Lopinavir med ritonavir för HIV

About lopinavir with ritonavir

Kaletra® contains two ingredients - lopinavir and ritonavir. These are both antiretroviral medicines prescribed for human immunodeficiency virus (HIV) infection. Lopinavir is the main active ingredient and ritonavir helps to boost the amount of lopinavir which gets into your bloodstream. Kaletra® 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. Kaletra® 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.

Lopinavir and ritonavir belong to a group of antiretroviral medicines known as protease inhibitors (PIs). They are 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.

Antiretroviral medicines will be prescribed for you by a doctor who is a specialist. It is vital to take your antiretroviral medicines exactly as prescribed in order 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 lopinavir with ritonavir

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 lopinavir with ritonavir it is important that your doctor knows:

• Om du är gravid, försöker bli gravid eller ammar.

• If you have diabetes (diabetes mellitus).

• If you have a heart problem or have been told you have a heart rhythm disorder.

• If you have liver inflammation (called hepatitis), or any other liver problem.

• Om du har problem med hur dina njurar fungerar.

• If you have inflammation of the pancreas (pancreatitis).

• If you are being treated for low levels of thyroid hormone (hypothyroidism).

• If you have either haemophilia or porphyria, which are both rare inherited blood disorders.

• Om du tar några andra läkemedel. Detta inkluderar alla läkemedel som kan köpas utan recept, samt växtbaserade och komplementära läkemedel.

• Om du någonsin har haft en allergisk reaktion mot en medicin.

How to take lopinavir with ritonavir

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

• Take Kaletra® exactly as your doctor tells you to - the directions will be printed on the label of the pack to remind you about what the doctor said to you. The usual dose for an adult is two tablets taken twice a day (12 hours apart), although some people can be asked to take four tablets once daily. If you have any difficulties swallowing tablets, let your doctor know about this as the liquid medicine could be more suitable for you.

• Depending upon their age, children can be prescribed tablets or liquid medicine. The dose will depend upon their weight and height. If you (or your child) have been given liquid medicine to take, your doctor will advise you about how much you should take for each dose, and how to measure it out correctly using the dosing syringe provided in the pack. Wash the syringe with water after each use.

• Tablets should be swallowed with a drink of water. Do not crush or break the tablet before you swallow - it should be swallowed whole. You can take Kaletra® tablets either with or without food.

• If you are taking liquid medicine, you should always take your doses with a meal. This is because food in your stomach helps the liquid medicine to be absorbed better by your body.

• Try to take your doses at the same times of day each day, as this will help you to remember to take the tablets/medicine regularly.

• If you forget to take a dose, take it as soon as you remember unless:
  

  • You usually take your doses 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 your doses 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.

• Keep your regular appointments with your doctor so that your progress can be monitored. You will need to have regular blood tests.

• It is important that you continue to take 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 this medicine, 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 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.

• Some people taking antiretroviral medicines develop changes to the way body fat is distributed in the body. This can result in changes to body image. Your doctor will discuss the possibility of this with you.

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

• 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, or any distressing thoughts about harming yourself then you should speak with your doctor omedelbart.

• Some people who have taken antiretroviral medicines (particularly over a long time) have developed a condition called osteonecrosis. This is a bone disease where bone tissue dies because there is a reduced blood supply to it. It leads to joint pains and stiffness, and can cause difficulties in movement. If you notice any of these symptoms, speak with your doctor.

• If you buy any medicines, check with a pharmacist that they are suitable to take with your other medicines. This is because some remedies interfere with antiretroviral medicines and stop them from working properly. In particular, do not take the herbal remedy St John's wort.

• If you have diabetes you may need to check your blood sugar (glucose) more frequently, as this medicine can affect the levels of sugar in your blood. Your doctor will advise you about this.

• Om du ska genomgå en operation eller tandbehandling, informera den som utför behandlingen om vilka mediciner du tar.

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