Patient Reviews: How Valaciclovir Has Made a Difference

Get Valaciclovir Tablets For Herpes Online UK

Valaciclovir, sometimes spelt valacyclovir, is an antiviral medication used to treat viruses including shingles and herpes.

The medicine is also available under the brand name Valtrex from our UK pharmacy.

You can order valaciclovir tablets for herpes from Prescription Doctor. To get started, simply press the green button above and fill out our medical form.

The herpes virus is transmitted through skin-to-skin contact. The virus can be transmitted through kissing, touching the genitals, sexual intercourse and sharing glassware or dining utensils with infected persons.

While herpes can be transmitted when in its dormant state, the virus is more infectious when active and symptoms are present.

Symptoms of herpes include:

  • Blisters around the genitals or anus
  • Cold sores around the mouth
  • Itching and burning feeling around the genitals
  • Pain when urinating
  • Vaginal discharge

Once a person is infected with herpes, the virus remains in the body for the rest of your life.

The herpes virus may reactivate, causing unpleasant symptoms to develop. It is when these symptoms develop that the virus becomes transmissible.

While there is no cure, there are treatments which help the body's immune system suppress the virus back into remission.

When you purchase valaciclovir tablets from Prescription Doctor, our prescribing doctor will ensure they are safe for you.

If your order is approved before 3pm on weekdays, our UK pharmacy can dispatch your order the same day via a fast and discreet next-day delivery.

How Does Valaciclovir Work?

Valaciclovir (sometimes spelt valacyclovir) is converted into the active form aciclovir inside the body. It works by inhibiting the enzyme the virus needs to grow and multiply in the body's cells.

This helps the body's immune system fight the virus infection back into remission.

How long does valaciclovir take to work?

You should start to feel relief from your symptoms in just two or three days of taking valaciclovir.

You may be prescribed to take valaciclovir for between 5 and 10 days. It's important that you follow the doctor's instructions.

How Do I Take Valaciclovir?

To treat genital herpes, the usual dose is 500 mg twice daily, taken for three to five days.

Valaciclovir tablets should be swallowed whole with a glass of water.

Do not crush or chew the tablets.

Always take valaciclovir tablets as prescribed by the doctor.

What should I do if I forget to take valaciclovir when I should?

If you forget to take valaciclovir when you should, take it as soon as you remember.

If it is almost time for your next dose, skip the missed dose and continue to take valaciclovir as you normally would.

Do not take more valaciclovir to make up for the dose you missed.

What should I do if I take more valaciclovir than I should?

If you accidentally take more valaciclovir than you should, speak to your doctor.

Taking more medicine than prescribed is unlikely to treat your symptoms any faster, but may increase your chance of experiencing side effects.

Valaciclovir Side Effects and Cautions

Before you begin taking any medicine, it's important to familiarise yourself with the safety information displayed in the patient information leaflet.

The patient information leaflet contains instructions on how to use, store and dispose valaciclovir, as well as important information regarding the medicine's safety.

You can view the patient information leaflet for valaciclovir online and download it or print it off.

Who should not use valaciclovir?

Valaciclovir is not suitable for everyone, and may react with medicines you are already taking.

You should speak to your doctor or a pharmacist before taking valaciclovir if you:

  • have kidney problems
  • have liver problems
  • are over the age of 65

You should inform our medical team of all medicines you are currently taking before taking valaciclovir.

This includes medicines prescribed to you by your doctor, as well as those bought over the counter, and health or herbal supplements.

It is especially important to mention medicines which affect the kidneys, including:

  • Aminoglycosides
  • Oranoplatinum compounds
  • Iodinated contrast media
  • Methotrexate
  • Pentamidine
  • Foscarnet
  • Ciclosporin
  • Tacrolimus
  • Cimetidine
  • Probenecid

If you are unsure whether it is safe for you to take valaciclovir, speak to your doctor.

Valaciclovir side effects

All medications carry the risk of side effects. It's important to educate yourself on the risks associated with the medication you are taking and to know when you should seek medical attention.

Always read the patient information leaflet before taking any medication.

Common side effects of valaciclovir include:

  • Diarrhoea
  • Itching
  • Nausea
  • Rash
  • Sensitivity to sunlight
  • Vomiting

This is not an exhaustive list of side effects. Further information regarding the safety of valaciclovir, including a complete list of side effects, can be found in the patient information leaflet enclosed with your medicine.

If you experience any side effects, regardless of whether they are listed above or in the patient information leaflet, speak to your doctor or a pharmacist.


Do not take valaciclovir if you are allergic to valaciclovir, aciclovir or any of the other ingredients listed in the patient information leaflet.

If you experience an allergic reaction to valaciclovir, seek immediate medical attention by going straight to your nearest accident and emergency department. Remember to take the packaging and any remaining tablets with you so that doctors know exactly what you have taken.

Signs of an allergic reaction include:

  • Chest tightening
  • Dry, red and cracked skin
  • Itchy, red watery eyes
  • Raised, itchy, red rash (hives)
  • Swelling of the lips, tongue, eyes or face
  • Tummy pain, nausea, vomiting or diarrhoea
  • Wheezing

Pregnancy and breastfeeding

If you are pregnant, think you might be pregnant or breastfeeding, speak to your doctor before taking valaciclovir.

Your doctor will be able to determine whether the benefits of taking valaciclovir outweigh any risk posed to you and your baby.

It is very important to get treatment for herpes during pregnancy. The virus can be passed on to the child, resulting in neonatal herpes, which can be fatal.

Other safety information

Inform our medical team of all other medicines you are currently taking, including those prescribed by your doctor, or bought over the counter, as well as health and herbal supplements.

While treating genital herpes, it's important to wear a condom to prevent passing the virus on to your partner.

Do not take valaciclovir past the expiry date printed on the packaging. The date refers to the last day of the specified month.

Never throw away medicine via household or water waste. Ask your local pharmacy if they are able to dispose of any unwanted or expired medicine on your behalf.

Always store medicine out of sight and reach from children and pets.

Never share medicine which has been prescribed for you with other people.
