Cold Sores (Herpes Simplex): Here are some other options.
Valaciclovir is a medication you can take to help stop the symptoms of cold sores and genital herpes. The virus that causes these skin conditions is known as herpes simplex, and one of its main effects is that it causes blisters on the skin. These can make you feel self-conscious, but there are treatments available to help you.
Taking Valaciclovir when you first get symptoms means that you can tackle the virus and ensure that any discomfort is minimised.
Valaciclovir is the generic name for a branded medication called Valtrex, and it’s also the name of the main active ingredient in the medication. Both tablets do exactly the same job. Because it’s a generic treatment, Valaciclovir is usually cheaper than Valtrex.
Valaciclovir stops the enzymes that the herpes simplex virus creates from multiplying, and reduces the severity of your outbreak. It stops the infection from spreading too. It works best if you take it as soon as you notice any symptoms surfacing.
There’s only one standard dose of Valaciclovir and that’s 500mg. You may take different amounts of tablets depending on whether you’re being treated for cold sores or genital herpes.
If you’ve got any questions about the dose, or find it’s not working for you, we’ll be happy to talk to you about alternative treatments.

Always take Valaciclovir as directed by our clinician.
Take your tablets with a drink of water. They can be taken with or without food. If you miss a dose, it’s really important that you don’t take an extra one to make up for it. Simply take your next dose at the right time and then carry on as normal.
Treatment time for the symptoms of cold sores and genital herpes can vary from person to person, and depends on how severe your infection is. Catching the outbreak at the first stages and starting treatment as soon as possible helps to get it under control quicker.
Once you start treatment, it should become effective within five days. If you think the treatment isn’t working as well as it should then you should send our clinician a message, and they can give you advice on the next steps.
If you miss a dose then take it as soon as you remember, and then carry on as normal. Don’t take two doses at once to make up for a missed tablet.
Don’t take more than the prescribed dose. If you’ve taken too much Valaciclovir by accident then you should go to hospital and take the medication packet with you.
