About Valtrex

What is Valtrex?

Valtrex is a branded tablet which contains the active ingredient (medication) valaciclovir. Valtrex can be used for outbreaks of HSV infections, including genital herpes and cold sores.

What are Valtrex tablets?

Valtrex tablets are white, oval shaped tablets that contain valaciclovir. The tablets should be taken by mouth and are prescribed by a doctor. Valtrex is the branded name but you may also find valaciclovir tablets under other names.

What are Valtrex tablets used for?

Valtrex can be used in the treatment of:

cold sores
shingles
genital herpes
chicken pox

Superdrug offers generic valaciclovir only for the treatment of genital herpes and cold sores. Both of these infections are caused by the virus HSV. Valtrex can be used to treat the first outbreak, further outbreaks, and can be used between any outbreaks, as a suppression treatment. There is no cure for HSV, but Valtrex can help with outbreaks of cold sores or genital herpes.

What’s the difference between Zovirax and Valtrex?

Zovirax is a branded tablet containing the medication aciclovir. Valtrex is a branded tablet containing the medication valaciclovir. These medications work in similar ways, as the medication valaciclovir is broken down inside your body and becomes aciclovir. Both medications can be used to treat outbreaks of HSV and are equally effective. The only difference is that you take fewer Valtrex tablets in one day than you do with Zovirax.

How does Valtrex work?

Valtrex works by preventing the herpes virus from growing and multiplying, reducing its ability to spread to healthy cells. This helps the body to control the virus and suppress an outbreak, reducing symptoms such as itching, pain, and tingling. It can also help sores heal up faster.

Valtrex can also help to reduce the risk of transmission of herpes. Studies have shown that those taking valaciclovir were 50% less likely to transfer the virus to their partner than those who were not taking it.

While Valtrex can help to reduce the symptoms of herpes, it’s important to note Valtrex is not a cure for herpes.

How long does it take Valtrex to work?

For most outbreaks of HSV, you should start to feel better within a few days of taking Valtrex tablets. If you do not feel better after your tablets are finished, or your symptoms get worse whilst taking them, speak with your doctor. You may need a different medication or a higher dosage. Never increase your dosage without speaking to a doctor first.

How long does a herpes outbreak last with Valtrex?

Herpes outbreaks can last around 7 to 14 days, with symptoms lasting 7 days or more without treatment. The first outbreak of HSV may last longer. If you take Valtrex when you see the first signs of an outbreak, it should help you to feel better within a few days.

How effective is Valtrex?

One study found that treatment with valaciclovir can decrease the number of outbreaks and the length of outbreaks by 91% to 97%. This means it is very effective and is one of the most prescribed medications for HSV infections.

Can I have sex while taking Valtrex?

If you have been prescribed Valtrex for genital herpes, you must not have sex until all sores and blisters have fully healed. You should always try to use a condom with your partner, even after the sores have gone. This reduces the chance of your partner catching HSV.

If you have been prescribed Valtrex for cold sores, you should avoid kissing or oral sex until the cold sores have fully healed. This means you could still have sex, as long as you avoid this.

How to use Valtrex

Take Valtrex as soon as you first notice signs of an outbreak, as this is when it is most effective.

These symptoms include:

redness or lumps under the skin
itching
tingling
burning
sores or blisters forming

The dosage will depend on why you are using Valtrex. You can be prescribed Valtrex 1 to 4 times daily, with doses of 500mg to 2000mg. Your doctor will tell you what doses you need and your dosage will also be printed on your tablet pack.

How to take Valtrex tablets

You can take Valtrex tablets by mouth, with a full glass of water. Taking a full glass of water helps to keep the kidneys to break down this medication and continue to work normally. You can take the tablet with or without food.

Valtrex can be taken in 3 ways:

Valtrex can be used to suppress herpes when prescribed 500mg to 1000mg daily.
Valtrex can be used to prevent HSV outbreaks. The typical dosage to prevent the outbreak is 500mg, 2 times daily for 3 days. You should take Valtrex as soon as you notice the first symptoms.
Valtrex can be used for cold sore suppression when taken daily, for up to a year. This can reduce the chances of your cold sore outbreaks by a third.

When should I take Valtrex?

Valtrex should be taken as soon as you see the first symptoms appear. If it is your first outbreak, use Valtrex as soon as you’ve spoken to a doctor and been prescribed the treatment. It can be taken any time, as long as doses are spread evenly throughout the day.

How many Valtrex tablets should I take?

The number of tablets you take will depend on what you have been prescribed and whether you are using Valtrex for suppression or treatment of an outbreak. To treat an outbreak you should take 4 a day.

Valtrex doses

There are different Valtrex doses depending on whether you are using it for the treatment of genital herpes, cold sores, or as a suppression treatment. The general treatment for HSV outbreaks starts at 500mg Valtrex tablets, 1 to 4 times daily, for around 5 days and can be increased if needed, but never increase your dose until you have spoken to a doctor.

Valtrex 500mg

Valtrex tablets are 500mg tablets that are usually taken twice daily. For recurrent outbreaks, Valtrex 500mg tablets can be taken for 3 to 5 days, 2 times a day. The first outbreak of HSV lasts the longest and treatment will be 500mg tablets, 2 times a day, for up to 10 days during this time.To prevent outbreaks, Valtrex 500mg tablets can also be taken once daily.

Valtrex 1000mg

Valtrex can also be found in 1000mg tablets. This is for the treatment of cold sores and is taken twice daily. For this treatment, you will only take 2 doses, in 1 day.
