What VALNIR is used for

VALNIR is used to treat genital herpes simplex infection.

VALNIR contains valaciclovir (as valaciclovir hydrochloride) and belongs to a group of medicines called antivirals.

It works by stopping the multiplication of the virus which causes herpes.

VALNIR can reduce the length and severity of an outbreak and 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.

VALNIR tablets help the blisters to heal quicker. Taking the VALNIR tablets as soon as you feel an outbreak can help to prevent the blisters from developing.

VALNIR tablets can also be taken long term to help prevent the HSV infection returning.

VALNIR tablets are more effective in patients 50 years and over.

VALNIR tablets can also be taken continuously to reduce the risk of transmitting the virus that causes genital herpes or to reduce recurrent outbreaks. It does not cure genital herpes or completely eliminate risk of transmission. Therefore, in addition to therapy with VALNIR it is recommended that patients avoid contact when symptoms are present and always use condoms.

VALNIR 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.

Ask your doctor if you have any questions about why VALNIR has been prescribed for you. Your doctor may have prescribed it for another reason.

VALNIR tablets are available only with a doctor’s prescription.

There is no evidence that it is addictive.

How to take it

How much to take

Follow all directions given to you by your doctor. Your doctor will decide what dose you should take and how often you should take it. The dosage may vary depending on your medical history.

Short term treatment of genital herpes:
If you have had a herpes infection before, you should start to take VALNIR tablets as early as possible if you think you are about to have another recurrence. Dosing should ideally start before, or straight after the first signs of HSV infection appear. The usual dose is one VALNIR 500 mg tablet with water twice daily.

Long term treatment of genital herpes:
If you have been prescribed VALNIR 500 mg tablets to prevent the herpes infection appearing again, the usual dose to take is 500 mg once daily. Your doctor may recommend that you take this as a divided dose (i.e. 250 mg twice daily).

If you have had more than 10 recurrences in one year, your doctor may recommend that you take 1000 mg of VALNIR once daily to prevent recurrences.

How to take it

Swallow the tablets with a glass of water.

If you forget to take it

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

Otherwise, take the missed dose as soon as you remember, and then go back to taking your tablets as you would normally.

Do not take a double dose to make up for the dose you missed.

If you are not sure what to do, ask your doctor or pharmacist.

How long to take it

The usual course of treatment is five days. However, your doctor may want you to take your tablets for ten days.
