Dolutégravir pour le VIH

About dolutegravir

Dolutegravir is an antiretroviral medicine. It is used 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. Dolutegravir is known as an integrase inhibitor antiretroviral medicine. It works by stopping an enzyme which is produced by the virus from working. The virus produces the enzyme to help it multiply in the body, so by preventing it from working, dolutegravir reduces the amount of virus in your body. This helps to maintain the health of your immune system.

Dolutegravir will be prescribed for you by a doctor who is a specialist. 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. It is vital to take them exactly as prescribed to maintain success and to help to prevent the virus from becoming resistant to the medicines. These medicines are usually taken for life.

Before taking dolutegravir

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 dolutegravir it is important that your doctor knows:

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

• Si vous avez des problèmes avec le fonctionnement de votre foie.

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

• 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.
  

How to take dolutegravir tablets

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

• Take dolutegravir exactly as your doctor tells you to. The usual dose is one 50 mg tablet, taken either once or twice a day. The right dose for you will depend upon what other medicines you are taking for HIV.

• If you have been prescribed 5 mg dispersible tablets your daily dose in milligrams will be lower but you will need to take more tablets each day. Follow your doctor's directions closely. Do not take a mixture of normal tablets and dispersible tablets; they do not work in the same way.

• Try to take the tablet at the same time(s) of day each day, as this will help you to remember to take dolutegravir regularly. If you forget to take a dose at your usual time, take it as soon as you remember (unless it is within four hours of your next dose, in which case leave out the missed dose). Do not take two doses together to make up for a forgotten dose.

• Avalez les comprimés entiers avec un verre d'eau.

• If you have been prescribed dispersible (soluble) tablets these can be swallowed whole or dissolved in water first. Follow the manufacturer's instructions closely; the amount of water you need will depend on how many tablets you need for each dose. Do not chew, cut or crush the dispersible tablets. Allow the tablets to dissolve for 1-2 minutes and gently swirl the measuring cup to ensure they are fully dissolved before swallowing.

• Dolutegravir can be taken either with or without food, but if you are known to have resistance to some treatments, your doctor will advise you to always take your doses after a meal as it can increase the effectiveness of the tablets.

Tirer le meilleur parti de votre traitement

• Gardez vos rendez-vous réguliers avec votre médecin afin que vos progrès puissent être suivis. Vous devrez effectuer des analyses de sang régulières.

• It is important that you continue to take dolutegravir 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 the treatment, let your doctor know. As a result of taking dolutegravir, 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.

• Although treatment with antiretroviral medicines can reduce the risk of you passing HIV to others through sexual contact, it does not stop it. It is important that you use condoms.

• Dolutegravir can harm an unborn child so you must avoid getting pregnant while you are taking dolutegravir. Make sure you have discussed with your doctor which types of contraception are suitable for you and your partner. If you are a woman and want to have a family, discuss this with your doctor so that you can be given advice from a specialist about alternative treatment before you become pregnant.

• It is not uncommon for people with HIV to feel low or even depressed, especially soon after the diagnosis has been made and treatment has been started. If you have any feelings of depression you should speak with your doctor 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, supplements or herbal remedies 'over the counter', check with a pharmacist that they are suitable to take with dolutegravir and your other medicines. This is because some medicines interfere with antiretrovirals and can stop them from working properly. Dolutegravir should not be taken with antacid remedies: if you need to take an antacid, you should take it six hours before you take a dose of dolutegravir, or wait until two hours afterwards. Vitamin and mineral supplements must also be taken well separated from dolutegravir.

• 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 dolutegravir regularly, even if you feel well. This is to keep your immune system healthy.
