Maraviroc tablets for HIV

About maraviroc

Maraviroc is an antiretroviral medicine. It is used for human immunodeficiency virus (HIV) infection. 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. Maraviroc is known as a CCR5 antagonist antiretroviral medicine. It works by blocking a receptor, called CCR5, which HIV uses to enter your CD4 T cells. By reducing the amount of virus getting into your cells, it helps to maintain the health of your immune system.

Maraviroc 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.

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 maraviroc it is important that your doctor knows:

• Si está embarazada o en periodo de lactancia.

• Si tiene algún problema con el funcionamiento de su hígado, o si tiene algún problema con el funcionamiento de sus riñones.

• Si tiene algún problema con el corazón o los vasos sanguíneos.

• Si está tomando otros medicamentos. Esto incluye todos los medicamentos que se pueden comprar sin receta, así como las hierbas medicinales y los medicamentos complementarios.

• If you have ever had an allergic reaction to a medicine, or if you are allergic to peanuts or soya.

• It is important that you continue to take maraviroc 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 maraviroc, 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.

• Follow carefully any advice your doctor gives to you about making some lifestyle changes to reduce any risk of damage to your heart and blood vessels. These can include stopping smoking, eating healthily and taking regular exercise.

• Aunque el tratamiento con antirretrovíricos puede reducir el riesgo de transmitir el VIH a otras personas a través del contacto sexual, no lo detiene. Es importante que utilices preservativos.

• 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 straightaway.

• Algunas personas que han tomado antirretrovirales (sobre todo durante mucho tiempo) han desarrollado una enfermedad llamada osteonecrosis. Se trata de una enfermedad ósea en la que el tejido óseo muere debido a la reducción del riego sanguíneo. Produce dolores y rigidez en las articulaciones y puede dificultar el movimiento. Si notas alguno de estos síntomas, habla con tu médico.

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

• Si va a someterse a una operación o a un tratamiento dental, comunique siempre a la persona que lleve a cabo el tratamiento qué medicamentos está tomando.

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