What is Aciclovir?
Aciclovir (Acyclovir) is an antiviral medication used to treat or suppress infections caused by the herpes simplex virus. The antiviral tablets prevent the virus from multiplying, allowing the immune system to effectively suppress the herpes infection over the course of treatment.
Aciclovir is also used in the treatment of other viral infections such as cold sores, chickenpox and shingles (varicella-zoster virus). Our service can prescribe Aciclovir tablets for genital herpes only, for other conditions, visit your GP.
Acyclovir is the same medicine but with a different spelling, usually used by people from the United States.
How does Aciclovir work?
Aciclovir tablets work by targeting the virus when it tries to multiply. It blocks the viruses ability to grow its DNA successfully preventing it from producing more of itself. This greatly reduces the viral load on the body, allowing the immune system to get the upper hand on the herpes infection, treating or suppressing it.
What is genital herpes?
Genital herpes is a viral infection that can cause blisters to appear on the genitals. These are often painful sores that come and go. They will often weep fluids that may infect others through skin to skin contact during sexual intercourse. It is a lifelong infection with no known cure.
Antiviral treatments can be effective at suppressing the infection when an outbreak occurs or preventing the majority of outbreaks however, it will not clear the condition completely from the body. As the infection can be passed to others when outbreaks occur, it is best to refrain from sex during this time and/ or always use barrier protection during intercourse.
Aciclovir 400mg dose
To treat genital herpes in adults, Aciclovir should be taken three times daily. It is important to drink plenty of fluids (preferably water) when taking a course of these antivirals to minimise potential side effects.
If Aciclovir is being used to suppress an outbreak, the dosage is one tablet twice daily. Suppression treatment is used in people who have frequently recurring outbreaks of herpes. This is generally defined as more than 6 outbreaks per year.
The prophylactic treatment can help reduce, or completely stop recurring outbreaks. In addition, future outbreaks generally don't last as long and are less aggressive.

All of the main treatments for genital herpes are anti-virals which work in the same way. The main point of difference is that while Aciclovir needs to be taken three times daily, Valaciclovir and Famciclovir require twice-daily dosage. This makes taking the other treatments slightly easier for those who may struggle to remember the midday dose of Aciclovir.
Aciclovir is, however, the most cost-effective option, as both of the other antivirals are more expensive.
