The price of interferon cannot be generalized and varies according to the level of the hospital and the size of the city. For third-tier class A hospitals and provincial capitals, the price of one interferon is between 178.9 and 198.6 yuan. For second-tier cities and second-tier A and third-tier B hospitals, the price per interferon is in the range of 158.6-172.9 RMB. In third-tier cities and third-level C hospitals, the price per interferon is relatively the cheapest at 127.8-132.7 yuan, but there is a slight difference in the price of interferon because of the different manufacturers that have to produce it and the different number of milliliters per bottle of packaging.
