your body absorbs and this will make your treatment less effective. Also, some painkillers called non-steroidal anti-inflammatory drugs (NSAIDs), can cause kidney problems when taken alongside sodium clodronate.
Good dental hygiene is particularly important while you are taking sodium clodronate - brush your teeth regularly and remember to have routine dental check-ups. Also, tell your dentist that you are taking sodium clodronate, as some dental treatments may not be recommended for you.

Durchfall | Drink plenty of water to replace any lost fluids. If this becomes troublesome, speak with your doctor |
Changes to some blood test results | Your doctor will monitor for these |
Less common, but possibly serious side-effects | What should I do if I experience this? |

A loose tooth, or jaw pain with swelling or numbness | Speak with your doctor as soon as possible - these can be signs of a problem called osteonecrosis of the jaw |

Häufig gestellte Fragen
How does sodium clodronate specifically help with bone pain in cancer?
Sodium clodronate works by binding to bone and slowing down the process of bone breakdown. This action helps to strengthen bones that may have been weakened by cancer, which in turn reduces the associated bone pain.
Can I take sodium clodronate if I have an existing dental condition like gum disease?
The article mentions that good dental hygiene is important while taking sodium clodronate and that you should tell your dentist you are taking it because some dental treatments may not be recommended. This suggests that pre-existing dental conditions should be discussed with your doctor and dentist.
What specifically should I avoid eating or drinking when taking sodium clodronate?
You should not eat anything for two hours before taking a dose and for one hour after. It is particularly important to avoid milk, including any drinks containing milk, during this entire three-hour period.
Are there any specific supplements or over-the-counter remedies I should be careful about taking with sodium clodronate?
Yes, mineral supplements, iron preparations, and some indigestion remedies should not be taken during the two hours before sodium clodronate and for at least an hour afterwards, as they can reduce the medicine's effectiveness. You should always check with a pharmacist before taking any over-the-counter medicines.
Why do I need regular blood tests while on sodium clodronate treatment?
Regular blood tests are necessary so your doctor can monitor your progress and check for any changes, including potential changes to some blood test results that can be a side-effect of sodium clodronate.
What should I do if I accidentally take more than the prescribed dose of sodium clodronate?
If you suspect you have taken an overdose, you should go to the accident and emergency department of your local hospital immediately. Remember to take the medicine container with you, even if it's empty.
