Lamivudina Normon belongs to a group of medicines called antivirals. It is used for the treatment of the infection caused by the hepatitis B virus. The hepatitis B virus infects the liver and causes liver damage. Lamivudina Normon may be used in patients whose liver is damaged but still functioning (compensated liver disease) and in patients whose liver is damaged and not functioning normally (decompensated liver disease).

Lamivudina Normon is used to treat patients aged 18 years or older with chronic hepatitis B.

Treatment with Lamivudina Normon may reduce the amount of hepatitis B virus in your body. This would lead to a reduction in liver damage and an improvement in liver function.

• Do not take Lamivudina Normon

• If you are allergic (hypersensitive) to lamivudine or to any of the other components of Lamivudina Normon.

If you are unsure, consult your doctor.

• Warnings and precautions

Consult your doctor or pharmacist before starting to take Lamivudina Normon.

Lamivudina Normon reduces the amount of hepatitis B virus in your body and keeps liver disease under control, thus reducing future health problems related to your liver. For the treatment to be effective, you must take Lamivudina Normon every day. Patients respond to treatment differently, so it is not known for how long you will have to take this medication.

Your doctor will monitor your response to treatment by performing regular blood tests. The results of these tests will help your doctor decide when to stop your treatment with Lamivudina Normon.

Before starting treatment with Lamivudina Normon, you must inform your doctor of any additional medical conditions you have. If you have kidney problems, your doctor may need to reduce the dose of this medication, as your kidneys are mainly responsible for eliminating the medication from your body.

Do not stop taking Lamivudina Normon unless your doctor tells you to, as there is a small risk that your hepatitis will worsen. When you stop taking Lamivudina Normon, your doctor will monitor you for at least the next four months to check if there are any problems. This will involve taking blood samples to check for any abnormalities in liver enzymes indicative of liver damage.

The active ingredient of this product is lamivudine. If you are already taking this medication for HIV infection, your doctor will continue to treat you with the higher dose, usually 150 mg twice a day, as the lower dose of 100 mg is not sufficient to treat HIV infection.

Since your medication helps control your hepatitis B and it is still unknown whether it can cure it, there is a risk that you may transmit this virus to others through sexual contact or through blood, so you must take the necessary precautions to avoid it. There is an effective vaccine available to protect those at risk of infection with the hepatitis B virus.

The class of medications to which lamivudine belongs (NRTIs) may cause a condition called lactic acidosis (creation of lactic acid in the body), along with liver enlargement. Lactic acidosis, if it occurs, usually develops after a few months of treatment. Deep and rapid breathing, drowsiness, and non-specific symptoms such as nausea, vomiting, and stomach pain may indicate the development of lactic acidosis. This rare but serious adverse reaction occurs more frequently in women, especially if they are overweight. If you have liver disease, you may also be at a higher risk of developing this state. While you are taking Lamivudina Normon, your doctor will closely monitor any signs that may indicate you are developing lactic acidosis.
