Full Consumer Medicine Information (CMI)
This leaflet provides important information about taking ZETLAM. You should also speak to your doctor or pharmacist if you would like further information
or if you have any concerns or questions about taking ZETLAM.
Where to find information in this leaflet:
1. Why am I taking ZETLAM?
ZETLAM contains the active ingredient lamivudine. ZETLAM belongs to a group of medicines called antivirals.
ZETLAM is used to treat patients 2 years of age or over with long term (chronic) viral
infection of the liver caused by hepatitis B.
Hepatitis B is a virus which damages the liver. Treatment with ZETLAM can reduce the
amount of hepatitis B virus in your body. This should lead to less liver damage.
ZETLAM has not been shown to reduce the risk of passing hepatitis B to others. You
will still be able to pass on the hepatitis virus by sexual contact or through your
blood. You should use appropriate precautions.
Ask your doctor if you have any questions about why this medicine has been prescribed
for you.
Your doctor may have prescribed it for another reason.
ZETLAM is not addictive.
If you are already taking the medicine lamivudine for HIV infection (3TC™, Combivir™),
your doctor will continue to treat you with the higher dose for that treatment.
2. What should I know before I take ZETLAM?
