Zovirax Cream Information
How does it work?
This cream contains the active ingredient aciclovir, which is an antiviral medicine. It is used to treat skin infections with the herpes simplex virus, for example cold sores and genital herpes (caused by herpes simplex virus types 1 and 2).
Aciclovir works by stopping the herpes simplex virus from reproducing and infecting more cells.
Aciclovir is converted to a more active form inside cells of the body that are infected with herpes simplex. The activated aciclovir then works by blocking the action of a viral enzyme called DNA polymerase.
The herpes virus needs the DNA polymerase enzyme to copy its genetic material from RNA to DNA. This process is necessary for the virus to multiply and continue to survive. By blocking the action of DNA polymerase, aciclovir prevents the herpes virus from multiplying. This controls the infection and helps the immune system to deal with it.
For recurrent infections aciclovir cream is most effective if treatment is started as soon as the first signs of the infection begin to reappear.
What is it used for?
Genital herpes (herpes simplex infection)
Herpes simplex infections of the skin, eg cold sores
