Viruderm is an ointment containing the active ingredient acyclovir. Acyclovir belongs to the group of medicines called antivirals, active against the herpes simplex virus.
It is indicated for the local relief of symptoms caused by cold sores (fever blisters), such as itching, stinging or tingling in adults and adolescents from 12 years of age.
A doctor should be consulted if it worsens or if it does not improve after 10 days.
how does Viruderm work?
Cold sores, or fever blisters, are caused by an infection by a virus called herpes simplex.
There is usually a first infection inside the mouth (usually in childhood) which may go unnoticed, but in the case of children it should be diagnosed by the doctor so as not to confuse it with teething disorders or other oral processes. After this first infection, the herpes simplex virus remains in the body without symptoms. The infection frequently presents new outbreaks, in other moments of life, which usually appear as a consequence of sunburns, colds, fever, emotions, anxiety, wounds in the mouth, menstruation, dental or surgical interventions, or allergies to some medication.
These outbreaks consist of a tingling or itching sensation on the lips followed by the appearance, after one or two days, of several small blisters which then evolve into an open sore on the lips, which eventually crusts over.
Until the scab appears, a sign that the lesion has healed, the blisters or sores are contagious.
