6. Contents of the pack and other information
1. 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
2. What you need to know before you take
Do not take Lamivudine/Zidovudine:
• if you are allergic 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 (neutropenia).
Check with your doctor if you think any of these apply to you.
Warnings and precautions
Talk to your doctor or pharmacist before taking
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, don’t stop
Lamivudine/Zidovudine without your doctor’s advice, as your
hepatitis may come back)
if you have kidney disease
if you are seriously overweight (especially if you’re a woman)
if you’re 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’re 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’re taking
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). 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 sex
Don’t risk blood transfer – for example, don’t share needles.

Other medicines and Lamivudine/Zidovudine
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’re taking Lamivudine/Zidovudine.
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 infections
• high doses of co-trimoxazole, an antibiotic.
• cladribine, used to treat hairy cell leukaemia
Tell your doctor if you’re being treated with any of these.
Some medicines can make it more likely that you’ll have side
effects, or make side effects worse. 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 infections
• fluconazole or flucytosine, to treat fungal infections such as
• pentamidine or atovaquone to treat parasitic infections such as
• amphotericin or co-trimoxazole, to treat fungal and bacterial

advice before taking this medicine.
Lamivudine/Zidovudine and similar medicines may cause side
effects in unborn babies. If you become pregnant while you’re
taking Lamivudine/Zidovudine, your baby may be given extra
check-ups (including blood tests) to make sure it is developing
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 you’re breast-feeding or thinking about breast-feeding:
Talk to your doctor immediately.

4. Possible side effects
Like all medicines, this medicine can cause side effects, although
not everybody gets them.
When you’re being treated for HIV, it can be hard to tell whether a
symptom is a side effect of Lamivudine/Zidovudine or other
medicines you’re 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.
As well as the side effects listed below for
Lamivudine/Zidovudine, other conditions can develop during
combination therapy for HIV.
It is important to read the information later in this section under

See your doctor as soon as possible.
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
• 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.
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 you’re 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 (see details below). By reporting

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 body’s 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, weakness 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 treatment.
If you get any symptoms of infection while you’re taking
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 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.
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, or in obese (very overweight) people, especially
