What Valaciclovir GA tablets are used for
Valaciclovir GA tablets belong to a group of medicines called antivirals. Valaciclovir GA tablets are used for the treatment of genital herpes infection.
Valaciclovir GA tablets work by stopping the multiplication of the virus which causes herpes. They 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.
Valaciclovir GA 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. Valaciclovir GA tablets can also be taken long term to help prevent the HSV infection coming back.
Valaciclovir GA is more effective in patients 50 years of age and older.
Valaciclovir GA tablets can also reduce the risk of transmitting the virus that causes genital herpes in patients who are taking it continuously to prevent or reduce recurrent outbreaks. It does not cure genital herpes or completely eliminate the risk of transmission. Therefore, in addition to therapy with Valaciclovir GA, it is recommended that patients avoid contact when symptoms are present and always use condoms.
Valaciclovir GA (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.
Ask your doctor if you have any questions about why Valaciclovir GA tablets have been prescribed for you.
Valaciclovir GA tablets are not addictive.

Take Valaciclovir GA tablets exactly as your doctor has prescribed. Your doctor or pharmacist will tell you:
- how many tablets to take at each dose
- how many doses to take each day
- when to take your doses each day.
The label on the pack will give the same information. If there is something you do not understand, ask your doctor or pharmacist.
How much to take
Your doctor will decide what dose you should take, how often you should take it and what strength Valaciclovir GA tablets you should use. The dosage may vary depending on your medical history.
Acute (short term) treatment of genital herpes:
If you have had a herpes infection before, you should start to take Valaciclovir GA tablets as early as possible if you think you are about to have another recurrence (attack). Dosing should ideally start just before, or straight after the first signs of HSV infection appear.
If you have been prescribed Valaciclovir GA 500 mg tablets for the treatment of HSV infection, the usual dose to take is one tablet with water twice daily.
Suppressive (long term) treatment of genital herpes:
If you have been prescribed Valaciclovir GA 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 (ie 250 mg twice daily).
If you previously have had more than 10 recurrences (attacks) in one year, your doctor may recommend that you take 1000 mg of Valaciclovir GA once daily to prevent recurrences.
If you think you have been advised to take a different dose, talk to your doctor or pharmacist.

For prevention of herpes infections, you should continue to take this medicine every day as prescribed by your doctor.
Do not stop taking Valaciclovir GA tablets just because you feel better. The herpes outbreak may not be completely over.
