Hydromorphone pour la douleur cancéreuse

About hydromorphone

Opioïdes puissants are medicines used to treat severe pain. Hydromorphone is a type of strong opioid (sometimes called an opiate) used to treat pain caused by le cancer. It works on your nervous system and brain to reduce the amount of pain you feel.

Hydromorphone is taken by mouth as a capsule. There are two types of capsule available: quick-acting capsules (Palladone®) and modified-release capsules (Palladone® SR). Modified-release capsules release the hydromorphone they contain more slowly than the quick-acting capsules do. This provides longer and more even pain relief.

Before taking hydromorphone

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 hydromorphone it is important that your doctor knows:

• Si vous êtes enceinte, essayez d'avoir un bébé ou allaitez.

• Si vous avez des problèmes de foie ou de reins.

• Si vous avez des problèmes de prostate ou des difficultés à uriner.

• Si vous avez des problèmes respiratoires, tels que l'asthme ou la maladie pulmonaire obstructive chronique (MPOC).

• If you have been told you have low blood pressure (hypotension).

• If you have any problems with your thyroid, pancreas, or adrenal glands.

• Si vous avez de l'épilepsie.

• Si vous avez un problème avec votre canal biliaire.

• Si vous êtes constipé depuis plus d'une semaine ou si vous avez un problème inflammatoire de l'intestin.

• Si vous avez une affection provoquant une faiblesse musculaire, appelée myasthénie grave.

• If you have a mental health problem called toxic psychosis.

• Si vous avez récemment subi une blessure grave à la tête.

• Si vous avez déjà été dépendant aux drogues ou à l'alcool.

• Si vous avez déjà eu une réaction allergique à un médicament.

• Si vous prenez d'autres médicaments. Cela inclut tous les médicaments que vous prenez et qui sont disponibles à l'achat sans ordonnance, ainsi que les médicaments à base de plantes et les médecines complémentaires.

How to take hydromorphone

• Before you start taking the capsules, read the manufacturer's printed information leaflet from inside the pack. The manufacturer's leaflet will give you more information about hydromorphone and a full list of the side-effects which you may experience from taking it.

• Take hydromorphone exactly as your doctor tells you to. If you have been prescribed the quick-acting capsules (Palladone®), you will be asked to take a dose every four hours. The modified-release capsules (Palladone® SR) are taken twice a day, 12 hours apart.

• There are different strengths of both types of hydromorphone capsule, so each time you collect a prescription check to make sure it is the strength you are expecting.

• You can swallow the capsules whole with a drink of water, or alternatively, open them and sprinkle the contents on to some soft food, such as yoghurt. Do not dissolve or chew the contents of the capsule as this may release all the medicine at once and cause side-effects.

• You can take hydromorphone before or after food.

• If you forget to take a dose, take it as soon as you remember and then continue as before. If it is nearly time for your next dose, leave out the forgotten dose and take the next dose when it is due. Do not take two doses together to make up for a forgotten dose. If you are taking quick-acting capsules do not take more than one dose every four hours.

Tirer le meilleur parti de votre traitement

• Ask your doctor for advice before drinking alcohol while you are on this medicine. Your doctor may recommend you do not drink alcohol while you are on hydromorphone because it increases the possibility of side-effects such as feeling dizzy and sleepy.

• If you are a driver, please be aware that hydromorphone is likely to affect your reactions and ability to drive. It is an offence to drive while your reactions are impaired. Even if your driving ability is not impaired, should you drive, you are advised to carry with you some evidence that the medicine has been prescribed for you - a repeat prescription form or a patient information leaflet from the pack is generally considered suitable.

• If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking hydromorphone as a painkiller.

• If you buy any medicines, check with a pharmacist that they are suitable for you to take with hydromorphone. Many other medicines have similar side-effects to hydromorphone, and taking them together will increase the risk of these.

• If you are planning a trip abroad, you are advised to carry a letter with you from your doctor to explain that you have been prescribed hydromorphone. This is because hydromorphone is classed as a 'controlled drug' and is subject to certain restrictions.

• Continue to take hydromorphone unless your doctor tells you otherwise. Stopping suddenly will cause your pain to return, and it can also cause you to feel agitated, anxious, and sweaty. If you need to stop taking hydromorphone your doctor will prescribe an alternative painkiller for you, or reduce your dose gradually.

Can hydromorphone cause problems?

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with hydromorphone. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

Important: people taking opioid medicines, and their family and friends, should be aware of the risk of accidental overdose and know when to seek medical help. The risk is higher if you also take other medicines that make you feel drowsy. Signs you have taken too much medicine include:

• Se sentir très somnolent ou étourdi.

• Se sentir mal (nausée) ou vomir (vomissements).

• Difficultés respiratoires.

• Perte de connaissance.

If you have taken more morphine than you should or someone else accidentally swallows your medication, call for an ambulance and tell them the name of your medicine.

Si vous ressentez d'autres symptômes que vous pensez être dus à ce médicament, parlez-en à votre médecin ou à votre pharmacien.
