1. What Lamivudine Teva is and what it is used for
The active ingredient in Lamivudine Teva is lamivudine.
Lamivudine Teva is used to treat long term (chronic) hepatitis B infection in adults.
Lamivudine Teva is an antiviral medicine that suppresses the hepatitis B virus and belongs to a group of medicines called nucleoside analogue reverse transcriptase inhibitors (NRTIs).
Hepatitis B is a virus that infects the liver causes long term (chronic) infection, and can lead to liver damage. Lamivudine Teva can be used in people whose liver is damaged but still functions normally (compensated liver disease ).
Treatment with Lamivudine Teva can reduce the amount of hepatitis B virus in your body. This should lead to a reduction in liver damage and an improvement in your liver function. Not everyone responds to treatment with Lamivudine Teva in the same way. Your doctor will monitor the effectiveness of your treatment with regular blood tests.
2. What you need to know before you take Lamivudine Teva

-

Warnings and precautions
Some people taking Lamivudine Teva or other similar medicines are more at risk of serious side effects. You need to be aware of the extra risks:
- if you have ever had other types of liver disease, such as hepatitis C.
- if you are seriously overweight (especially if you are a woman).
+ 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 medication. See Section 4 for more information about the risks.
Do not stop taking Lamivudine Teva without your doctor’s advice, as there is a risk of your hepatitis getting worse. When you stop taking Lamivudine Teva your doctor will monitor you for at least four months to check for any problems. This will mean taking blood samples to check for any raised liver enzyme levels, which may indicate liver damage. See section 3 for more information about how to take Lamivudine Teva.
Look out for important symptoms
Some people taking medicines for hepatitis B 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 Teva.
■ ^ Read the information ‘Other possible side effects of therapy for Hepatitis B’ in Section 4 of this leaflet.
Protect other people
Hepatitis B 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 Teva will not stop you passing hepatitis B infection on to other people. To protect other people from becoming infected with hepatitis B:
- Use a condom when you have oral or penetrative sex.
- Do not risk blood transfer — for example, do not share needles.

lactitol or maltitol), if taken regularly
- other medicines containing lamivudine, used to treat HIV infection (sometimes called the AIDS
virus)
- emtricitabine (used to treat HIV or hepatitis B infection)

3. How to take Lamivudine Teva
Always take this medicine exactly as your doctor has told you to. Check with your doctor or pharmacist if you are not sure.

-
■^ Keep in touch with your doctor, and do not stop taking Lamivudine Teva without your doctor’s advice.
How much to take
The usual dose of Lamivudine Teva is one tablet (100 mg lamivudine) once a day.
Your doctor may prescribe a lower dose if you have problems with your kidneys. An oral solution of Lamivudine is available for people who need a lower than usual dose, or who can’t take tablets.
+ Talk to your doctor if this applies to you.
If you are already taking another medicine that contains lamivudine for HIV infection, your doctor will continue to treat you with the higher dose, (usually 150 mg twice a day), because the dose of lamivudine in Lamivudine Teva (100 mg) is not enough to treat HIV infection. If you are planning to change your HIV treatment, discuss this change with your doctor first.
Swallow the tablet whole, with some water. Lamivudine Teva can be taken with or without food.
If you take more Lamivudine Teva than you should
If you accidentally take too much Lamivudine Teva, tell your doctor or pharmacist, or contact your nearest hospital emergency department for further advice. If possible, show them the Lamivudine Teva pack.
If you forget to take Lamivudine Teva
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 missed dose.
Do not stop taking Lamivudine Teva
You must not stop taking Lamivudine Teva without consulting your doctor. There is a risk of your hepatitis getting worse (see section 2). When you stop taking Lamivudine Teva your doctor will monitor you for at least four months to check for any problems. This will mean taking blood samples to check for any raised liver enzyme levels, which may indicate liver damage.
