About sodium clodronate
Type de médicament | Bisphosphonate |
Utilisé pour | Bone pain in cancer; and to reduce high blood levels of calcium caused by cancer |
Également appelé | Clodronate disodium (in US); Clasteon®; Loron 520® |
Disponible en | 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:
Si vous êtes enceinte ou si vous allaitez.
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 not recently had a dental check-up.
Si vous avez des problèmes de fonctionnement des reins.
Si vous prenez d'autres médicaments. Cela inclut tous les médicaments que vous prenez et qui sont disponibles sans ordonnance, ainsi que les médicaments à base de plantes et les médicaments complémentaires.
Si vous avez déjà eu une réaction allergique à un médicament.

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.
Tirer le meilleur parti de votre traitement
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.
