-Continued We all know that the liver is a human chemical factory, an important detoxification organ. Drugs, poisons and many chemicals are detoxified, transformed and metabolized here. Patients with liver disease often have impaired liver function, which is treated with drugs, naturally increasing the burden on the liver and in some cases even aggravating the damage to the liver. This creates a contradiction. Therefore, the doctor must: First, to seize the focus, to be symptomatic, to solve the main problem, not indiscriminate use of drugs, more drugs. Second, the drug to be used must not be harmful to the liver, at least no side effects of this drug on the liver have been found yet. Third, once the disease is cured, the drug should be stopped as soon as possible. At present, drugs for the treatment of hepatitis B, including antivirals and interferon, have side effects of varying degrees. In particular, interferon and adefovir have more pronounced adverse effects and deserve comprehensive consideration. Adefovir has also been found to cause serious damage to the kidneys! It should also be mentioned that some people who have liver disease seek medical help in a hurry and use all kinds of local remedies. As a result, the liver is severely damaged, almost taking their lives.
