More information
"Valtrex is a widely prescribed antiviral treatment used to manage the symptoms of herpes simplex and varicella zoster infections. It is highly effective at reducing the severity of outbreaks like shingles or cold sores when taken at the first sign of symptoms, such as tingling or burning. By converting into aciclovir within the body, it achieves higher absorption levels, allowing for a more convenient dosing schedule than many traditional alternatives."

Valtrex is a branded antiviral medicine used primarily to treat infections caused by the herpes simplex virus (HSV) and the varicella zoster virus (VZV). It is commonly prescribed for the treatment of shingles in adults, cold sores in adolescents and adults, and both the treatment and suppression of genital herpes outbreaks.
The active ingredient in Valtrex is valaciclovir (as valaciclovir hydrochloride), which is known as a "prodrug" because it converts into aciclovir once it enters the bloodstream. This conversion process is what allows the body to absorb the medicine more efficiently, leading to better results with fewer doses.
Many users report that Valtrex is highly effective at stopping a cold sore or herpes outbreak from fully developing if taken during the "prodromal" phase (the initial tingling sensation). Patients often prefer it over generic aciclovir because the reduced frequency of doses makes it easier to complete the full course of treatment.
You should always read the Patient Information Leaflet (PIL) included in your medication pack for a comprehensive guide on usage and safety. The PIL contains essential data regarding ingredients, storage instructions, and a full list of potential side effects as reported by the manufacturer.
Valtrex works by interfering with the way the virus replicates its DNA, effectively stopping the infection from spreading to healthy cells. By inhibiting viral reproduction, the medication helps the body's natural immune system to clear the current outbreak faster and reduces the associated pain and discomfort.
You should swallow Valtrex tablets whole with a glass of water, and it is important to stay well-hydrated throughout your course of treatment to support kidney function. The tablets can be taken with or without food, but you should aim to space your doses as evenly as possible throughout the day.
The dosage for Valtrex depends entirely on the condition being treated and whether it is a first-time or recurrent infection.
| Condition | Typical Dosage Guidance |
|---|---|
| Shingles | 1000mg taken three times daily for 7 days. |
| Cold Sores | 2000mg taken twice for one day only (12 hours apart). |
| Genital Herpes (Outbreak) | 500mg taken twice daily for 3 to 5 days. |
| Suppression Therapy | 500mg taken once daily to prevent recurrences. |
Like all medicines, Valtrex can cause side effects, although not everybody gets them, with the most common being mild and temporary. Common side effects reported by UK patients include:
- Headaches
- Nausea or feeling sick
- Dizziness
- Diarrhoea
- Sensitivity to sunlight (photosensitivity)
You must inform your prescriber if you have a history of kidney disease or liver problems, as your dosage may need to be adjusted to ensure your safety. Elderly patients and those with weakened immune systems should be monitored closely, and it is vital to drink plenty of fluids while taking this medication to prevent dehydration.
Valtrex is often compared to aciclovir and famciclovir, which are other common antiviral treatments used for similar conditions in the UK.
- Valtrex vs Aciclovir: Valtrex has higher bioavailability, meaning it is absorbed better and usually requires only 2 doses a day compared to 5 doses for aciclovir.
- Valtrex vs Famciclovir: Both are effective for shingles and herpes, but Valtrex is more frequently used for the specific "one-day" treatment of cold sores.
Can I take Valtrex while pregnant?
You should consult your doctor before taking Valtrex if you are pregnant or breastfeeding, as they will need to weigh the benefits of treatment against any potential risks to the baby.
Does Valtrex cure herpes?
No, there is currently no cure for the herpes simplex virus. Valtrex helps manage the symptoms and reduces the frequency and severity of outbreaks.
When should I start taking the tablets?
For the best results, you should start taking Valtrex as soon as you notice the first signs of an outbreak, such as itching, tingling, or redness, before blisters appear.
