What the medication is used for
JAMP-VALACYCLOVIR is an antiviral medicine. It is used to lower the ability of herpes viruses to multiply in your body. JAMP-VALACYCLOVIR does not cure herpes infections.
What it does
JAMP-VALACYCLOVIR 500 mg tablets:
Treatment of shingles (herpes zoster)
JAMP-VALACYCLOVIR is used to treat shingles
(herpes zoster) infections. Shingles is caused by the
varicella-zoster virus which damages nerves and skin.
JAMP-VALACYCLOVIR helps stop the virus from
multiplying, therefore reducing the damage.
JAMP-VALACYCLOVIR 500 mg tablets:
Treatment or suppression of genital herpes
JAMP-VALACYCLOVIR 500 mg tablets are used to
treat genital herpes which is caused by the herpes
simplex virus (HSV).
HSV causes small, fluid-filled blisters in the genital
area which break down into ulcers/sores which may be
itchy or painful. The blisters contain many infectious
HSV particles. JAMP-VALACYCLOVIR helps stop
HSV from multiplying which helps to shorten the time
that the virus is shed from the skin and mucous
membranes. It reduces the number of painful blisters
and also helps them to heal more quickly.
If you start taking JAMP-VALACYCLOVIR as soon
as you feel an infection starting, you may actually
prevent the blisters from developing. This type of
treatment is called episodic therapy.
When taken every day, JAMP-VALACYCLOVIR can
also be used to prevent the HSV infection from
coming back. This type of treatment is called
suppressive therapy.
Reduction of transmission of genital herpes
JAMP-VALACYCLOVIR taken every day and in
combination with safer sex practices can reduce the
risk of transmitting genital herpes to your sexual
partner. This type of treatment is for reduction of
transmission.
Sometimes the herpes simplex virus (HSV) may be
released to the skin at levels too low to cause blisters –
this is called viral shedding.
With no visible symptoms, viral shedding can occur
anywhere in the “boxer short” area (from just below
the waistline down to the upper thighs, including the
buttocks). This means it is possible to transmit genital
herpes through skin-to-skin contact with the “boxer
short” area, even in the absence of blisters.
JAMP-VALACYCLOVIR helps stop HSV from
multiplying which helps to shorten the time that the
virus is shed from the skin and mucous membranes.
Treatment of cold sores (herpes labialis)
JAMP-VALACYCLOVIR is used to treat cold sores
(herpes labialis) which are caused by the herpes
simplex virus (HSV).
Cold sores are small, fluid-filled blisters that you get
in or around your mouth. The blisters then break down
into ulcers/sores which may be itchy or painful. The
blisters contain many infectious HSV particles. Cold
sores may be spread by kissing or other physical
contact with the infected area of the skin.
JAMP-VALACYCLOVIR helps stop HSV from
multiplying which helps to shorten the time that the
virus is released from the skin and mucous
membranes. It reduces the number of painful blisters
and also helps them to heal more quickly.

More information
What is genital herpes?
Genital herpes, one of the most common sexually transmitted infections, is caused by the herpes simplex virus (HSV), the same family of viruses that causes cold sores or fever blisters. You can get genital herpes by having sex (skin-to- skin contact including genital, anal, and/or oral contact) with a person who has herpes. Genital herpes does not always occur on the genitals. It may occur anywhere in the “boxer short” area for both men and women (from just below the waistline down to the upper thighs, including the buttocks).
Are there any warning signs of a genital herpes outbreak?
Many people have genital herpes and don’t even know it. Here are some of the signs and symptoms that may signal a genital herpes outbreak:- Swelling, pain, itching, or burning in your genital area
- Redness, tiny blisters, or sores
- Burning feeling when urinating
- Genital discharge
- Muscle aches, tiredness, or headaches
There is no cure for genital herpes. Once the herpes
virus enters the body, it is present throughout life,
alternating between active (outbreak or viral shedding)
and inactive states.
Why outbreaks recur is still unknown. Some people
know what triggers their genital herpes infection to
become active again, while others do not. Some
factors that may trigger the virus into activity are lack
of sleep, poor diet, stress and menstruation.
Try to notice if these factors cause your infection to
return, as you may be able to avoid some of them.
Taking your JAMP-VALACYCLOVIR as soon as
you get the warning signs may actually prevent the
blisters from developing.
How did I get genital herpes?
Genital herpes is passed from one person to another through direct intimate contact. It can be transmitted sexually, by direct contact with blisters or sores, which contain many infectious virus particles. It can also be transmitted through skin-to-skin contact with the “boxer short” area even in the absence of blisters, because the virus can be active on the skin without causing symptoms.Small cuts or scratches in the skin or mucous membranes allow the virus to gain entry into the body more easily. These may not be visible to the naked eye.
Genital herpes cannot be transmitted via handshakes, toilet seats, swimming pools, saunas, hot tubs or blood transfusions.
Can I transmit genital herpes to other people?
Yes. It is important to remember that the herpes virus can be shed from your skin even when you do not have any signs or symptoms. For this reason, you can transmit the infection to your partner through skin-to-skin contact with the “boxer short” area even in the absence of blisters or sores. In 70% of cases, genital herpes is transmitted when there are no signs or symptoms.How can I reduce the risk of transmitting genital herpes to other parts of my body or to other people?
You do not have to stop having sex if you have genital herpes.However, here are some things you should consider in order to reduce the risk of transmission:
- Avoid sexual contact with your partner when you have an outbreak of genital herpes, or think you are about to have an outbreak.
- Use latex or polyurethane condoms each time you engage in sexual intercourse even when there are no signs of infection.
- Avoid touching or breaking the blisters or sores and do not pick the scabs when they form.
- Always wash your hands if you touch the blisters, sores, or scabs.
- If you or your partner has an active genital herpes infection (or even the warning signs), avoid contact with the blisters or sores.
- When combined with safer sex practices, including condoms, daily therapy with JAMP-VALACYCLOVIR reduces the risk of transmitting genital herpes to your partner.
- Talk to your doctor about the best options for you and your partner.
What about genital herpes and pregnancy?
There is no evidence that having genital herpes affects fertility in men or women and is unlikely to complicate a pregnancy. The measures described above will also help to reduce the risk of transmitting genital herpes during pregnancy. Special precautions should be taken during pregnancy to avoid transmission to a pregnant woman if her partner has genital herpes. Care is needed at the time of birth if there is an active infection present. Discuss the options available with your doctor.
How can you treat (or manage) your genital herpes?
There are 3 different ways to manage genital herpes with JAMP-VALACYCLOVIR:Episodic therapy: Episodic therapy involves taking JAMP-VALACYCLOVIR for a specific number of days during an outbreak to help speed the healing of blisters, shorten the duration of pain and discomfort, and reduce viral shedding (the stage during which herpes virus is secreted). If treatment with JAMPVALACYCLOVIR is started before the appearance of any sores, it may prevent sores from occurring.
Suppressive therapy: JAMP-VALACYCLOVIR can also be used to help prevent outbreaks of genital herpes. JAMP-VALACYCLOVIR will not cure genital herpes, but, if taken every day, it may prevent genital herpes outbreaks before they start. Suppressive therapy can significantly reduce the frequency of outbreaks, although results will vary from person to person. Many people can remain recurrence-free while on suppressive treatment.
Reduction of Transmission: When taken every day, JAMP-VALACYCLOVIR in combination with safer sex practices can also reduce the risk of transmitting genital herpes to your sexual partner.
Talk to your doctor if you have questions about treatment with JAMP-VALACYCLOVIR and if you are concerned about transmitting genital herpes to your partner. Your physician will help you decide which type of therapy is best for you.
