Taking this medicine

You should take one tablet three times a day for a total of five days.


If taken within five days of the start of an outbreak, Aciclovir should shorten your outbreak by one to two days and make the symptoms less severe. It might even prevent the outbreak if taken early enough. 

This medication is for acute outbreaks of genital herpes ONLY.

How to treat herpes

Aciclovir tablets are one of the most popular antiviral medications available for treating herpes.

How does herpes treatment work?

Aciclovir works to prevent the herpes virus from multiplying, which reduces the severity of the infection.

Herpes and pregnancy

If you have herpes and are pregnant, consult your GP. Don’t take any treatment without first seeking medical advice due to potential complications for you and your baby.

Herpes treatment duration

The duration of herpes treatment will depend on the frequency and severity of your outbreaks.

Aciclovir may be prescribed as a form of episodic treatment as an when outbreaks occur. If you have six or fewer outbreaks a year, you will most likely be prescribed this form of herpes treatment. This herpes treatment course usually lasts for five days.

Aciclovir can also be prescribed as a form of suppressive treatment, taken every day to reduce or even stop recurrences. A break from medication to re-assess your herpes is recommended every 6-12 months. 

Alternative treatments for herpes

A local anaesthetic gel like Instillagel can be used alongside Aciclovir to help reduce painful herpes outbreaks.

If you experience more than six outbreaks of genital herpes a year, consider taking herpes suppression therapy.

Alternatives to Aciclovir include Valacyclovir and Famciclovir, but we do not currently offer these through this service.
