1. What Entecavir Dr. Reddys is and what it is used for

Entecavir is an antiviral medicine used to treat chronic (long-term) hepatitis B virus (HBV) infection in adults.

Entecavir may be used in patients whose liver is damaged but still functions adequately (compensated liver disease) and in patients whose liver is damaged and does not function adequately (decompensated liver disease).

Entecavir is also used to treat chronic (long-term) HBV infection in children and adolescents from 2 to less than 18 years of age.

Entecavir may be used in children whose liver is damaged but still functions adequately (compensated liver disease).

Hepatitis B virus infection can damage the liver. Entecavir reduces the amount of virus in the body and improves the condition of the liver.

2. What you need to know before starting to take Entecavir Dr. Reddys

Do not take Entecavir Dr. Reddys

• if you are allergic to entecavir or to any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor or pharmacist before starting entecavir

• if you have ever had kidney problems, inform your doctor. This is important because entecavir is eliminated from the body through the kidneys, and your dose or treatment schedule may need to be adjusted.

• do not stop taking entecavir without consulting your doctor, as your hepatitis may worsen if treatment is interrupted. When your treatment with entecavir is stopped, your doctor will continue to monitor you and perform blood tests for several months.

• ask your doctor whether your liver is functioning properly, and if not, about the potential effects your treatment with entecavir might have.

• if you are also infected with HIV (human immunodeficiency virus), make sure to inform your doctor. You should not take entecavir for the treatment of your hepatitis B infection unless you are also taking medications for the treatment of HIV infection, because otherwise the effectiveness of future HIV treatments could be reduced. Entecavir will not control your HIV infection.

• taking Entecavir will not prevent you from transmitting the hepatitis B virus (HBV) to others through sexual contact or bodily fluids (including blood contamination). Therefore, it is important that you take appropriate precautions to prevent others from becoming infected with HBV. A vaccine is available to protect individuals at risk of HBV infection.

• entecavir belongs to a class of medicines that can cause lactic acidosis (excess lactic acid in your blood) and enlargement of the liver. Symptoms such as nausea, vomiting, and stomach pain could indicate the development of lactic acidosis. This rare but serious side effect has occasionally been fatal. Lactic acidosis occurs more frequently in women, especially those who are overweight. Your doctor will monitor you periodically while you are taking this medicine.

• if you have previously received treatment for chronic hepatitis B, please inform your doctor.

Children and adolescents

Entecavir must not be used in children under 2 years of age or weighing less than 10 kg.

Taking Entecavir Dr. Reddys with other medicines

Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.

Taking Entecavir Dr. Reddys with food and drinks

In most cases, you may take entecavir with or without food. However, if you have previously been treated with another medicine containing lamivudine as the active substance, consider the following. If you have switched to entecavir because lamivudine treatment was not successful, you must take entecavir on an empty stomach, once daily. If your liver disease is very advanced, your doctor will also instruct you to take entecavir on an empty stomach.

An empty stomach means at least 2 hours after and 2 hours before the next meal.

Children and adolescents (from 2 to less than 18 years of age) may take entecavir with or without food.

Pregnancy, breastfeeding, and fertility

Inform your doctor if you are pregnant or intend to become pregnant. The use of entecavir during pregnancy has not been shown to be safe. Entecavir should not be used during pregnancy except when clearly necessary, as determined by your doctor. It is important that women of childbearing potential who are being treated with entecavir use an effective method of contraception to prevent pregnancy.

You must not breastfeed during treatment with entecavir. If you are currently breastfeeding, inform your doctor. It is unknown whether entecavir, the active substance of this medicine, is excreted in human breast milk.

Driving and using machines

Dizziness, tiredness (fatigue), and drowsiness (somnolence) are common adverse reactions that could affect your ability to drive and use machines. If you have any doubts, consult your doctor.

Entecavir Dr. Reddys contains lactose

If your doctor has diagnosed you with an intolerance to certain sugars, consult him before taking this medicine.

3. How to take Entecavir Dr. Reddys

Not all patients need to take the same dose of entecavir.

Always follow exactly the instructions provided by your doctor for taking this medicine. If you are unsure, consult your doctor or pharmacist again.

For adults, the recommended dose is 0.5 mg or 1 mg once daily (orally).

Your dose will depend on:

• whether you have previously been treated for HBV infection, and which medication you received.
• whether you have kidney problems. Your doctor may prescribe a lower dose or advise you to take it less frequently than once daily.
• the condition of your liver.

For children and adolescents (aged 2 to less than 18 years), your pediatrician will determine the appropriate dose based on the child's body weight. Children weighing at least 32.6 kg may take the oral solution or the 0.5 mg tablets. Entecavir oral solution is recommended for patients weighing between 10 kg and 32.5 kg. All doses should be taken once daily (orally). There are no recommendations for the use of entecavir in children under 2 years of age or weighing less than 10 kg.

Your doctor will advise you on the correct dose for you. Always take the dose recommended by your doctor to ensure the medicine is fully effective and to reduce the risk of developing treatment resistance. Take entecavir for the entire duration prescribed by your doctor. Your doctor will tell you when to stop treatment.

Some patients should take entecavir on an empty stomach (see Entecavir Dr. Reddys with food and drink in Section 2). If your doctor instructs you to take entecavir on an empty stomach, this means at least 2 hours after a meal and 2 hours before the next meal.

If it is almost time for your next dose, do not take the missed dose. Wait and take the next dose at the usual time. Do not take a double dose to make up for missed doses.

Do not stop treatment with Entecavir Dr. Reddys without consulting your doctor
