Valtrex (Valacyclovir) is a prescription anti-viral medication. It is a highly effective medication used for viral infection treatment.


Valtrex is used in adults and in paediatric practice. Children may be prescribed Valtrex to treat chickenpox and cold sores (herpes simplex) or shingles (herpes zoster).

In adults, Valtrex is applied to medicate genital herpes flair-ups. When patients have multiple outbreaks (2 or more per year). Administration of Valtrex reduces the flair-ups frequency in the future.

How does Valtrex work?

Although Valtrex is an effective antiviral medication. The effect of Valtrex is based on the ability of the preparation to end the growth of the virus, it cannot stop the disease completely. The viruses (like herpes and others) keep living in the human body between the outbursts. However, Valtrex weakens the intensity of disturbing symptoms (like aching and itchiness) and shortens the flair-up periods. It also helps healing the sores more rapidly and stops forming new ones.

! If you have regular herpes outbursts it is recommended to keep Valtrex at home so the treatment can be started immediately.

How to take Valtrex

Valtrex comes in the form of tablets and has to be swallowed with a lot of fluids (to reduce the risk of side effects).

For patients under 12 years old, the medication dosage is calculated considering the child’s weight. For adults, the daily dosage depends on the type of infection, response to treatment, the age and overall health condition of the patient.

Specialists recommend Valtrex treatment at the first manifestations of exacerbation of herpes. If the treatment is delayed if would negatively affect the result.

To keep the constant level of antiviral medication in the blood level Is it highly recommended taking Acyclovir regularly at the same time every day with plenty of water.
