Patient’s Leaflet

What is it and how is it used?

Telzir is used to treat HIV (human immunodeficiency virus) infection.

Telzir is a type of medicine known as an anti-retroviral. It is taken with low doses of another medicine, ritonavir, which boosts the level of Telzir in the blood. Telzir belongs to a group of anti-retroviral medicines called protease inhibitors. Protease is an enzyme produced by HIV which enables the virus to multiply in white blood cells (CD4 cells) in your blood. By stopping protease from working, Telzir stops HIV multiplying and infecting more CD4 cells

Telzir with low doses of ritonavir is used in combination with other anti-retroviral medicines (?combination therapy?) to treat adults, adolescents and children aged over 6 years infected with HIV.

HIV can become resistant to anti-HIV medicines. To avoid this happening, and to stop your illness getting worse, it is very important that you keep taking all your medicines exactly as prescribed.

Telzir will not stop you passing on HIV. HIV infection is spread by sexual contact with someone who?s got the infection, or by transfer of infected blood (for example by sharing needles).


What do you have to consider before using it?

Telzir is to be taken in combination with low doses of ritonavir and other antiretroviral medicines. It is therefore important that you carefully read the package leaflet provided with these medicines. If you have any further questions about ritonavir or the other medicines prescribed, please ask your doctor or pharmacist.

Don?t take Telzir:
  • if you are allergic ( hypersensitive) to fosamprenavir, amprenavir or any of the other ingredients in Telzir (listed in section 6), or to ritonavir.
  • if you are taking any of these medicines:
  • astemizole or terfenadine (commonly used to treat allergy symptoms ? these medicines may be available without prescription)
  • pimozid e (used to treat schizophrenia)
  • cisapride (used to relieve indigestion)
  • ergot derivatives (used to treat headaches)
  • rifampicin (used to treat tuberculosis)
  • amiodarone, quinidine, flecainide and propafenone ( heart medicines)
  • bepridil (used to treat high blood pressure).
  • oral midazolam or oral triazolam (used to treat anxiety)
  • products containing St John?s wort ( Hypericum perforatum).

? Tell your doctor if any of these applies to you.

Take special care with Telzir
Before you take Telzir
your doctor needs to know :

  • If you have a known allergy to medicines containingsulphonamide. You may also be allergic to Telzir.
  • If you have liver disease. Your doctor may lower your dose of Telzir and ritonavir depending on the amount of liver damage. You will be monitored while you are taking Telzir. If your liver disease gets worse, you may need to stop taking Telzir for a while, or permanently. People with hepatitis B or C taking combination therapy are at increased risk of getting severe liver problems.
  • If you have haemophilia. Increased bleeding may occur while taking protease inhibitors (such as Telzir). The reason for this is not known. You may need additional factor VIII to control any bleeding.
  • If you have diabetes. In some patients taking antiretroviral medicines including protease inhibitors, there have been reports of increased sugar in the blood and diabetes getting worse. Also, some people have become diabetic while taking these medicines.
  • If you are taking any other medicines. See section ?Other medicines and Telzir? below.

? Tell your doctor if any of these applies to you. You will need extra check-ups, including blood tests, while you?re taking your medication.

Your doctor will monitor your blood glucose levels before and during treatment with Telzir.

Look out for important symptoms

Some people taking medicines for HIV infection develop other conditions, which can be serious. These include:

  • Flare up of old infections
  • Change in your body shape
  • Problems with your bones. You need to know about important signs and symptoms to look out for while you?re taking Telzir. Please read the information on ?Other side effects of combination therapy for HIV? in section 4 of this leaflet. If you have any questions about this information or the advice given: ? Talk to your doctor.

You may get a skin rash.

However you can still continue to take Telzir.It can be treated with antihistamines. Rarely, the skin rash can be severe and serious ( Stevens Johnson syndrome). If this happens, Telzir must be stopped immediately and you must never take it again.

Protect other people

Telzir will not stop you passing HIV infection on to other people, by having sex or by blood transfer. To protect other people from becoming infected with HIV:
? Use a condom when you have oral or penetrative sex.
? Don?t risk blood transfer ? for example, don?t share needles.

Other medicines and Telzir
Tell your doctor or pharmacist if you?re taking any other medicines, if you?ve taken any recently, or if you start taking new ones
? these include herbal medicines or other medicines you bought without a prescription.
Your doctor will decide if these medicines are suitable for you to take with Telzir and ritonavir. This is very important, as Telzir or ritonavir can strengthen or weaken the effects of other medicines. This can sometimes lead to serious medical conditions.

What are possible side effects?

Like all medicines, Telzir can cause side effects, but not everyone gets them. When treating HIV, it can be hard to tell whether side effects are caused by Telzir, by other medicines taken at the same time or by the HIV disease itself. For this reason, it is very important to talk to your doctor about any changes in your health.

Very common side effects
These may affect more than 1 in 10 people:

  • Diarrhoea ?
  • Increase in cholesterol (a type of blood fat). Your doctor will monitor your blood fat levels before and during treatment with Telzir.

Common side effects
These may affect up to 1 in 10people:

  • Increases in triglycerides (a type of blood fat). Your doctor will monitor your blood fat levels before and during treatment with Telzir.
  • Feeling sick or being sick ( nausea or vomiting), pain in the stomach, loose stools
  • Skin rashes (red, raised or itchy) ? if the skin rash is severe, you may have to stop taking this medicine
  • Headache, feeling dizzy
  • Feeling tired
  • Increases in enzymes produced by the liver called transaminases, increases of an enzyme produced by the pancreas called lipase.
  • Tingling or numbness around the lips and mouth.

Uncommon side effects
These may affect up to 1 in 100 people:

  • Swelling of the face, lips and tongue ( angioedema).

Rare side effects
These may affect up to 1 in 1000 people:

  • A severe or life-threatening skin reaction ( Stevens Johnson syndrome).

You may experience muscle problems

There have been reports of muscle pain, tenderness or weakness, particularly with antiretroviral therapy including protease inhibitors and nucleoside analogues. On rare occasions, these muscle disorders have been serious ( rhabdomyolysis). If you notice any muscle problems:? Tell your doctor.

Haemophiliacs may bleed more

In patients with haemophilia type A and B, there have been reports of increased bleeding while taking protease inhibitors. If this happens to you:
? Talk to your doctor immediately.

If you get side effects

? Tell your doctor or pharmacist if any of the side effects gets severe or troublesome, or if you notice any side effects not listed in this leaflet.

Other side effects of combination therapy for HIV

Old infections may flare up

People with advanced HIV infection (AIDS) have weak immune systems and are more likely to develop serious infections (opportunistic infections). When these people start treatment, they may find that old, hidden infections flare up, causing signs and symptoms of inflammation. These symptoms are probably caused by the body?s immune system becoming stronger, so that the body starts to fight these infections.

If you get any symptoms of infection or signs of inflammation while you?re taking Telzir: ? Tell your doctor immediately. Don?t take other medicines for the infection without your doctor?s advice.

Your body shape may change

People taking combination therapy may find that their body shape changes, because of changes in fat distribution:

  • Fat may be lost from the legs, arms or face
  • Extra fat may build up around the tummy (abdomen) or the breasts or internal organs
  • Fatty lumps (sometimes called a buffalo hump) may appear on the back of the neck.

It is not yet known what causes these changes, or whether they have any long-term effects on your health. If you notice changes in your body shape:
? Tell your doctor.

You may have problems with your bones

Some people taking combination therapy for HIV develop a condition called osteonecrosis. With this condition, parts of the bone tissue die because of reduced blood supply to the bone.

People may be more likely to get this condition:

  • if they have been taking combination therapy for a long time
  • if they are also taking anti-inflammatory medicines called corticosteroids
  • if they drink alcohol
  • if their immune systems are very weak
  • if they are overweight. Signs to look out for include:
  • stiffness in the joints
  • aches and pains (especially in the hip, knee or shoulder)
  • difficulty moving. If you notice any of these symptoms: Tell your doctor.

Other effects may show up in tests

Combination therapy for HIV can also cause:

  • increased levels of lactic acid in the blood
  • increased levels of sugar or fats in the blood
  • resistance to insulin (so if you?re diabetic, you may have to change your insulin dose to control your blood sugar).
