1, how to choose antiviral drugs: Hepatitis B patients need to carefully choose antiviral drugs, once the antiviral can not just stop and replace, otherwise it will cause viral rebound, which will lead to fulminant liver failure or severe hepatitis, be sure to follow medical advice on medication. Those with ALT > twice the upper limit of normal and viral load (HBV-DNA) > 1*10^5/L, or those with liver cancer or cirrhosis and elevated viral load (1*10^3/L < HBV-DNA < 1*10^5/L), and those with ALT < twice the upper limit of normal, need antiviral therapy and are recommended to take nucleoside antivirals such as Lamivudine, adefovir, entecavir and telbivudine are recommended. Lamivudine is fast and cheap, 500+/month, but after 6-8 months of use, some patients will develop resistance and virus mutation; adefovir is often used as a combination antiviral after lamivudine resistance; entecavir is fast and expensive, 1000+/month, and generally does not cause virus resistance and mutation; telbivudine is fast and moderately priced, 600+/month, and generally does not cause virus resistance and mutation. It does not cause virus resistance and mutation. You can choose the drug depending on your economic situation. 2, pay attention to life conditioning: avoid spicy and stimulating, greasy diet, quit smoking and alcohol, do not stay up late, smooth the mood. Try not to take drugs that damage liver function. You can engage in the work that you can do, do not strain.
