Warnings and precautions

Consult your doctor or pharmacist before starting to take entecavir

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

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

• ask your doctor if your liver is functioning properlyand if not, about the possible effects that your treatment with entecavir could have.

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

• taking entecavir will not prevent you from infecting others with the hepatitis B virus (HBV)through sexual contact or bodily fluids (including blood contamination). Therefore, it is essential to take the necessary precautions to prevent others from becoming infected with HBV. There is a vaccine to protect individuals at risk of HBV infection.

• Entecavir belongs to a class of medicines that can cause lactic acidosis(excess of lactic acid in your blood) and liver enlargement. Symptoms such as nausea, vomiting, and abdominal pain may indicate the development of lactic acidosis. In some cases, this rare but severe side effect has 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 received previous treatment for chronic hepatitis B, please inform your doctor.
