Hepatitis B surface antigen will be higher on medication is due to a large number of new cells in the liver, which will gradually decline and stabilize in later stages.
If hepatitis B surface antigen exists, it needs to be combined with antiviral drugs such as entecavir for treatment. After the use of drugs, a large number of hepatitis B viruses are killed, and at this time, the normal function of the liver is gradually restored, and the hepatitis condition is alleviated, then a large number of new liver cells can appear.
At this time, the hepatitis B virus has not been completely eliminated, and the newborn hepatocytes are infected, which leads to the elevation of hepatitis B surface antigen. This kind of performance is usually transient, and with the subsequent treatment process, the surface antigen of hepatitis B will gradually decrease and stabilize.
Therefore, the increase of hepatitis B surface antigen caused by taking medicine is a normal manifestation, continue to adhere to the treatment.
