Interferon for HPV infection is $40/box for domestic 3 million units, $200/box for 5 million units, and $1,000/box for imported 180μg. Interferon, also known as synthetic glycoprotein, has the function of anti-virus, inhibiting cell proliferation and boosting immunity. There are two types of interferon for treating HPV infection: imported and domestic, and the specifications are also different, so the selling price will be somewhat different. Generally, the price of domestic interferon with 3 million units is 40 yuan per box, while the price of 5 million units is 200 yuan per box. Imported interferon costs more, plus tariffs, so the cost will be higher, 180 μg priced up to 1,000 yuan a box, depending on the level of hospitals, purchase channels and so on.
