Cold Sores
"Had cold sores on lips &amp; nose regularly since childhood.  But not in the 10 or more years that I&#039;ve had a Denavir prescription.  In that time, if I apply at the first tingle, it rarely ever breaks through to become a sore.  It has been a blessing.  The cost is ridiculous.  $700 plus, with a ~$175 insurance co-pay usually.  Almost fainted last time I refilled, as CVS listed a $135 coupon on the receipt, so I wound up paying only $20.  Do not know what that was about (asked no questions).  I skipped out of the pharmacy quickly and enjoyed my surprise Christmas present!"
