LAMIVUDINE (la MIV yoo deen) treats infections caused by the hepatitis B virus. It works by limiting the spread of the virus in your body. It does not kill the virus and it may still be possible to spread the virus to others. It will not treat colds, the flu, or infections caused by bacteria.
This medicine may be used for other purposes; ask your health care provider or pharmacist if you have questions.

Do not skip doses. Skipping doses can make the hepatitis B virus resistant to this and other medications. Keep taking this therapy unless your care team tells you to stop.

You may need blood work done while you are taking this medication.
Hepatitis B is spread to others through sexual or blood contact. Talk to your care team about how to stop the spread of hepatitis B.
Do not stop taking this medication without first talking to your care team. The symptoms of hepatitis B may worsen when you stop taking this medication. Your care team will check your liver and general health for several months after treatment is stopped.
Make sure you have the correct formulation of this medication. The products used to help manage HIV symptoms contain a higher dose of lamivudine than the products used to treat hepatitis B. It is important that you take the right dose. If you have both HIV and hepatitis B, you need to take the product for HIV. Taking the wrong dose can make HIV change, which can cause the medication to not work as well. This makes it hard to stay healthy.
