What VALACOR 500 tablet is used for
VALACOR 500 tablets contain valaciclovir (as hydrochloride). VALACOR 500 tablets belong to a group of medicines called anti-virals.
VALACOR 500 tablets are used for one or more of the following in adults:
- Treatment of Herpes zoster (shingles): Valaciclovir works by stopping the multiplication of the virus which causes shingles. It can reduce the length and severity of an outbreak of shingles and the duration of pain associated with shingles. It is important the treatment is started within the first three days of the shingles attack.
- Treatment of Ophthalmic zoster (shingles affecting the eye region)
- Treatment of genital herpes infection: Valaciclovir works by stopping the multiplication of the virus which causes herpes. It can reduce the length and severity of an outbreak of herpes, the duration of pain and shorten the time to healing of crusts associated with herpes. They do not eliminate the herpes virus from the body. The herpes virus is also known as the Herpes Simplex Virus, or HSV.
VALACOR 500 tablets help the blisters to heal more quickly. If you start taking them as soon as you feel an outbreak starting, you may actually prevent the blisters from developing.
- Prevention of genital herpes in immunocompromised patients with moderate to normal kidney function:VALACOR 500 tablets can be taken by immunocompromised patients (with moderate to normal kidney function) to help prevent the HSV infection coming back. It will be determined by your doctor if you should be given VALACOR 500 tablets or not.
- Reduction of risk of transmission of genital herpes:VALACOR 500 can reduce the risk of transmitting the virus that causes genital herpes in patients who are taking it continuously. It does not cure genital herpes or completely eliminate the risk of transmission. Therefore, in addition to therapy with valaciclovir, it is recommended that patients avoid contact when symptoms are present and always use condoms.
Valaciclovir (or any other antiviral) is not a cure for genital herpes. Because genital herpes is a sexually transmitted disease, you should minimise having intercourse when you have an outbreak of herpes or show any symptoms. This will avoid the risk of spreading herpes to your partner.
- Prevention of cytomegalovirus infection (CMV) and disease:VALACOR 500 tablets are 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).
Ask your doctor if you have any questions about why VALACOR 500 tablets have been prescribed for you.
VALACOR 500 tablets are available only with a doctor’s prescription.
