What can i use instead of valtrex (valacyclovir) which is too expensive?

Time: The lesions will go away by themselves and will take only slightly longer if not treated. By the way, the medicine you refer to makes the lesions only slightly less painful (if any at all) than no treatment at all.

Acyclovir.: Acyclovir is an earlier-generation antiviral medication that is available as a generic. The dosage is not the same as valtrex, (valacyclovir) and taking it is a bit more cumbersome, usually requiring three to four times a day dosing; but it is an effective alternative that is considerably less expensive.
