What KIVEXA tablets are used for
KIVEXA tablets contain abacavir and lamivudine which belong to a group of medicines
called antiretrovirals. These are also available as separate medicinal products: ZIAGEN
(abacavir) and 3TC (lamivudine).
KIVEXA tablets are used together with other antiretrovirals 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
KIVEXA tablets do not cure AIDS or kill the HIV virus, but delays further damage to
the immune system by stopping production of new viruses.
KIVEXA tablets do 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 KIVEXA tablets 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.
KIVEXA tablets are not addictive.
Before you take KIVEXA tablets
Do not take if:
You must not take KIVEXA tablets if:
you have ever had an allergic reaction to abacavir, which is also included in medicines
called TRIUMEQ, TRIZIVIR and ZIAGEN
if you are allergic to the active ingredient lamivudine or any of the other ingredients
listed toward the end of this leaflet.
if you have a serious liver disease KIVEXA may not be suitable for you.
KIVEXA contains abacavir. Abacavir can cause a serious allergic reaction known as
a hypersensitivity reaction, which can be life-threatening if treatment with abacavir
containing products is not stopped.
Research has found that people with a gene called HLA-B (type 5701) are more likely
to have a hypersensitivity reaction to abacavir. However, even if you do not have
this gene type it is still possible for you to get this reaction. If you know you
have this gene type, be sure to tell your doctor before you take abacavir.
The most common symptoms of this reaction include high temperature (fever) and a skin
rash. Other most frequently seen symptoms include nausea, vomiting, diarrhoea or abdominal
pain; severe tiredness or body aches or generally feeling ill; headache; shortness
of breath, sore throat or cough. If you develop any of these symptoms call your doctor
IMMEDIATELY WHO WILL ADVISE YOU WHETHER YOU SHOULD STOP TAKING KIVEXA tablets. If
your doctor is not available you must urgently seek other medical advice (eg. the
Accident and Emergency unit of the nearest hospital) before taking the next dose.
Other symptoms may include joint or muscle pain, swelling of the neck or itchy skin.
Occasionally inflammation of the eye (conjunctivitis), ulcers in the mouth, tingling
or numbness of the hands or feet or low blood pressure may occur. The symptoms of
this allergic reaction can occur at any time during treatment with KIVEXA tablets.
However they usually occur in the first six weeks of treatment, and get worse with
If you have had this serious reaction to KIVEXA tablets, NEVER take KIVEXA or any
other medicinal product containing abacavir (TRIZIVIR, ZIAGEN and TRIUMEQ) again as
within hours you may experience a life-threatening lowering of your blood pressure
Occasionally life threatening hypersensitivity reactions have occurred when KIVEXA
tablets was restarted in patients who reported only one of the symptoms on the Alert
Card before stopping.
On very rare occasions, hypersensitivity has been reported when KIVEXA tablets were
re-started in patients who had no symptoms of hypersensitivity before stopping.
If you have stopped taking KIVEXA tablets for any reason it is important that you
contact your doctor before restarting. This is especially so if you think you are
having side-effects from other medicines or have another illness. Your doctor will
check whether any symptoms you had before stopping may be related to this hypersensitivity
reaction. If your doctor thinks there is a possibility that they were related, you
may be told never to take KIVEXA tablets again. It is important that you follow this
If you are hypersensitive to KIVEXA tablets you should return all of your unused KIVEXA
tablets to your doctor or pharmacist for proper disposal.
You must not take KIVEXA tablets if:
you had a previous allergic reaction to KIVEXA tablets or other abacavir containing
products (ZIAGEN, TRIZIVIR and TRIUMEQ).
you are pregnant, think you may be pregnant or are breastfeeding, unless your doctor
tells you to.
the expiry date (EXP.) printed on the pack has passed.
the packaging is torn or shows signs of tampering.
You must tell your doctor if:
you are allergic to foods, dyes, preservatives or any other medicines.
you have any other illness.
you are taking any other medicines, including medicines you buy without a prescription
from a supermarket or health food shop.
Abacavir or lamivudine in KIVEXA tablets may interact with certain other medicines.
KIVEXA tablets should not be taken with emtricitabine.
Some medicines may affect how KIVEXA works, or make it more likely that you'll have
side effects. These medicines include:
sorbitol-containing medicines (usually liquids) used regularly
trimethoprim-sulphamethoxazole (also known as co-trimoxazole), (an antibiotic used
to treat Pneumocystis jiroveci pneumonia (often referred to as PCP) or toxoplasmosis).
Tell your doctor or pharmacist if you are taking any of these.
If you are taking methadone, your doctor may need to adjust your methadone dose, as
abacavir increases the rate at which methadone leaves your body. This is unlikely
to affect most methadone users.

and the possible side effects of KIVEXA tablets before considering driving or using
What are the side-effects?
Check with your doctor as soon as possible if you think you are experiencing any side-effects
or allergic reactions while taking KIVEXA tablets, even if the problem is not listed
in this leaflet.
Like all medicines, KIVEXA tablets 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
KIVEXA contains abacavir (which is also an active ingredient in ZIAGEN, TRIZIVIR and
Abacavir can cause a serious allergic reaction known as a hypersensitivity reaction,
which can be life-threatening if treatment with abacavir containing products is not
stopped. This is described in the section "Special warning" under "Before you take
KIVEXA tablets", of this leaflet.
It is important that you read and understand the information about this serious reaction.
As KIVEXA tablets contains both abacavir and lamivudine, the side effects reported
for each of these have been combined.
The most common side-effects (could affect at least one to ten in every 100 people)
upper abdominal pain
lethargy, fatigue, loss of appetite
joint and muscle pain
skin rash (without any other illness).
Uncommon side-effects (could affect less than one in every 100 people) are:
increases in enzymes produced by the liver
anaemia (low red blood cell count)
neutropenia (low white blood cell count)
reduction in the number of platelets (blood cells important for blood clotting).
If the production of red blood cells is reduced, you may have symptoms of tiredness
A reduction in your white blood cell count can make you more prone to infection. If
you have a low platelet count, you may notice that you bruise more easily.
Rare side-effects (could affect less than one in every 1,000 people) are:
breakdown of muscle tissue, increases of an enzyme called amylase
inflammation of the pancreas (pancreatitis).
Very rare side-effects (could affect less than one in every 10,000 people) are:
serious skin reactions
Changes in the amounts of fatty substances and glucose in the blood have also been
reported. 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.
In babies and infants exposed to Nucleoside Reverse Transcriptase Inhibitors (NRTIs)
during pregnancy or labour small temporary increases in blood levels of a substance
called lactate have been observed. Additionally there have been very rare reports
of diseases that affect the nervous system such as a delayed development and seizures.
Overall, in children whose mothers took NRTIs during pregnancy, the benefit from the
reduced chance of being infected with HIV is likely to be greater than the risk of
suffering from side effects.
Call your doctor IMMEDIATELY if you notice any of the following. The doctor will tell
you whether you should stop taking KIVEXA tablets and what you should do:
Some people taking KIVEXA, or other medicines like it (NRTIs), develop a condition
called lactic acidosis, together with an enlarged liver.
Lactic acidosis is caused by a build-up of lactic acid in the body. It is rare; if
it happens, it usually develops after a few months of treatment. It can be life-threatening,
causing failure of internal organs.
Lactic acidosis is more likely to develop in people who have liver disease, especially
Signs of lactic acidosis include:
- deep, rapid, difficult breathing
- numbness or weakness in the limbs
- feeling sick (nausea), being sick (vomiting)
Allergic (anaphylactic) reaction
The symptoms of an allergic (anaphylactic) reaction which may occur soon after starting
KIVEXA include wheezing, swelling of the lips/mouth, difficulty in breathing, hayfever,
lumpy rash (hives) or fainting.
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.
Fat gain and loss
Fat gain and loss has been observed with combined antiretroviral therapy. A causal
relationship for this has not been established. Should any change in body shape be
noticed, seek medical advice.
This is not a complete list of all possible side-effects. Others may occur in some
people and there may be some side-effects not yet known.
Do not be alarmed by this list of possible side-effects. You may not experience any
