Sorry for the delay, just saw this. I increased my dose to 20mg due to depression after my 8th week of treatment. I was fine until that time with the Prozac, 10 ml.
Seems to be working well.
Treatment is not has bad as I thought. Just having raspy voice, laryngitis problems!! Keeps me quiet!! :)
It sounds as if they have given you the Prozac as a prophalactic prior to treatment so it is quite likely that you wouldn't feel any benefit. I would be loathe to up the dose until after you have started treatment. It is common for the interferon to cause serotonin depletion and by starting the Prozac before the interferon whill hopefully offset any negative effects you might feel. I was on Prozac before I started and had to increase it after about 5 weeks of treatment.
All the best.
