Darunavir pour le VIH

About darunavir

Darunavir is an antiretroviral medicine. It is prescribed for infection par le virus de l'immunodéficience humaine (VIH). It slows the progress of HIV infection, but it is not a cure. HIV destroys cells in the body, called CD4 T cells. These cells are a type of white blood cell and are important because they are involved in protecting your body from infection. If left untreated, the HIV infection weakens your immune system so that your body cannot defend itself against bacteria, viruses and other germs. Darunavir slows down the progress of HIV infection by reducing the amount of virus in your body. It does this by stopping the production of a protein that the virus needs to copy (replicate) itself.

Darunavir will be prescribed for you by a doctor who is a specialist. It belongs to a group of antiretroviral medicines known as protease inhibitors (PIs). It is given alongside a number of other antiretroviral medicines, as part of a combination therapy. Taking three or more antiretroviral medicines at the same time is more effective than taking one alone. Taking a combination of different medicines also reduces the risk that the virus will become resistant to any individual medicine. One brand of darunavir called Rezolsta® also contains a medicine called cobicistat. Cobicistat boosts the effect of darunavir. Not all of the information in this document may apply to the combination brand - please refer to the manufacturer's printed information leaflet from inside the pack.

Il est essentiel de prendre vos médicaments antirétroviraux exactement comme prescrit pour maintenir le succès et aider à empêcher le virus de devenir résistant aux médicaments. Ces médicaments sont généralement pris à vie.

Before taking darunavir

Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking darunavir it is important that your doctor knows:

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

• Si vous avez le diabète (diabète sucré).

• Si vous avez une inflammation du foie (appelée hépatite), ou tout autre problème hépatique.

• Si vous souffrez d'hémophilie ou de porphyrie, qui sont toutes deux des maladies sanguines héréditaires rares.

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

• If you have ever had an allergic reaction to a medicine. This is particularly important if you know you are allergic to a medicine known as a sulfonamide.

How to take darunavir

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about darunavir, and it will also provide you with a full list of the side-effects which you could experience from taking it.

• Take darunavir exactly as your doctor tells you to. You will be asked to take either one or two doses daily, at the same time as a booster medicine (either ritonavir or cobicistat).

• There are several strengths of darunavir tablets available - your doctor will tell you which is right for you (or your child). It is important that you take darunavir at a mealtime (or within 30 minutes of eating a meal) as this will help your body to absorb the medicine.

• Try to take darunavir at the same time(s) of day each day, as this will help you to remember to take it regularly.

• If you forget to take your dose, take it with something to eat as soon as you remember sauf si:
  

  • You usually take darunavir twice a day and you are more than 6 hours late; in which case do not take the missed dose but do take your next dose when it is due.

  • You usually take darunavir once a day and you are more than 12 hours late; in which case do not take the missed dose but do take your next dose when it is due.

Instructions for using the dosing syringe with Prezista® Oral Suspension

1. Shake the bottle well.

2. Remove the bottle cap.

3. Make sure the plunger of the syringe is pushed in fully, then insert the syringe into the bottle.

4. Gently pull out the plunger of the syringe so that the medicine fills the syringe to the mark which corresponds to your dose.

5. Put the tip of the syringe into your (or your child's) mouth, and gently push the plunger so that the medicine is released.

6. Remplacez le bouchon de la bouteille. Lavez la seringue à l'eau après chaque utilisation.

Tirer le meilleur parti de votre traitement

• Keep your regular appointments with your doctor so that your progress can be monitored. You will need to have regular blood tests while you are taking this medicine, to make sure your liver stays healthy.

• It is important that you continue to take darunavir and your other antiretroviral treatment regularly. This will help to prevent the HIV from becoming resistant to the medicines you are taking. Even if you miss only a small number of doses, the virus can become resistant to treatment.

• If you develop any infection soon after you start this treatment, let your doctor know. As a result of taking darunavir, your immune system may start fighting an infection which was present before you started the treatment, but which you may not have been aware of.

• Suivez attentivement tous les conseils que votre médecin vous donne concernant les changements de mode de vie pour réduire tout risque de dommage à votre cœur et à vos vaisseaux sanguins. Cela peut inclure l'arrêt du tabac, une alimentation saine et la pratique régulière d'exercice physique.

• Certaines personnes prenant des médicaments antirétroviraux développent des modifications de la répartition de la graisse corporelle dans le corps. Cela peut entraîner des changements dans l'image corporelle. Votre médecin discutera de cette possibilité avec vous.

• Bien que le traitement avec des médicaments antirétroviraux puisse réduire le risque de transmission du VIH à d'autres par contact sexuel, il ne l'élimine pas. Il est important d'utiliser des préservatifs.

• Being pregnant whilst taking darunavir can lead to lower blood levels of the medicine. This may mean your treatment becomes less effective than it should be. If you are pregnant, or planning to become pregnant, speak with your doctor for advice on alternative treatments.

• Il n'est pas rare que les personnes vivant avec le VIH se sentent déprimées ou même dépressives, surtout peu de temps après le diagnostic et le début du traitement. Si vous ressentez des symptômes de dépression ou avez des pensées inquiétantes concernant l'automutilation, vous devriez en parler à votre médecin immédiatement.

• Certaines personnes qui ont pris des médicaments antirétroviraux (en particulier sur une longue période) ont développé une affection appelée ostéonécrose. Il s'agit d'une maladie osseuse où le tissu osseux meurt en raison d'une réduction de l'apport sanguin. Cela entraîne des douleurs articulaires et une raideur, et peut causer des difficultés de mouvement. Si vous remarquez l'un de ces symptômes, parlez-en à votre médecin.

• If you buy any medicines, check with a pharmacist that they are suitable to take with darunavir and your other medicines. This is because some medicines interfere with darunavir and either stop it from working properly or increase the risk of side-effects. In particular, do not take the herbal remedy St John's wort.

• Si vous êtes diabétique, vous devrez peut-être vérifier votre glycémie (glucose) plus fréquemment, car ce médicament peut affecter les niveaux de sucre dans votre sang. Votre médecin vous conseillera à ce sujet.

• Si vous subissez une opération ou un traitement dentaire, informez la personne qui effectue le traitement des médicaments que vous prenez.

• Treatment for HIV is usually lifelong. Continue to take darunavir regularly for as long as your doctor tells you to, even if you feel well. This is to keep your immune system healthy.

Can darunavir 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 darunavir. 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: although it is common for people taking darunavir to develop a skin rash during the first few weeks of treatment, a severe rash with blisters may be a sign of a more serious allergic-type reaction. Let your doctor know immédiatement if you develop the following:

• Severe blistering rash, high temperature, muscle and joint aches or pains, feeling generally unwell, mouth ulcers, and conjunctivitis.

Si vous ressentez d'autres symptômes que vous pensez être dus au médicament, parlez-en à votre médecin ou à votre pharmacien pour obtenir des conseils supplémentaires.
