She prescribed Valtrex, which is very expensive and did not help me at all. A physician I recently saw prescribed Famciclovir
, which is much less expensive and works much better. Knowing that I would have to take this for the rest of my life, I was worried that it would be dangerous with long term used and searched for something other than medication. On the Web, I discovered L-Lysine. I have been taking it for about 2 months and have not had an outbreak.
