☆ What types of interferon are there? What is the difference? The interferon currently used in clinical practice is a genetically engineered interferon, which is characterized by good safety, high purity, mass production and low price compared to the previous blood-borne interferon. According to its different sources, it is divided into α, β, γ. Among them, α, β interferon has strong immunomodulation and antiviral effects, and can be used to treat chronic hepatitis B and C; γ interferon is mainly used for anti-tumor. ☆ Doctors sometimes mention 5 million, 6 million interferon, what does this mean? 5 million, 6 million refers to the dose of interferon, that is, each injection contains 5 million units of interferon or 6 million units of interferon, just the dose is different. ☆ Is 6 million necessarily better than 5 million interferon? 6 million units is higher than 5 million units, the antiviral treatment effect is stronger, of course, its side effects are also correspondingly more. The exact dosage of interferon to be used is determined by the treating doctor according to the patient’s condition. ☆ Is there a big difference between domestic and imported interferon? The major difference between the two types of interferon is the difference in half-life. Domestic interferon has a shorter half-life of a few hours, while imported interferon has a longer half-life of 60-70 hours. Therefore, domestic interferon needs to be injected every other day, and imported interferon can be injected once a week.
