What this medicine is used for

Valaciclovir belong to a group of medicines called antivirals.

Valaciclovir is used for the following conditions in adults:

  • Treatment of herpes zoster (shingles):
    It can reduce the duration of pain, length and severity of a shingles outbreak. Start the treatment within the first three days of the shingles attack.
  • Treatment of ophthalmic zoster
    (shingles affecting the eye region)
  • Treatment of genital herpes:
    Valaciclovir can reduce the length and severity of a herpes outbreak, and reduce the duration of pain and time to healing of herpes blisters and crusts. It does not eliminate the herpes simplex virus (HSV) from the body. If you start taking it as soon as you feel an outbreak starting, you may prevent blisters from developing.

Prevention of genital herpes in immunocompromised patients with moderate to normal kidney function:

Valaciclovir can be taken by immunocompromised patients with adequate kidney function to help prevent the HSV infection coming back.

  • Reduction of transmission of genital herpes:
    Valaciclovir can reduce the risk of transmitting the HSV virus in patients who are taking it continuously. It does not cure genital herpes or eliminate the risk of transmission. Therefore, in addition to valaciclovir, it is recommended to avoid intercourse during a herpes outbreak and always use condoms to minimise the risk of spreading herpes to your partner.
  • Prevention of cytomegalovirus infection (CMV) and disease:
    Valaciclovir is used to prevent cytomegalovirus (CMV) infection and disease following solid organ transplantation. CMV is a type of herpes virus. It can cause symptoms similar to glandular fever (high temperature, sore throat and swollen glands).

How it works

Valaciclovir works by stopping the multiplication of the virus which causes shingles and herpes.

This medicine is not addictive.
