Herpes Simplex, Mucocutaneous/Immunocompromised Host
"It&#039;s well worth it to ask your doctor to prescribe 1gm daily Valtrex for recurring cold sores.  You can easily take from your daily prescribed to help immediately when you notice a cold sore start by then taking 1gm 3 times in 24 hours.  The prescription for 3 pills costs the same as 30 days so I recommend to talk to your doctor."
