varicella-zoste
"At the age of 61 I had Shingles.  This medication helped with the pain as well as the blisters.  After only 3 or 4 days on Valtrex my blisters began diminishing.  I would estimate somewhere between 40 to 60 percent of the blisters were gone.  It is now day six and I am looking forward to a complete recovery soon."
