Hi @Karin,
Yes, there have been a few studies to see if this is possible for people who have taken antivirals for many years. However, there are a few people for whom this is very dangerous and it can lead to severe liver damage because the virus comes back so quickly. It is very important to do this with very close monitoring from your doctor.
I just want to stress how important it is for people not to stop antiviral medications on their own without their doctor’s advice.
