What is in this leaflet

This leaflet answers some common questions about Valaciclovir Sandoz.

It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you taking this medicine against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may need to read it again.

What Valaciclovir Sandoz is used for

This medicine is used to treat:

  • genital herpes infections (Herpes Simplex Virus, or HSV)
  • shingles (herpes zoster) and ophthalmic zoster (shingles affecting the eye region).

This medicine is also used to prevent cytomegalovirus (CMV) infection and disease, following solid organ transplantation. CMV is another type of herpes virus. It can cause symptoms similar to glandular fever (high temperature, sore throat and swollen glands).

It contains the active ingredient valaciclovir hydrochloride. Valaciclovir hydrochloride belongs to a group of medicines called antivirals.

It works by stopping the multiplication of the viruses which cause these infections.

For genital herpes infections:
Although Valaciclovir Sandoz does not cure the infection, it can reduce the length and severity of an outbreak of herpes, the duration of pain and shorten the time to healing. It also helps blisters to heal more quickly. If you start taking them as soon as you feel an outbreak starting, you may prevent the blisters from developing.

This medicine (or any other antiviral) does not cure genital herpes or completely eliminates the risk of transmission. Genital herpes is a sexually transmitted disease. Therefore, in addition to therapy with this medicine, it is recommended that you should minimize having intercourse when you have an outbreak of herpes or show any symptoms. Condoms should always be used. This will reduce the risk of spreading herpes to your partner.

For shingles affecting the body and eye region:
This medicine 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.

Ask your doctor if you have any questions about why this medicine has been prescribed for you.

This medicine is not addictive.

Valaciclovir Sandoz is available only with a doctor's prescription.

There is not enough information to recommend the use of this medicine for children under the age of 12 years.
