During hepatitis B treatment, liver protection is needed if liver function is impaired, but not if liver function is normal. During hepatitis B treatment, antiviral medications such as lamivudine tablets, adefovir tablets, and entecavir tablets are taken under a doctor’s supervision for treatment. This is only used to treat viral replication. If liver function is impaired, liver protection therapy, such as polyene phosphatidylcholine, is needed and can help restore liver function. However, if liver function returns to normal, liver protection therapy is not needed. If liver protection will increase the burden on the liver and even lead to serious liver function damage. Whether liver preservation is possible during the treatment of hepatitis B virus, it is recommended that the patient is under the guidance of the doctor.
