What is in this leaflet?
Please read this leaflet carefully before you start TELZIR tablets.
This leaflet answers some common questions about TELZIR tablets. It does not contain all of the available information.
It does not take the place of talking to your doctor or pharmacist.
All medicines have benefits and risks. Your doctor has weighed the risks of you taking TELZIR in combination with ritonavir against the expected benefits it will have for you.
As you will be taking TELZIR together with low doses of ritonavir, you should also carefully read the Patient Leaflet for that product before starting treatment with this combination.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.
Keep this leaflet with the tablets.
You may need to read it again.
What TELZIR tablets are used for
TELZIR tablets contain fosamprenavir which belongs to a group of antiretroviral medicines called protease inhibitors.
The low doses of ritonavir you take together with TELZIR are designed to increase the amount of the active ingredient, amprenavir, available to control your HIV infection.
TELZIR, taken with ritonavir, are used together with other antiretroviral medicines to slow down the progression of human immunodeficiency virus (HIV) infection, which can lead to Acquired Immune Deficiency Syndrome (AIDS) and other related illnesses (eg AIDS-related Complex or ARC).
TELZIR does not cure AIDS or kill the HIV virus, but prevents further damage to the immune system by stopping production of new viruses.
TELZIR does not reduce the risk of passing the infection to others. You will still be able to pass on the HIV virus by sexual activity or by contamination with infected blood. You should still use proper precautions to prevent this.
While taking TELZIR and/or any other therapy for HIV disease, you may continue to develop other infections and other complications of HIV infection. You should keep in regular contact with the doctor who is looking after you.
TELZIR tablets are not addictive.
Ask your doctor if you have any questions about why TELZIR tablets have been prescribed for you.
Before you take TELZIR tablets
TELZIR is to be taken in combination with ritonavir. It is therefore important that you carefully read the Package Leaflet that is provided with that medicine. If you have any further questions about ritonavir please ask your doctor or pharmacist.
When you must not take them
- Do not take TELZIR tablets if you have ever had an allergic or hypersensitivity reaction to fosamprenavir or amprenavir or any of the ingredients listed at the end of this leaflet.
- Do not take ritonavir if you have ever had an allergic or hypersensitivity reaction to ritonavir or any of the ingredients found in that medicine.
If you develop any of the symptoms of allergy or hypersensitivity, tell your doctor immediately. If an allergy or hypersensitivity is diagnosed then your doctor may stop your TELZIR and ritonavir treatment.
- Do not take TELZIR tablets if you are pregnant, trying to become pregnant or breastfeeding, unless your doctor says you should.
Your doctor will discuss the risks and benefits of using TELZIR with ritonavir if you are pregnant or breastfeeding.

- astemizole and terfenadine, which are used to treat hayfever

- telaprevir, boceprevir, simeprevir, paritaprevir and similar medicines which are used to treat hepatitis C

Before you start to take it
You must tell your doctor if:

- you have, or have ever had, liver problems, for example jaundice, hepatitis, virus affecting the liver, enlarged liver or liver scarring (cirrhosis).
People with liver disease will need to have their dose of TELZIR and/or ritonavir adjusted. As it is not possible to reduce the dose of TELZIR tablets to less than 700 mg, patients with moderate or severe liver disease must not be treated with TELZIR tablets. If you are unsure about your level of liver disease consult your doctor who may carry out additional testing to see whether the TELZIR/ritonavir combination is suitable for you.
- you have any other illness, for example diabetes mellitus or haemophilia, including those that you think are not related to HIV infection.

How long to take them
Because your medicine helps to control your condition, but does not cure it, you will need to take the tablets every day. Do not stop taking your medicine without first talking to your doctor.
If you forget to take them
If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to. Otherwise, take it as soon as you remember, then go back to taking it as you would normally.
Do not take a double dose to make up for the dose that you missed.
If you take too much (overdose)
Immediately telephone your doctor or Poisons Information Centre (telephone 131126), or go to the Accident and Emergency unit at your nearest hospital, if you think you or anyone else may have taken too many TELZIR tablets. Do this even if there are no signs of discomfort or poisoning.
If you are not sure what to do, contact your doctor or pharmacist.
While you are taking TELZIR tablets
Things you must do
Tell your doctor or pharmacist that you are taking TELZIR tablets if you are about to be started on any other medicines.
Tell your doctor if you become pregnant or are trying to become pregnant.
Tell your doctor if, for any reason, you have not taken your medicine exactly as prescribed.
Otherwise, your doctor may think that it was not effective and change your treatment unnecessarily.
Things you must not do
Do not stop taking TELZIR tablets or ritonavir, or change the dose without first checking with your doctor.
Do not give this medicine to anyone else, even if their symptoms seem similar to yours.
Do not use TELZIR tablets to treat any other complaints unless your doctor says to.

Like all medicines, TELZIR and ritonavir can cause some side-effects. If they occur, they are most likely to be minor and temporary. However, some may be serious and may need medical attention.
Common side-effects associated with TELZIR and ritonavir treatment include:
- nausea & vomiting.
- abdominal pain.
- altered sensation in your mouth.
Occasionally the skin rash may be severe and as a result your doctor may decide that you have to stop taking this medicine.
Other side-effects that have been reported, include:
- muscle pain.
- tenderness and weakness
These have been seen particularly with antiretrovirals therapy including protease inhibitors and nucleoside analogues.
In some individuals, treatment with a combination of antiretroviral medicines that includes a protease inhibitor may find their body shape changes due to an increase in body fat. . 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, speak to your doctor.
Your doctor will test your blood regularly for any abnormalities (blood lipids and sugar). Increases in liver enzymes and blood fats have been reported in patients taking TELZIR and ritonavir.
Within the first few weeks of treatment with anti-HIV medicines, some people, particularly those that have been HIV positive for some time, may develop inflammatory reactions (eg pain, redness, swelling, high temperature) which may resemble an infection and may be severe. It is thought that these reactions are caused by a recovery in the body's ability to fight infections, previously suppressed by HIV. If you become concerned about any new symptoms, or any changes in your health after starting HIV treatment, please discuss with your doctor immediately.
Some people may get other side-effects while taking TELZIR and ritonavir. If you are concerned, talk to your doctor or pharmacist.
Do not be alarmed by this list of possible side-effects. You may not experience any of them.
