Interferon can be used in the early stage of cirrhosis caused by hepatitis B virus, but it is not recommended for patients with obvious cirrhosis or cirrhotic ascites and cirrhosis not caused by hepatitis B virus. Interferon has an obvious antiviral effect, through interferon on the cell surface to produce white blood cells to prevent the replication of hepatitis B virus, so if the hepatitis B virus caused by cirrhosis patients in the early stage can use interferon. However, it is not recommended to use interferon in patients with cirrhosis, cirrhosis ascites and other obvious abnormalities of liver function, non-hepatitis B virus and other causes of cirrhosis, which may induce severe hepatitis, liver failure and other phenomena. Therefore, these patients need to use interferon under the guidance of a doctor after the liver function and blood routine and other indicators reach the standard. Patients with early cirrhosis should also use interferon cautiously, and it is recommended to start with a small dose, and if there is any discomfort in the process of using interferon, it is necessary to consult a doctor in time to avoid delaying the condition.
