Interferon can inhibit the replication of hepatitis B virus and reduce the number of hepatitis B virus, so interferon plays a very important role in hepatitis B treatment. Interferon has the effect of inhibiting the replication of hepatitis B virus, improving liver function, reducing inflammatory and fibrotic lesions in liver tissue, and reducing and preventing the occurrence of cirrhosis and hepatocellular carcinoma. However, for patients with chronic hepatitis B who have obvious liver function impairment, such as serum bilirubin greater than twice the upper limit of normal value or ghrelin greater than ten times the upper limit of normal value, liver function should be improved before using interferon therapy. It should be noted that pregnant women and cardiac insufficiency prohibit the use of interferon, in addition, if used for a long period of time may form some myelosuppression, loss of appetite and other adverse reactions. You can stop using it under the guidance of professional physicians, and in the process of using it, you need to check it regularly, and then adjust the medication according to the results.
