Hello dear ,
I evaluated your concern deeply .
@ Valacyclovir is anti-viral drug used as main stay management of 
herpes       lesions & other viral infections .
@ I strongly recommend to apply 
Calamine lotion 3 times a day with
    excellent  outputs.
# prophylactic dose of 
fluconazole (150)mg once at night for 2 days
