What is Aciclovir?
Aciclovir is an antivirus medication used in the treatment of a variety of conditions. It is a common cold sore treatment and is also used in the treatment of genital herpes and other viruses.

What is Aciclovir used to treat?
It is commonly prescribed to treat and prevent a recurring attack of herpes, e.g. cold sores and genital herpes. It can also be used to protect those who suffer from low immune systems from contracting the herpes virus. Although it is not possible for a medication to cure the herpes virus, Aciclovir works to slow the growth and spreading of the virus around your body. As a result of this, it will lesson your symptoms of the infection.
Doctors may also prescribe Aciclovir to treat shingles and chicken pox as they are also caused by the herpes virus, varicella zoster.
These tablets work by stopping the herpes virus from spreading, controlling the infection and allowing your body to fight back against the likes of cold sores and genital herpes.
No medicine can remove this virus from your system, but antiviral medication like Aciclovir can help to treat individual cases of the likes of cold sores and genital herpes.
Aciclovir or Valaciclovir, what is the difference?
