1. What ENTECAVIR DOC is and what it is used for

ENTECAVIR DOC tablets are an antiviral medicine, used in adults for the treatment of chronic (long-term)
hepatitis B virus infection. ENTECAVIR DOC can be used in patients whose liver is damaged but still functions properly (compensated liver disease) and in patients whose liver is damaged and does not function properly (decompensated liver disease).
ENTECAVIR DOC tablets are also used for the treatment of chronic (long-term) hepatitis B virus infection
in children and adolescents from 2 to 18 years of age. ENTECAVIR DOC can be used in children whose liver is damaged but still functions properly (compensated liver disease).
Hepatitis B virus infection can cause liver damage. ENTECAVIR DOC reduces the amount of virus in the body and improves liver condition.

2. What you need to know before taking ENTECAVIR DOC

  • if you are allergic (hypersensitive) 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 taking ENTECAVIR DOC

  • if you have had kidney problems – inform your doctor. This is important because ENTECAVIR DOC is eliminated from the body through the kidneys, and you may require a dose adjustment or different dosing schedule.
  • do not stop taking ENTECAVIR DOC without medical advice, as hepatitis may worsen after stopping treatment. If treatment with ENTECAVIR DOC is discontinued, your doctor will continue to monitor you and perform blood tests for several months.
  • discuss with your doctor whether your liver is functioning properly, and, if not, how this may affect your treatment with ENTECAVIR DOC.
  • if you are also infected with HIV (human immunodeficiency virus), inform your doctor. You must not take ENTECAVIR DOC to treat hepatitis B infection unless you are already receiving medications for HIV, as the effectiveness of future HIV treatment may be reduced. ENTECAVIR DOC will not control your HIV infection.
  • taking ENTECAVIR DOC 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 to take precautions to avoid spreading the hepatitis B virus (HBV) to others. A vaccine is available to protect individuals at risk of contracting hepatitis B virus (HBV) infection.
  • ENTECAVIR DOC belongs to a class of medicines that can cause lactic acidosis (excess lactic acid in the blood) and enlargement of the liver. Symptoms such as nausea, vomiting, and stomach pain may 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 significantly overweight. Your doctor will monitor you regularly during treatment with ENTECAVIR DOC.
  • if you have previously received treatment for chronic hepatitis B, inform your doctor.
