What is Aciclovir?

Aciclovir is one of the most commonly used antiviral drugs that you can buy online to treat herpes virus. Aciclovir tablets provide effective treatment for outbreaks of the herpes virus including genital herpes, chicken pox, cold sores and shingles, so that you can effectively manage your condition. This highly effective medication works by preventing viruses from multiplying, and this reduces the severity of the infection, stopping it from spreading.

Taking this treatment within 24 hours after the first signs of an outbreak could help speed up recovery time from cold sores and genital herpes and stop the spread of the shingles rash around the body, as well as alleviating any symptoms.

How does Aciclovir work?

This medication works by stopping the spread of the viral cells by inhibiting enzymes instrumental in their spread. This allows your body to attack the virus more effectively in order to push it back into an inactive state. Therefore, taking Aciclovir as soon as possible can greatly improve recovery time, as the virus wouldn't have had time to progress far enough.

How to take Aciclovir?

Aciclovir should be taken in different doses dependent on whether you are using it for the treatment genital herpes, cold sores or shingles.

  • Treating shingles – an 800mg dose of Aciclovir five times a day over the course of seven days
  • Treating genital herpes and cold sores – a 200mg dose five times a day for five days
  • Preventing genital herpes and cold sores - a 200mg dose four times a day for six months to a year.
  • Each of these dosages can be taken with or without food and should be take with a drink of water.
  • If you miss a dose close to its scheduled time you can take it as soon as you remember. However, if it's close to the time of your next dose you should miss it completely. It is important that two tablets are never taken at the same time.


The two dosages of Aciclovir that are currently available to buy from OnlineClinic are 200mg and 800mg. The dosage you take is dependent on whether you're using the medication to treat shingles, cold sores or genital herpes. See the 'How to use Aciclovir?' section above for more information.
