Hepatitis B drugs are mainly anti-hepatitis B virus drugs, and there are two types of oral drugs and injectable drugs. There are six oral drugs, namely lamivudine, adefovir, telbivudine, entecavir, tenofovir and propofol tenofovir, the latter three being the first-line drugs currently used orally, with prices ranging from 10-500 per month. Injectable therapies are divided into regular interferon therapy and pegylated interferon therapy. Currently, pegylated interferon, also known as long-acting interferon therapy, is generally used, and it is relatively expensive, costing about 40-50,000 yuan for a 48-week course of treatment. Therefore, the price of hepatitis B medication is not consistent for different therapies.
