Consumer Medicine Information
What is in this leaflet
This leaflet answers some common questions about FAVIC.
It does not contain all of the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have benefits and risks. Your doctor has weighed the risks of you taking FAVIC against the benefits they expect it will have for you.
Talk to your doctor or pharmacist if you have any concerns about taking this medicine.
Keep this leaflet with your medicine. You may need to read it again.
What FAVIC is used for
FAVIC is an antiviral medicine that is used to treat outbreaks and prevent recurrent outbreaks of genital herpes in adults and adolescents.
Genital herpes is a viral infection causes by herpes simplex 1 or herpes simplex 2. It is usually transmitted through sexual contact.
Symptoms include tingling, burning or itching of the genitals, followed by the appearance of blisters which may be painful.
People can also take FAVIC to help prevent frequent episodes of genital herpes.
Although FAVIC does not cure the viral infection, it helps to relieve the symptoms and shorten their duration.
The best results are obtained if the medicine is started as soon as possible after the first symptoms begin to appear.
Taking FAVIC does not prevent you from spreading the herpes virus to another person.
Your doctor may have prescribed this medicine for another reason. Ask your doctor if you have any questions about why FAVIC has been prescribed for you.
It is available only with a doctor's prescription.
There is no evidence that FAVIC is addictive.
FAVIC is not recommended for use in children under 12 years of age, as the safety and efficacy of famciclovir in this age group has not been established.

Your doctor may want to take special care if you have any of these conditions.

How to take it
Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.
If you do not understand the instructions on the box, ask your doctor or pharmacist for help.
How much to take
To treat an outbreak of genital herpes
To treat an outbreak, take the tablets as soon as possible after the first symptoms of genital herpes appear. The tablets are best taken within 6 hours of the first symptoms of genital herpes appearing.
There are two ways to take FAVIC to treat an outbreak of genital herpes and your doctor will tell you which regimen is best for you:
- Two 250 mg FAVIC tablets to start with, followed by one 250 mg tablet every 12 hours for the next 3 doses
- One 125 mg FAVIC tablet every 12 hours for 5 days
Both of these outbreak treatment doses deliver the same total quantity of famciclovir (1250 mg) during the treatment course.
Take the second and subsequent doses 12 hours after the first dose, or as close as possible to 12 hours during waking hours. If you take the first dose in the late morning or early afternoon, you can take the next dose before going to bed, but do not take any doses less than 6 hours apart.
During normal waking hours, take any remaining doses at 12 hourly intervals.
Your doctor may have prescribed a different dose so follow their instructions carefully.
To suppress (prevent) outbreaks of recurrent genital herpes
Start suppressive treatment to prevent outbreaks of recurrent genital herpes as soon as possible after you have your FAVIC prescription filled.
Take one 250 mg FAVIC tablet twice each day.
Continue to take one 250 mg FAVIC tablet twice each day for as long as your doctor tells you to. Do this even if you do not have an outbreak. This medicine helps to control your condition but does not cure it. Your doctor will tell you when you can stop.
Fill your next repeat prescription before using all of the tablets in your current carton. This will ensure that your treatment can be continued and give you the best results.
Try to take the tablets at about the same times each day, as directed by your doctor or pharmacist. Taking your tablet at the same times each day will have the best effect. It will also help you remember when to take the tablets.
How to take FAVIC
Swallow the tablets whole with a full glass of water.
How long to take it for
Continue taking your medicine for the full course of treatment or for as long as your doctor tells you to. To help clear up your infection, you must take the full course of treatment, even if you feel your condition has improved after a few days.
If you forget to take it
Take it as soon as you remember, and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for the dose that you missed.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much FAVIC. Do this even if there are no signs of discomfort or poisoning. You may need medical attention.
While you are taking it
Things you must do
If you become pregnant while taking FAVIC, tell your doctor. Your doctor can discuss with you the risks of taking FAVIC while you are pregnant.
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking FAVIC.
Tell any other doctor, dentist or pharmacist who treats you that you are taking this medicine.
Things you must not do
Do not stop taking FAVIC, or lower the dose without checking with your doctor.
Do not take it to treat any other conditions unless your doctor tells you to.
Do not give FAVIC to anyone else, even if they have the same condition as you.
Things to be careful of
Be careful driving or operating machinery until you know how FAVIC affects you. This medicine can cause dizziness, sleepiness or confusion in some people.
Avoid sexual intercourse when symptoms are present, even if you have starting taking FAVIC, because the risk of infecting your partner is increased.
Things that may help your condition
Take the following precautions to help manage your condition:
- use condoms between episodes to reduce the risk of infecting your partner
- keep the areas affected by the virus as clean and dry as possible
- wear loose-fitting clothing to avoid irritating the blisters
- avoid touching or scratching the sore area as you may spread the virus on your fingers.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking FAVIC. All medicines can have side effects. Sometimes they are serious, most of the time they are not. You may need medical attention if you get some of the side effects.
Do not be alarmed by this list of possible side effects. You may not experience any of them.
Ask your doctor or pharmacist to answer any questions you may have.
Tell your doctor if you notice any of the following and they worry you:
- nausea (feeling sick) or vomiting
These side effects are usually mild.
Tell your doctor as soon as possible if you notice any of the following:
- a rash on other parts of your body
- extreme sleepiness or confusion, usually in older people
- hallucinations (seeing or hearing things that are not really there)
- painful or swollen joints
- aching muscles or muscle tenderness or weakness that is not caused by exercise.
You may need medical attention if you have the above side effects.
Tell your doctor immediately, or go to Accident and Emergency at the nearest hospital if you notice any of the following:
- bruising or bleeding more easily than usual as it may indicate that the number of platelets (a type of blood cell responsible for blood clotting) in your blood are reduced
- signs of a serious skin or mouth reaction, which may include widespread red, raised areas, blisters or sores
- signs of a possible liver problem such as persistent pain in the upper right abdomen, yellowing of the skin and/or eyes, dark urine or pale bowel motions.
These are serious but very rare side effects. You may need urgent medical attention or hospitalisation.
Other side effects not listed above may also occur in some patients. Tell your doctor if you notice anything that is making you feel unwell.
After taking it
Keep FAVIC where children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.
Keep your tablets in the blister pack until it is time to take them. If you take tablets out of the pack they may not keep well.
Keep your tablets in a cool dry place where the temperature stays below 25°C.
Do not store FAVIC or any other medicine in the bathroom or near a sink.
Do not leave FAVIC in the car or on window sills. Heat and dampness can destroy some medicines.
If your doctor tells you to stop taking FAVIC, or your tablets have passed their expiry date, ask your pharmacist what to do with any that are left over.
