cold sores
"My husband used a Denavir sample, attained from our Dermatologist.  He did not begin use at onset but when he began Denavir, the 'cold sore' disappeared in half the normal time  - no side effects either. We were astounded.  Tried to get another sample -they didn't have anymore, but gave my husband an Rx for it.  Checked with Pharmacy - the cost for Denavir was exorbitant. It is great stuff."
