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.
