Valaciclovir (Valtrex)

What is Valaciclovir?

Valaciclovir is an antiviral medicine that is available to purchase on prescription.

It is sometimes sold under the brand name Valtrex, among others.

Valaciclovir 500mg tablets are available to purchase at Medicine Direct. We can offer you next day delivery if you order before 2pm.

What is Valaciclovir used to treat?

Valaciclovir, along with Aciclovir, is the most commonly prescribed medication to provide effective treatment for the genital herpes virus.

Valaciclovir can be used to treat shingles, cold sores and the herpes simplex virus (HSV), commonly known as genital herpes. It can also be used to prevent a recurrence of a herpes simplex virus infection and to stop a CMV infection.

This treatment is available to purchase in packs of 10 tablets (to treat one outbreak), 20 tablets (to treat two outbreaks), or 30 tablets (to treat three outbreaks).

Dosage

Always take Valaciclovir tablets exactly as instructed by your doctor, and always thoroughly read the patient information leaflet for full details.

If you are unsure of anything, consult your doctor or pharmacist before you start the course of treatment.

Dosages of this medication vary depending on the condition you are being treated for. The recommended daily dose for this medicine as a treatment for genital herpes is one Valaciclovir 500mg tablet twice a day.

For the first infection, your doctor might tell you to use Valaciclovir for between 5 and 10 days. For a recurring infection, treatment normally lasts for between 3 and 5 days.

How to take Valaciclovir

To treat the herpes virus effectively, you should take the medication at the same time each day.

Swallow Valaciclovir tablets whole with a glass of water.

Always use this treatment exactly as instructed by your doctor.

You should make sure that you drink plenty of water throughout the day while using this medicine; this will help to reduce the risk of adverse effects that can affect your kidneys or nervous system.

What if I forget to take it?

If you forget to take a dose of Valaciclovir, just take it as soon as you remember. If it is almost time for your next scheduled dose, just skip the missed dose and continue to take the medication as normal.

You should never take a double dose of any medicine to try and make up for missing a previous dose.

Taking Valaciclovir consistently is vital to ensuring you can treat genital herpes effectively. To avoid missing a dose, it is best if you take it at the same time each day.

What if I take too much?

Valaciclovir is not usually harmful if you accidentally take too much. You should speak to your doctor if you become worried or if you take more than one extra dose.

Taking too much of this medicine may result in adverse effects.

How quickly does Valaciclovir take to start working?

Your symptoms may be reduced after 3 days. Do not stop taking the medicine if you think your symptoms have fully gone as the herpes virus may still be present in your body, which means you may spread it to others. Valaciclovir reaches its peak concentration in your blood within one to three hours of taking it.

Whether you are being treated for genital herpes or another condition, you should always complete your course of treatment as instructed by your doctor, even if your symptoms appear to have gone.
