Patient leaflet - LAMIVUDINE MYLAN 150 MG FILM-COATED TABLETS
1. What Lamivudine is and what it is used for
Lamivudine is used to treat HIV (human immunodeficiency virus) infection in adults and children.
Lamivudine belongs to a group of antiviral medicines, also known as antiretrovirals, called nucleoside analogue reverse transcriptase inhibitors (NRTIs). Lamivudine 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 CD4 cell count in your blood. CD4 cells are a type of white blood cell that are important in maintaining a healthy immune system to help fight infection.
Response to treatment with lamivudine varies between patients. Your doctor will be monitoring the effectiveness of your treatment.
2. What you need to know before you take Lamivudine
Do not take Lamivudine:
if you are allergic to lamivudine or any of the other
ingredients of this medicine (listed in section 6) Check with your doctor if you think this applies to you.
Warnings and precautions
Talk to your doctor or pharmacist before taking Lamivudine:
if you are currently being treated for HIV with
tenofovir and abacavir or tenofovir and didanosine (other NRTIs)
if you have ever had liver disease, including
hepatitis B or C (if you have hepatitis B infection, do not stop taking Lamivudine without your doctor’s advice, as your hepatitis may come back)
if you are seriously overweight (especially if you
are a woman)
if you or your child has a kidney problem, your
dose may be altered
Talk to your doctor if any of these apply to 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 ‘Other possible side effects
of combination therapy for HIV’ in section 4 of this leaflet.
Other medicines and Lamivudine
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, 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 Lamivudine.
These medicines should not be used with Lamivudine:
medicines (usually liquids) containing sorbitol and
other sugar alcohols (such as xylitol, mannitol, lactitol or maltitol), if taken regularly
other medicines containing lamivudine (used to
treat HIV infection or hepatitis B infection)
a group of medicines called cytidine analogues
used to treat HIV such as emtricitabine
co-trimoxazole (an antibiotic medicine used to
treat infections)
cladribine (used to treat cancer of the blood
(leukaemia))
Tell your doctor if you are being treated with any of these.
Pregnancy and breast-feeding
Pregnancy
If you are pregnant, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. Lamivudine and similar medicines may cause side effects in unborn babies. If you have taken Lamivudine 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
Breast-feeding is not recommended in women living with HIV because HIV infection can be passed on to the baby in breast milk.
A small amount of the ingredients in this medicine can also pass into your breast milk.
If you are breast-feeding or thinking of breast-feeding, you should discuss it with your doctor as soon as possible.
Driving and using machines
Lamivudine is unlikely to affect your ability to drive or use machines.
Lamivudine contains sodium
This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially ‘sodium-free’.

4. 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 life style, 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 everybody gets them. When you are being treated for HIV, it can be hard to tell whether a symptom is a side effect of lamivudine or other medicines you are taking, or an effect of the HIV disease itself. For this reason it is very important that you inform your doctor about any changes in your health.
As well as the side effects listed below for Lamivudine, 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’.
If you notice any of the following serious side
effects contact your doctor immediately: Uncommon (may affect up to 1 in 100 people):
an increase in the number of infections you get
which causes fever, severe chills, sore throat or mouth ulcers. This may be signs you have a low number of white blood cells in your blood (neutropenia).
unexplained bruising or bleeding for longer
than usual. These may be signs of a decrease in the number of cells involved in blood clotting (thrombocytopenia).
Rare (may affect up to 1 in 1,000 people):
swelling in the face, mouth, lips, tongue or
throat causing difficulty breathing or swallowing (angioedema).
severe stomach pain which may radiate to your
back. This may be signs of problems with your pancreas (pancreatitis).
yellowing of your skin or whites of your eyes, dark
urine, pale stools, tiredness, fever, feeling sick (nausea), weakness, drowsiness and abdominal pain. These may be signs you have serious problems with your liver (hepatitis).
dark coloured urine with muscle weakness
or tiredness. These may be signs of muscle breakdown (rhabdomyolysis).
Very rare (may affect up to 1 in 10,000 people):
tiredness, weakness, pale coloured skin, shortness
of breath. These may be signs of a disorder where you are not producing red blood cells (pure red cell aplasia).
numbness and tingling (commonly known as pins
and needles), burning, stabbing or shooting pain in the feet or hands leading to loss of balance and co-ordination. These may be signs of nerve damage (peripheral neuropathy).
deep, rapid, difficult breathing, drowsiness,
numbness or weakness in the limbs, feeling sick (nausea), being sick (vomiting) and stomach pain. These may be signs of excess lactic acid in the blood (lactic acidosis).
Other possible side effects include:
Common (may affect up to 1 in 10 people):
- feeling sick (nausea)
- being sick (vomiting)
- stomach pains
- diarrhoea
- headache
- joint pain
- muscle pain and discomfort

Uncommon (may affect up to 1 in 100 people):
- a low red blood cell count (anaemia)
- an increase in the level of liver enzymes Rare (may affect up to 1 in 1,000 people):
increase in an enzyme called amylase that can be
seen in a blood test
Other possible side effects of combination therapy for HIV
Combination therapy including Lamivudine 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 are taking Lamivudine:
Tell your doctor immediately. Do not take other medicines for the infection without your doctor’s advice.
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. This includes any possible side effects not listed in this leaflet. You can also report side effects directly via Yellow Card Scheme, Website: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store. By reporting side effects you can help provide more information on the safety of this medicine.
