What is Valtrex?

Valtrex is used as an antiviral drug to alleviate symptoms and cure bouts of the herpes simplex virus, including genital herpes, cold sores and shingles. It helps the body to fight the infection by slowing down the growth of the herpes virus allowing the immune system is fight off the infection far quicker than avoiding treatment completely. Herpes is a chronic lifelong condition so no medicine has the ability to cure herpes, but Valtrex can significantly reduce uncomfortable symptoms of the infection and shorten the duration of the outbreak.

Starting herpes treatment as soon as possible will result in maximum effectiveness so doctors advise beginning your dosage within the first 24 hours of experiencing symptoms of the virus. You can buy Valtrex to provide relief from the symptoms of cold sores, shingles and genital herpes at euroClinix and receive your dosage tomorrow when ordered before 4.30pm. This means Valtrex will reduce symptoms within 24 hours and decrease the amount of time the virus is active. This helps you to recover much quicker, and will make the condition much less uncomfortable and painful.

How does Valtrex work?

Valtrex is an antiviral tablet also known as a pro-drug, which means that it is only converted into its most active state when it's inside the body. The main ingredient is valacyclovir hydrochloride, but once ingested it becomes the fast acting active ingredient acyclovir. This helps Valtrex combat the virus by preventing a viral enzyme, known as DNA polymerase, from helping the outbreak duplicate itself and spread from one healthy cell to another. The virus - whether it's genital herpes, cold sores and shingles – is then driven back into a dormant state quicker by the body's immune system.

When used as a preventative treatment, a steady dosage of Valtrex will successfully keep the viral infection at bay.

How to take Valtrex

Valtrex capsules are available in a dosage of 500mg from euroClinix. This is the recommended and ideal dose for many looking to use Valtrex for symptomatic relief of the sexually transmitted or viral infection. This medicine should be taken in differently depending on the type of infection you want to treat. Guidelines are detailed below before you commit to buying Valtrex online and the patient leaflet is also attached at the bottom of the page:

  • To treat recurrent cold sores outbreaks, two 500mg Valtrex tablets need to be taken for three to five days
  • To treat an initial cold sore outbreak, two 500mg Valtrex tablets are taken for up to ten days
  • To treat shingles, take two Valtrex 500mg tablets three times per day for seven days
  • To treat a recurrent genital herpes outbreak, take two tablets for three to five days
  • To treat an initial genital herpes outbreak, take two 500mg tablets each day for up to ten days
  • If you want to use this medication as a preventative treatment, then you should take one 500mg tablet each day

Valtrex dosages

You can buy Valtrex in a dosage of 500mg, which is recommended for many people experiencing a herpes outbreak. This is available in a quantity of 10 tablets, 20 tablets or 42 tablets depending on the severity, whether it is being used for genital herpes, shingles and cold sores, or if it is being used as a preventative treatment.

This antiviral is available in 1,000mg but this is for severe cases of herpes simplex and should be discussed with your doctor in person.

Precautions of Valtrex

The majority of people over the age of 18 who require treatment for cold sores, shingles or genital herpes can buy Valtrex safely online. It should usually be taken when you first notice symptoms, but the medication can be taken as a preventative treatment for genital herpes, to stop sporadic painful outbreaks.

Although this medicine is generally safe for most people to use, it is not recommended that people with kidney or liver conditions use this antiviral treatment. It is also not advised to use this medication if you suffer from immune deficiency disorders such as HIV.

Make sure to mention if you are pregnant or breastfeeding during your consultation as a doctor may recommend an alternative treatment.

This treatment may also not be suitable if you suffer from depression.

It is important to mention any other information relevant to your health or medications you may be taking during your consultation to ensure that Valtrex is not only safe for you to use but will have maximum effectiveness as well.

Valtrex side effects

People who buy Valtrex usually do not experience side effects however, some people tend to be more sensitive to the ingredients in this treatment than others. The side effects are normally mild and include nausea and headaches. Some of the less common side effects are abdominal pain, painful periods, vomiting, dizziness, joint pain and depression.

If you are taking this medicine for the first time you are more likely to experience side effects because your body isn't yet used to the ingredients, however, your body will eventually adapt if you are using it for more than a day.

Side effects will generally be more common in preventative treatment as this is taken continual over a longer period of time. For those using Valtrex as a temporary antiviral for a recurrent outbreak, side effects are highly unlikely. If you do experience mild side effects, these tend to pass quickly once you stop taking the medication.
