How does interferon treat chronic hepatitis B?
Interferon alfa (Intron A, Roferon A, Sylatron) gives your immune system a boost. You take it as a shot for at least 6 months. It doesn’t cure the disease. It treats liver inflammation. Long-acting interferon, peginterferon alfa2a (Pegasys, Pegasys Proclick) can also help. This drug does have side effects. It can make you feel bad all over, depressed, and zap your appetite. It also lowers your white blood cell count, which makes it harder to fight off infection.
