My experience (48 weeks of treatment) was that side effects varied, some would come and go, others were with me throughout. The worst for me was the hemolytic anemia
. I had to have a transfusion at week 6 and
took the rescue drug, Procrit, for 40 weeks. The anemia causes exhaustion, dizzyness and extreme shortness of breath. The good news is that the anemia indicates that your ribavarin dose is not too low.
