1.    What Lamivudine is and what it is used for

Lamivudine is used to treat long term (chronic) hepatitis B infection in adults.

The active ingredient in Lamivudine tablets is lamivudine. Lamivudine is an antiviral drug that suppresses the hepatitis B virus infection and belongs to a group called nucleoside analogue reverse transcriptase inhibitors (NRTIs).

Hepatitis B is a virus which infects the liver, causes long term (chronic) infection, and can lead to liver damage. Lamivudine tablets can be used in people whose liver is damaged, but still functions normally (compensated liver disease) and in people whose liver is damaged and does not function normally (decompensated liver disease).

Treatment with Lamivudine tablets 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 tablets in the same way. Your doctor will monitor the effectiveness of your treatment.

2.    What you need to know before you take Lamivudine tablets

Talk to your doctor if any of these apply to you. You may need extra check-ups, including blood tests, whileyou'retaking your medication. See section 4for more information.

Don't stop taking Lamivudine tablets without yourdoctor's advice, as there is a risk of your hepatitis getting worse. When you stop taking Lamivudine tablets your doctor will monitor you for at least the following four months to check for any problems. This will mean taking blood samples to check for any abnormal liver enzymes, indicating liver damage.

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're taking Lamivudine tablets.

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 tablets 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.

•    Don't risk blood transfer - for example, don't share needles.

There is an effective vaccine available to protect those at risk from becoming infected with hepatitis B virus.

Other medicines and Lamivudine tablets

Tell your doctor or pharmacist if you're taking any other medicines, or ifyou've 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'retaking Lamivudinetablets.

These medicines should not be used with Lamivudine tablets:

•    zalcitabine or lamivudine, used to treat HIV infection (sometimes called the AIDS virus)

•    emtricitabine used to treat HIV or hepatitis B infection

•    cladribine, used to treat hairy cell leukaemia

How much to take

The usual dose of Lamivudine tablets 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 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 tablets (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.

If you take more Lamivudine tablets than you should

Accidentally taking too much Lamivudine tablets is unlikely to cause any serious problems. If you accidentally take too much, tell your doctor or your pharmacist, or contact your nearest hospital emergency department for further advice.
