What Lamivudine/Zidovudine is
and what it is used for

Lamivudine/Zidovudine is used to treat HIV
(human immunodeficiency virus) infection in
adults and children.

Lamivudine/Zidovudine contains two active
ingredients that are used to treat HIV infection:
lamivudine and zidovudine. Both of these belong to a
group of anti-retroviral medicines called nucleoside
analogue reverse transcriptase inhibitors (NRTIs).
Lamivudine/Zidovudine 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
Lamivudine/Zidovudine in the same way. Your doctor
will monitor the effectiveness of your treatment.


What you need to know before you
take Lamivudine/Zidovudine

Do not take Lamivudine/Zidovudine:

• if youʼre allergic (hypersensitive) to lamivudine or
zidovudine, or any of the other ingredients of this
medicine (listed in Section 6).
• if you have a very low red blood cell count
(anaemia) or a very low white blood cell count
Check with your doctor if you think any of these
apply to you.

Take special care with Lamivudine/

Some people taking Lamivudine/Zidovudine 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 ever had liver disease, including
hepatitis B or C (if you have hepatitis B infection,
do not stop Lamivudine/Zidovudine without your
doctorʼs advice, as your hepatitis may come back).
• if you have kidney disease.
• if you are seriously overweight (especially if you
are a woman).
• if you are diabetic and using insulin.
Talk to your doctor if any of these apply to you.
Your doctor will decide if the active substances are
suitable for you. You may need extra check-ups,
including blood tests, while you are taking your
medicine. See Section 4 for more information.
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 Lamivudine/
Read the information ʻOther possible side
effects of combination therapy for HIVʼ 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). Lamivudine/Zidovudine will not stop you
passing HIV infection on to other people. To protect
other people from becoming infected with HIV:
• Use a condom when you have oral or penetrative
• Donʼt risk blood transfer – for example, donʼt
share needles.

Other medicines and Lamivudine/

Tell your doctor or pharmacist if youʼre taking
any other medicines, or if youʼve 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

These medicines should not be used with
• other medicinal products containing lamivudine, to
treat HIV infection or hepatitis B infection
• emtricitabine, to treat HIV infection
• stavudine or zalcitabine, to treat HIV infection
• ribavirin or injections of ganciclovir to treat viral
• high doses of co-trimoxazole, an antibiotic
• cladribine, used to treat hairy cell leukaemia.
Tell your doctor if you are being treated with any
of these.
Some medicines can make it more likely that
youʼll have side effects, or make side effects
These include:
• sodium valproate, to treat epilepsy
• interferon, to treat viral infections
• pyrimethamine, to treat malaria and other
parasitic infections
• dapsone, to prevent pneumonia and treat skin
• fluconazole or flucytosine, to treat fungal
infections such as candida
• pentamidine or atovaquone to treat parasitic
infections such as PCP

and given with some antibiotics to make them
more effective
• methadone, used as a heroin substitute
• vincristine, vinblastine or doxorubicin, to treat
Tell your doctor if you are taking any of these.

Some medicines interact with Lamivudine/
These include:
• clarithromycin, an antibiotic
If youʼre taking clarithromycin, take your dose at
least 2 hours before or after you take your
• phenytoin, for treating epilepsy.
Tell your doctor if youʼre taking phenytoin. Your
doctor may need to monitor you while youʼre
taking Lamivudine/Zidovudine.


If you are pregnant, if you become pregnant or if you
are planning to become pregnant talk to your doctor
about the risks and benefits to you and your baby of
taking Lamivudine/Zidovudine.

Lamivudine/Zidovudine and similar medicines may
cause side effects in unborn babies. If you become
pregnant while youʼre taking Lamivudine/Zidovudine,
your baby may be given extra check-ups (including
blood tests) to make sure it is developing normally.
Children whose mothers took NRTIs (medicines like
Lamivudine/Zidovudine) during pregnancy had a
reduced risk of being infected with HIV. This benefit
is greater than the risk of having side effects.


Women who are HIV-positive must not
breast-feed, because HIV infection can be passed
on to the baby in breast milk.
If youʼre breast-feeding or thinking about
Talk to your doctor immediately.

Driving and using machines

Lamivudine/Zidovudine can make you dizzy and
have other side effects that make you less alert.
Donʼt drive or operate machines unless youʼre
feeling well.

Possible side effects

Like all medicines, Lamivudine/Zidovudine can
cause side effects, but not everyone gets them.

When youʼre being treated for HIV, it can be hard to
tell whether a symptom is a side effect of
Lamivudine/Zidovudine or other medicines youʼre
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.

Other possible side effects of combination
therapy for HIV
Combination therapy such as Lamivudine/
Zidovudine may cause other conditions to develop
during HIV treatment.

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 bodyʼs immune system
becoming stronger, so that the body starts to fight
these infections.
In addition to the opportunistic infections,
autoimmune disorders (a condition that occurs when
the immune system attacks healthy body tissue) may
also occur after you start taking medicines for the
treatment of your HIV infection. Autoimmune
disorders may occur many months after the start of
treatment. If you notice any symptoms of infection or
other symptoms such as muscle weakness,
weakenss beginning in the hands and feet and
moving up towards the trunk of the body,
palpitations, tremor or hyperactivity, please inform
your doctor immediately to seek necessary
If you get any symptoms of infection while youʼre
taking Lamivudine/Zidovudine:
Tell your doctor immediately. Donʼt take other
medicines for the infection without your doctorʼs
Your body shape may change
People taking combination therapy for HIV 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 on the breasts or internal organs
• Fatty lumps (sometimes called 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.

Lactic acidosis is a rare but serious side effect
Some people taking Lamivudine/Zidovudine, or other
medicines like it (NRTIs), develop a condition called
lactic acidosis, together with an enlarged liver.

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
• difficulty moving.
If you notice any of these symptoms:
Tell your doctor.

Other effects may show up in blood tests
Combination therapy for HIV can also cause:
• increased levels of lactic acid in the blood,
which on rare occasions can lead to lactic acidosis
• increased levels of sugar and fats (triglycerides
and cholesterol) in the blood
• resistance to insulin (so if youʼre diabetic, you
may have to change your insulin dose to control
your blood sugar).
Reporting of side effects
If you get any side effects, talk to your doctor or
pharmacist. This includes any possible side effects
not listed in this leaflet. You can also report side
effects directly via the Yellow Card Scheme
By reporting side effects you can help provide more
information on the safety of this medicine.

Lactic acidosis is caused by a buildup 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, or in obese (very
overweight) people, especially women.

Signs of lactic acidosis include:
• deep, rapid, difficult breathing
• drowsiness
• numbness or weakness in the limbs
• feeling sick (nausea), being sick (vomiting)
• stomach pain.
During your treatment, your doctor will monitor you
for signs of lactic acidosis. If you have any of the
symptoms listed above, or any other symptoms that
worry you:
See your doctor as soon as possible.
