• Lamivudine may cause drowsiness or dizziness. Do not drive, operate machinery, or do anything else that could be dangerous until you know how you react to Lamivudine. Using Lamivudine alone, with certain other medicines, or with alcohol may lessen your ability to drive or to perform other potentially dangerous tasks.
• Your doctor will offer you counseling and testing for HIV infection (the virus that causes AIDS) before treatment with Lamivudine and periodically during treatment. You should not take Lamivudine if you have HIV infection. If you have both hepatitis B virus and HIV, make sure that your doctor knows you have both infections. If you are prescribed lamivudine, you should only use the medicine that is for HIV treatment ( Epivir ). The lower dose of lamivudine in Lamivudine could make the HIV infection harder to treat.
• Lamivudine is not a cure for hepatitis B virus infection. It is unknown if Lamivudine reduces the risk of liver cancer or cirrhosis that may be caused by hepatitis B virus. Some patients developed hepatitis B virus that is resistant to Lamivudine. These patients had less benefit from Lamivudine and some experienced worsening of hepatitis after the resistant virus appeared.
• Your doctor will perform lab tests for several months after you stop taking Lamivudine. Some patients have had worsening hepatitis B virus after stopping use of Lamivudine. Tell your doctor about any new or unusual symptoms that you notice after stopping treatment.
• Lamivudine has not been shown to reduce the risk of passing hepatitis B to other people through sexual contact or blood contamination. Use barrier forms of contraception (eg, condoms) if you are infected with hepatitis B virus.
• Diabetes patients - Lamivudine contains sucrose and may affect your blood sugar. Check blood sugar levels closely and ask your doctor before adjusting the dose of your diabetes medicine.
• LAB TESTS, including liver and kidney function tests, may be required to monitor your progress. Be sure to keep all doctor and lab appointments.
