Read all of this leaflet carefully before you start taking this medicine because it contains
important information for you.
Keep this leaflet. You may need to read it again.
If you have any further questions, ask your doctor, pharmacist or nurse.
This medicine has been prescribed for you only. Do not pass it on to others. It may
harm them, even if their signs of illness are the same as yours.
If you get any side effects, talk to your doctor, pharmacist or nurse. This includes any
possible side effects not listed in this leaflet. See section 4.
IMPORTANT — Hypersensitivity reactions
Iviverz contains abacavir (which is also an active substance in other related medicines).
Some people who take abacavir may develop a hypersensitivity reaction (a serious allergic
reaction), which can be life-threatening if they continue to take abacavir containing products.
You must carefully read all the information under ‘Hypersensitivity reactions’ in the
panel in Section 4.
The Iviverz pack includes an Alert Card, to remind you and medical staff about abacavir
hypersensitivity. Detach this card and keep it with you at all times.

1.

What Iviverz is and what it is used for

Iviverz is used to treat HIV (human immunodeficiency virus) infection in adults,
adolescents and in children weighing at least 25kg.
Iviverz contains two active ingredients that are used to treat HIV infection: abacavir and
lamivudine. These belong to a group of anti-retroviral medicines called nucleoside analogue
reverse transcriptase inhibitors (NRTIs).
Iviverz does not completely cure HIV infection; it reduces the amount of virus in your body,
and keeps it at a low level. It also increases the CD4 cell count in your blood. CD4 cells are a
type of white blood cells that are important in helping your body to fight infection.
Not everyone responds to treatment with Iviverz in the same way. Your doctor will monitor
the effectiveness of your treatment.

2.

What you need to know before you take Iviverz

1

Do not take Iviverz:
- if you are allergic (hypersensitive) to abacavir (or any other medicine containing
abacavir), lamivudine or any of the other ingredients of this medicine (listed in section 6).
Carefully read all the information about hypersensitivity reactions in Section 4.
Check with your doctor if you think any of these apply to you. Do not take Iviverz.
Take special care with Iviverz
Some people taking Iviverz or other combination treatments for HIV are more at risk of
serious side effects. You need to be aware of the extra risks:
if you have moderate or severe liver disease
if you have ever had liver disease, including hepatitis B or C (if you have hepatitis B
infection, do not stop Iviverz without your doctor’s advice, as your hepatitis may come
back)
if you are seriously overweight (especially if you are a woman)
if you are diabetic and using insulin
if you have a kidney problem
Talk to your doctor if any of these apply to you before using Iviverz. You may need
extra check-ups, including blood tests, while you are taking your medicine. See Section
4 for more information.
Abacavir hypersensitivity reactions
Even patients who don’t have the HLA-B*5701 gene may still develop a
hypersensitivity reaction (a serious allergic reaction).
Carefully read all the information about hypersensitivity reactions in Section 4 of
this leaflet.
Risk of heart attack
It cannot be excluded that abacavir may increase the risk of having a heart attack.
Tell your doctor if you have heart problems, if you smoke, or have other illnesses that
may increase your risk of heart disease such as high blood pressure, or diabetes. Do not
stop taking Iviverz unless your doctor advises you to do so.
Look out for important symptoms
Some people taking medicines for HIV infection develop other conditions, which can be
serious. You need to know about important signs and symptoms to look out for while you are
taking Iviverz.
Read the information ‘Other possible side effects of combination therapy for HIV’
in Section 4 of this leaflet.
Protect other people
HIV infection is spread by sexual contact with someone who has the infection, or by transfer
of infected blood (for example, by sharing injection needles). You can still pass on HIV when
taking this medicine, although the risk is lowered by effective antiretroviral therapy. Discuss
with your doctor the precautions needed to avoid infecting other people.
Other medicines and Iviverz
Tell your doctor or pharmacist if you are taking any other medicines, or if you have
taken any recently, including herbal medicines or other medicines you bought without a
prescription.
Remember to tell your doctor or pharmacist if you begin taking a new medicine while you are
taking Iviverz.
These medicines should not be used with Iviverz:
2

-

Emtricitabine, to treat HIV infection
other medicinal products containing lamivudine, used to treat HIV infection or hepatitis
B infection
high doses of trimethoprim/sulfamethoxazole, an antibiotic
cladribine, used to treat hairy cell leukaemia
Tell your doctor if you are being treated with any of these.

Some medicines interact with Iviverz
These include:
-

phenytoin, for treating epilepsy.
Tell your doctor if you are taking phenytoin. Your doctor may need to monitor
you while you are taking Iviverz.

-

methadone, used as a heroin substitute. Abacavir increases the rate at which
methadone is removed from the body. If you are taking methadone, you will be checked
for any withdrawal symptoms. Your methadone dose may need to be changed.
Tell your doctor if you are taking methadone.

Pregnancy
Iviverz is not recommended for use during pregnancy. Iviverz and similar medicines may
cause side effects in unborn babies. If you have taken Iviverz during your pregnancy, your
doctor may request regular blood tests and other diagnostic tests to monitor the development
of your child. In children whose mothers took NRTIs during pregnancy, the benefit from the
protection against HIV outweighed the risk of side effects.

Breast-feeding
Women who are HIV-positive must not breast-feed, because HIV infection can be passed
on to the baby in breast milk. A small amount of the ingredients in Iviverz can also pass into
your breast milk.
If you are breast-feeding, or thinking about breast-feeding:
Talk to your doctor immediately.
Driving and using machines
Iviverz may cause side effects which could affect your ability to drive or use machines.
Talk to your doctor about your ability to drive or operate machines while taking
Iviverz.
Important information about some of the other ingredients of Iviverz Tablets
Iviverz contains a colouring called sunset yellow Aluminium Lake (E110), this may cause
allergic reactions in some people.

How to take Iviverz

Always take this medicine exactly as your doctor has told you. Check with your doctor or
pharmacist if you are not sure.
The recommended dose of Iviverz for adults, adolescents and children weighing 25kg or
more is one tablet once a day.
Swallow the tablets whole, with some water. Iviverz can be taken with or without food.
3

Stay in regular contact with your doctor
Iviverz helps to control your condition. You need to keep taking it every day to stop your
illness getting worse. You may still develop other infections and illnesses linked to HIV
infection.
Keep in touch with your doctor, and do not stop taking Iviverz without your doctor’s
advice.
If you take more Iviverz than you should
If you accidentally take too much Iviverz, tell your doctor or your pharmacist, or contact your
nearest hospital emergency department for further advice.
If you forget to take Iviverz
If you forget to take a dose, take it as soon as you remember. Then continue your treatment as
before. Do not take a double dose to make up for a forgotten dose.
It is important to take Iviverz regularly, because if you take it at irregular intervals, you may
be more likely to have a hypersensitivity reaction.
If you have stopped taking Iviverz
If you have stopped taking Iviverz for any reason — especially because you think you are
having side effects, or because you have other illness:
Talk to your doctor before you start taking it again. Your doctor will check whether
your symptoms were related to a hypersensitivity reaction. If the doctor thinks they may
have been related, you will be told never again to take Iviverz, or any other medicine
containing abacavir. It is important that you follow this advice.
If your doctor advises that you can start taking Iviverz again, you may be asked to take your
first doses in a place where you will have ready access to medical care if you need it.

Possible side effects

During HIV therapy there may be an increase in weight and in levels of blood lipids and
glucose. This is partly linked to restored health and lifestyle, and in the case of blood lipids
sometimes to the HIV medicines themselves. Your doctor will test for these changes.
Like all medicines, this medicine can cause side effects, although not everyone gets them.
When you are being treated for HIV, it can be hard to tell whether a symptom is a side effect
of Iviverz or other medicines you are taking, or an effect of the HIV disease itself. So it is
very important to talk to your doctor about any changes in your health.
Even patients who don’t have the HLA-B*5701 gene may still develop a
hypersensitivity reaction (a serious allergic reaction), described in this leaflet in the
panel headed ‘Hypersensitivity reactions’.
It is very important that you read and understand the information about this
serious reaction.
As well as the side effects listed below for Iviverz, other conditions can develop during
combination therapy for HIV.
It is important to read the information later in this section under ‘Other possible side
effects of combination therapy for HIV’.

Hypersensitivity reactions
Iviverz contains abacavir (which is also an active substance in other related medicines).
Abacavir can cause a serious allergic reaction known as a hypersensitivity reaction. These
hypersensitivity reactions have been seen more frequently in people taking medicines that
contain abacavir.
Who gets these reactions?
Anyone taking Iviverz could develop a hypersensitivity reaction to abacavir, which could be
life threatening if they continue to take Iviverz.
You are more likely to develop this reaction if you have a gene called HLA-B*5701 (but you
can get a reaction even if you do not have this gene). You should have been tested for this
gene before Iviverz was prescribed for you. If you know you have this gene, tell your
doctor before you take Iviverz.
About 3 to 4 in every 100 patients treated with abacavir in a clinical trial who did not have the
HLA-B*5701 gene developed a hypersensitivity reaction.
What are the symptoms?
The most common symptoms are:
- fever (high temperature) and skin rash.
Other common symptoms are:
- nausea (feeling sick), vomiting (being sick), diarrhoea, abdominal (stomach) pain, severe
tiredness.
Other symptoms include:
Pains in the joints or muscles, swelling of the neck, shortness of breath, sore throat, cough,
occasional headaches, inflammation of the eye (conjunctivitis), mouth ulcers, low blood
pressure, tingling or numbness of the hands or feet.
If you continue to take Iviverz, the symptoms will get worse, and may be lifethreatening.
When do these reactions happen?
Hypersensitivity reactions can start at any time during treatment with Iviverz, but are more
likely during the first 6 weeks of treatment.
Contact your doctor immediately:
1.
if you get a skin rash, OR
2.
if you get symptoms from at least 2 of the following groups:
fever
shortness of breath, sore throat or cough
nausea or vomiting, diarrhoea or abdominal pain
severe tiredness or achiness, or generally feeling ill.
Your doctor may advise you to stop taking Iviverz.
If you have stopped taking Iviverz
If you have stopped taking Iviverz because of a hypersensitivity reaction, you must NEVER
AGAIN take Iviverz, or any other medicine containing abacavir. If you do, within hours,
your blood pressure could fall dangerously low, which could result in death.
5

If you have stopped taking Iviverz for any reason — especially because you think you are
having side effects, or because you have other illness:
Talk to your doctor before you start again. Your doctor will check whether your symptoms
were related to a hypersensitivity reaction. If the doctor thinks they may have been, you will
then be told never again to take Iviverz, or any other medicine containing abacavir. It is
important that you follow this advice.
Occasionally hypersensitivity reactions have developed in people who start taking abacavir
containing products again, but who had only one symptom on the Alert Card before they
stopped taking it.
Very rarely patients who have taken medicines containing abacavir in the past without any
symptoms of hypersensitivity have developed a hypersensitivity reaction when they start
taking these medicines again.
If your doctor advises that you can start taking Iviverz again, you may be asked to take your
first doses in a place where you will have ready access to medical care if you need it.
If you are hypersensitive to Iviverz, return all your unused Iviverz tablets for safe
disposal. Ask your doctor or pharmacist for advice.
The Iviverz pack includes an Alert Card, to remind you and medical staff about
hypersensitivity reactions. Detach this card and keep it with you at all times.

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 possible side effects of combination therapy for HIV
Combination therapy such as Iviverz may cause other conditions to develop during HIV
treatment.
Symptoms of infection and inflammation
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). Such infections may have been
“silent” and not detected by the weak immune system before treatment was started. After
starting treatment, the immune system becomes stronger, and may attack the infections, which
can cause symptoms of infection or inflammation. Symptoms usually include fever, plus
some of the following:
- headache
- stomach ache
- difficulty breathing
In rare cases, as the immune system becomes stronger, it can also attack healthy body tissue
(autoimmune disorders). The symptoms of autoimmune disorders may develop many months
after you start taking medicine to treat your HIV infection. Symptoms may include:
- palpitations (rapid or irregular heartbeat) or tremor
- hyperactivity (excessive restlessness and movement)
- weakness beginning in the hands and feet and moving up towards the trunk of the
body.
If you get any symptoms of infection and inflammation or if you notice any of the
symptoms above:
Tell your doctor immediately. Do not take other medicines for the infection without
your doctor’s advice.
7

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 of osteonecrosis 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.

Reporting of side effects
If you get any side effects, talk to your doctor or pharmacist or nurse. This includes any
possible side effects not listed in this leaflet. You can also report side effects directly via the
Yellow Card Scheme Website: www.mhra.gov.uk/yellowcard
By reporting side effects you can help provide more information on the safety of this
medicine.
