Penciclovir
cold sores
"I too can attest the same thing every one has said.  It is the best cold sore medicine on the market.  It will cut the outbreak time to a few days, opposed to the 2-3 weeks.  Unfortunately, I was blown away this week at the retail cost of this prescription.  I have been using this medication for over 15 years and my insurance has always covered it.  The most being $40 for the small tube.  Now, my new insurance does not cover it, and I found the price at the pharmacy is charging is $795.  I cannot pay this price and the coupon on the internet only offers up to $45.  I feel screwed/gauged by this pharmaceutical company (New American Therapeutic) who purchased the rights to this medication in 2010 by Norvatis. No generic is available."
