Peg interferon treatment

Please let me know about the interferon therapy please.
I have been taking antiviral tablets for last 5 years. My PVR is negative, HBeAg <10, HBsAg 4050, my LFT, RFT, ultrasound are perfectly fine.
Now my doctor is advising me to go for combination therapy to get rid of HBsAg. This combination will be with interferon. Should I go for it?
I am of 30 year male.
Thanks nd regards
