Valacyclovir treats conditions such as herpes virus infections, these include herpes labialis (a.k.a. cold sores), herpes zoster (a.k.a. shingles), and herpes simplex (a.k.a. genital herpes) in adults. The same treatment is also used for treating chickenpox and cold sores in children. Within the body, valacyclovir becomes the anti-herpes medicine, acyclovir. Valacyclovir can relieve pain and discomfort as well as help sores to heal faster. You may only get access to use Valacyclovir with a doctor's prescription.
