A propos du calcitriol
Type de médicament | A type of vitamin D |
Utilisé pour | To promote healthy bones |
Également appelé | Rocaltrol® |
Disponible en | Capsules |
You will have been prescribed calcitriol because you have either a bone disease called renal osteodystrophy or because you have postmenopausal 'thinning' of the bones (osteoporosis). In both these conditions, calcitriol will help your body to absorb the minerals it needs and this will help to strengthen your bones.
Calcitriol is a type of vitamin D. Vitamin D helps to regulate the amount of two minerals in your body, called calcium and phosphate. All three of these substances are important for maintaining healthy, strong bones and teeth.
There are several types of vitamin D available but most other types need 'activating' by the kidneys. Calcitriol is a form of vitamin D which does not need this activation process, and so it is particularly helpful for people who need their bones strengthening but who also have kidney problems. You may also need to take mineral supplements along with calcitriol.
Before taking calcitriol
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 calcitriol it is important that your doctor knows:
Si vous êtes enceinte ou si vous allaitez.
If you know you have too much calcium in your blood or urine. This can happen with some cancers.
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 calcitriol
Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about calcitriol and will provide you with a full list of the side-effects which you may experience from taking it.
Take calcitriol exactly as your doctor tells you to. If you have renal osteodystrophy, it is likely that you will be prescribed one dose a day, although some people may only need to take a dose on alternate days. When you first start the treatment, your doctor may give you a small dose and then gradually increase it. This allows your doctor to make sure that you have the dose that helps your condition but avoids any unwanted symptoms.
For 'thinning' of the bones (osteoporosis), the usual dose is one 250 nanogram capsule, twice daily.
Try to take your doses at the same times of day each day, as this will help you to remember to take calcitriol regularly. Swallow the capsules with a drink of water.
If you forget to take a dose at your usual time, take it when you remember. Try to take the correct number of doses each day, but 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. Your doctor will want you to have regular blood tests to check on the amount of calcium in your blood and also on how well your kidneys are working.
Your doctor or dietician will discuss with you how to maintain a well-balanced and healthy diet. Please follow any advice you are given about what to eat and drink. It is important that you have plenty to drink so that you don't become dehydrated and that you don't eat foods that have been fortified with vitamin D.
Treatment with calcitriol is often long-term. Continue to take the capsules regularly unless you are told otherwise by your doctor.
