Cobicistat tablets for HIV

About cobicistat

Cobicistat is prescribed for human immunodeficiency virus (HIV) infection. 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. You will be prescribed three or more antiretroviral medicines at the same time, as taking a combination of different medicines is more effective than taking one alone, and also it reduces the risk that the HIV virus will become resistant to any individual medicine. Antiretroviral medicines slow the progress of HIV infection, but do not cure it.

Cobicistat will be prescribed for you by a doctor who is a specialist. You will also have been prescribed either atazanavir or darunavir for the HIV infection. Cobicistat is given to boost the effect of these medicines. Atazanavir and darunavir are both protease inhibitor antiretroviral medicines. Cobicistat helps to improve the effectiveness of these medicines by slowing down their breakdown in the body. This increases the amount of time atazanavir or darunavir is present in your body.

Some brands of cobicistat contain other antiretroviral medicines also (see the list in the table above). Taking one of these brands helps to reduce the number of tablets you need to take each day. Not all of the information in this leaflet applies to the combination brands - please refer to the manufacturer's printed information leaflet from inside the pack for full details about these brands. You will also find more information about each of the individual medicines on our website (see atazanavir, darunavir, emtricitabine, tenofovir).

Before taking cobicistat

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 cobicistat it is important that your doctor knows:

• Wenn Sie schwanger sind, ein Kind erwarten oder stillen.

• Wenn Sie Probleme mit der Funktionsweise Ihrer Leber haben oder wenn Sie Probleme mit der Funktionsweise Ihrer Nieren haben.

• Wenn Sie schon einmal eine allergische Reaktion auf ein Arzneimittel hatten.

• Wenn Sie andere Arzneimittel einnehmen. Dazu gehören alle Arzneimittel, die ohne Rezept erhältlich sind, sowie pflanzliche und ergänzende Arzneimittel.

How to take cobicistat tablets

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

• Take cobicistat exactly as your doctor tells you to. Take one tablet a day, at the same time as either atazanavir or darunavir.

• Swallow the tablet whole with a drink of water. Take the tablet after a meal or a snack.

• If you forget to take a dose, take it as soon as you remember, providing it is within 12 hours of the time you should have taken it. Remember to take the tablet with something to eat. However, if when you remember, it is more than 12 hours late, do not take the dose you missed but instead take your next dose when it is due. Do not take two doses together to make up for the forgotten dose.

Das Beste aus Ihrer Behandlung herausholen

• Keep your regular appointments with your doctor so that your progress can be monitored. You are likely to need regular blood tests to check how well your medicines are working.

• It is important that you continue to take your 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 an infection soon after you start the treatment, let your doctor know. As a result of taking antiretroviral medicines, 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.

• Die Behandlung mit antiretroviralen Medikamenten kann zwar das Risiko einer HIV-Übertragung durch sexuelle Kontakte verringern, aber nicht verhindern. Es ist wichtig, dass Sie Kondome benutzen.

• If you are trying for a baby or you become pregnant whilst taking cobicistat, let your doctor know straightaway. Your doctor may recommend a different treatment combination that could be more effective during pregnancy.

• Es ist nicht ungewöhnlich, dass sich Menschen mit HIV niedergeschlagen oder sogar depressiv fühlen, vor allem kurz nachdem die Diagnose gestellt und die Behandlung begonnen wurde. Wenn Sie sich deprimiert fühlen oder beunruhigende Gedanken haben, sich selbst zu schaden, sollten Sie sofort mit Ihrem Arzt sprechen.

• If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking cobicistat and antiretroviral medicines.

• If you buy any medicines, supplements or herbal remedies 'over the counter', check with a pharmacist that they are suitable to take with cobicistat and your other medicines. This is because cobicistat can interfere with some medicines and stop them from working properly.
