My husband did daily dose (15 mcg's) of Infergen for 6 months and then every other day for the remainder of his 48 week treatment. He also took Procrit, though I'm not sure of the amount, but it was 2 shots per week. It has been just over 1 year since he stopped treatment and he still has serious sides. His fatigue is still debilitating, muscle weakness, vision problems and still has ringing in his ears.
I only did 13 weeks, am now off tx for the past 7 weeks - I still do not feel up to snuff. Supposedly riba stays in your system for up to 6 months, and in any event you're recovering from a sustained dose of poison that's compromised your immune system. From what I've read, a return to "norrmal" can take a long while and may never be complete. Another point is that most of us are middle-aged, and some of the bodily changes we experience might just be part of the aging process. The best thing anybody can do is get enough exercise - all kinds: aerobic, resistance training, and stretching.
