I had a week course of Famvir when I was diagnosed with shingles. Haven't had any outbreaks since.  

I noticed an improvement in my condition almost as soon as I started taking this medicine.  

This antiviral medication is very effective. I was prescribed a different drug during my first herpes outbreak, and it didn't really help as I suffered two recurrent outbreaks after the treatment. So I tried Famvir for my third outbreak and I finally felt completely recovered! Almost a year has passed - no outbreaks any more.
