Overview

Valtrex is the trusted branded antiviral for genital herpes — designed to ease outbreaks quickly, reduce pain, and lower the risk of transmission with the convenience of just twice-daily dosing.

Known worldwide for its reliability and effectiveness, Valtrex contains valaciclovir, which stops the herpes virus multiplying and helps blisters heal faster. For patients who want the reassurance of a well-recognised brand, Valtrex offers both peace of mind and proven clinical results.

This medicine requires a secure online consultation with a UK-registered prescriber, and will only be supplied if clinically appropriate.


What is Valtrex


Valtrex is the branded version of valaciclovir — a trusted antiviral treatment for genital herpes. Once inside the body, it converts into aciclovir, which stops the herpes virus from multiplying. This helps control outbreaks, reduce painful symptoms, and speed up healing.

Valtrex is commonly prescribed to:

  • Shorten the length and severity of active herpes outbreaks
  • Relieve symptoms like burning, itching, and soreness
  • Promote faster healing of blisters and sores
  • Prevent future flare-ups when taken daily as suppressive therap


With convenient twice-daily dosing, Valtrex offers reliable and clinically proven protection for people managing genital herpes.

Directions

  • Always follow your prescriber’s instructions.
  • For outbreaks, the typical dose is 500mg twice daily for 5–10 days.
  • For prevention of frequent flare-ups, your clinician may recommend a daily suppressive dose.
  • Swallow tablets whole with water, with or without food.
  • For best results, begin treatment as soon as the first symptoms appear.

Side Effects

Like all medicines, Valaciclovir can cause side effects, but most people tolerate it well. Side effects are usually mild and short-lived.

  • Tiredness – some people may feel slightly fatigued while on treatment.
  • Nausea or upset stomach – taking your dose with food may help reduce this.
  • Headache – often mild and manageable with hydration or simple pain relief.
  • Common (may affect up to 1 in 10 people):

 

Rare but serious (seek medical advice promptly):

  • Allergic reaction – signs include rash, swelling, or difficulty breathing.
  • Kidney problems – especially if dehydrated; drink plenty of fluids unless advised otherwise.
  • Confusion or dizziness – more likely in older adults or those with kidney conditions.

 

Disclaimer: This is not a complete list of side effects. Always read the patient information leaflet that comes with your medicine for full details. If you notice anything unusual or concerning, stop taking the medicine and seek medical advice promptly. In an emergency, call 999 or go to A&E.

Warnings

Do not use Valtrex if you:

  • Are allergic to valaciclovir, aciclovir, or any of the ingredients

 

Other cautions:

  • Stay hydrated while taking Valtrex
  • Speak to your clinician if you have kidney or liver problems (dose adjustments may be required)
  • Safe use during pregnancy or breastfeeding should be discussed with a healthcare professional
  • Tell your prescriber about all other medicines you’re taking

FAQ's

What’s the difference between Valtrex and generic Valaciclovir?
They contain the same active ingredient and work the same way. Valtrex is the branded version, which some patients prefer for reassurance and familiarity.

Does Valtrex cure herpes?
No — herpes cannot be cured, but Valtrex reduces the severity and duration of outbreaks and lowers recurrence rates.

Is Valtrex safe for long-term use?
Yes — it is often prescribed as suppressive therapy for people with frequent flare-ups.

How quickly does Valtrex work?
Starting treatment early can shorten outbreaks by 1–2 days and reduce pain.

Does Valtrex stop transmission completely?
No — while it reduces the risk, herpes can still be passed on. Condoms and avoiding sex during outbreaks provide extra protection.
