Therefore, it is important that you take appropriate precautions to prevent others from becoming infected with HBV. There is a vaccine to protect people at risk of HBV infection.
- Entecavir Normon 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 stomach pain could indicate the development of lactic acidosis. On rare occasions, this serious side effect has been fatal. Lactic acidosis occurs more frequently in women, especially in those who are overweight. Your doctor will monitor you periodically while you are taking entecavir.

If your liver disease is very advanced, your doctor will also instruct you on taking entecavir on an empty stomach.
An empty stomach means at least 2 hours after and 2 hours before the next meal.
