1. What is Lamivudine Normon and what is it used for

Lamivudine Normon belongs to a group of medications called antivirals. It is used to treat the infection caused by the hepatitis B virus. The hepatitis B virus infects the liver and causes liver damage. Lamivudine Normon can be used in patients whose liver is damaged but still functions (compensated liver disease) and in patients whose liver is damaged and does not function normally (decompensated liver disease).

Lamivudine Normon is used to treat patients aged 18 years and older with chronic (long-term) hepatitis B.

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

2. What you need to know before taking Lamivudine Normon

  • Do not take Lamivudine Normon
  • If you are allergic (hypersensitive) to lamivudine or any of the other ingredients of Lamivudine Normon.

If you are unsure, consult your doctor.

  • Warnings and Precautions

Consult your doctor or pharmacist before starting treatment with Lamivudine Normon.

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

Your doctor will closely 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 Lamivudine Normon.

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

Do not stop taking Lamivudine Normon unless your doctor tells you to, as there is a small risk that your hepatitis may worsen. When you stop taking Lamivudine Normon, your doctor will monitor you for at least the next four months to check for 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 highest 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 not yet known if 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 appropriate precautions to avoid this. 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) can cause a condition called lactic acidosis (production 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 have a higher risk of developing this condition. While you are being treated with Lamivudine Normon, your doctor will closely monitor any signs that may indicate you are developing lactic acidosis.

  • Taking Lamivudine Normon with other medications

Some medications may affect the action of Lamivudine Normon. Inform your doctor or pharmacist that you are taking, have recently taken, or may need to take any other medication.

Lamivudine Normon should not be taken with:

  • emtricitabine (used to treat HIV or hepatitis B infection)
  • Taking Lamivudine Normon with food and drinks

  • Pregnancy and Breastfeeding

Use during pregnancy

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medication. Your doctor will tell you whether you should continue taking Lamivudine Normon while pregnant. Do not stop treatment with Lamivudine Normon without your doctor's advice.

Use during breastfeeding

The components of Lamivudine Normon may pass into breast milk. If you are breastfeeding, you must talk to your doctorbefore taking Lamivudine Normon.

  • Driving and using machines

No studies have been conducted on the effect of Lamivudine Normon on the ability to drive and use machines.

  • Lamivudine Normon contains sodium

3. How to take Lamivudine Normon

The recommended dose of Lamivudine Normon is one tablet (100 mg of lamivudine) once a day. The tablet should be swallowed whole with water. It can be taken with food or on an empty stomach.

Your doctor will tell you how long you need to take your medication.

Your doctor may need to reduce your dose of Lamivudine Normon if you have kidney problems. You may need to take an oral solution instead of tablets so that the dose of your medication can be reduced exactly.

  • If you take more Lamivudine Normon than you should

It is unlikely that accidentally taking too much of your medication can cause serious problems. However, you should inform your doctor or pharmacist, or go to the emergency department of the nearest hospital for advice.

If you have taken more Lamivudine Normon than you should, consult your doctor, pharmacist, or call the Toxicology Information Service, phone 91 562 04 20, indicating the medication and the amount taken.

  • If you forget to take Lamivudine Normon

If you forget to take your medication, take it as soon as you remember and continue taking it as before. Do not take a double dose to make up for forgotten doses.

  • If you stop taking Lamivudine Normon

Do not stop taking Lamivudine Normon without consulting your doctor.
