What is Aciclovir and how does it treat cold sores?
Aciclovir is an antiviral medication used to treat the herpes simplex virus and other closely related viruses, such as chicken pox or shingles. It helps stop the spread of the herpes virus in the body by interrupting the process of virus replication which reduces the duration of the infection. It is not a cure for these infections, as the virus continues to live in the body even after an outbreak but Aciclovir reduces the severity and length of the outbreak. Instead of an infecrtion lasting 10 days it can often cut the time in half and reducing the pain endured.
