Hepatitis B core antibody positive should be timely and complete the examination. If you have been infected with hepatitis B in the past, there is no need for treatment; if you are infected with hepatitis B, you need general treatment and drug treatment. 1. General treatment: If the symptoms are obvious or the condition is serious, bed rest should be paid attention to. Eat high protein and high fiber food, which is good for liver repair. 2. Drug treatment: including hepatoprotective drugs and antiviral drugs. (1) Hepatoprotective drugs: such as glycyrrhizic acid preparation, silymarin preparation, bisabolol and so on. (2) Antiviral drugs: only used for chronic hepatitis B patients. Interferon and nucleoside analogs such as entecavir can be used. If it develops into severe hepatitis, it should be treated aggressively to prevent complications and immunomodulation, and strive for liver transplantation treatment at an appropriate period. In case of hepatitis B core antibody positive, other HBV antigen antibodies should be examined to clarify whether hepatitis B is present or not, and timely treatment should be carried out. The medication should follow the doctor’s prescription, and should not be used arbitrarily by oneself.
