What is this medicine used for
The name of your medicine is APOHEALTH FAMCICLOVIR ONCE. It contains the active ingredient, famciclovir.
Famciclovir is an antiviral medicine used to treat recurrent outbreaks of cold sores in adults 18 years of age and over who
have a normal immune system (the body system which fights against harmful bacteria, viruses and fungi).
Cold sores are an infection caused by a virus called herpes simplex type 1 (HSV-1). The infection is most commonly acquired
as a baby or child from contact with parents or relatives, often from kissing.
Cold sores usually begin on or around the lips, mouth, and nose as small red bumps that turn into fluid-filled blisters. Cold
sores can be tender and painful. Many people who get cold sores know when one is coming by a tingling, burning, itchy or painful
sensation or redness in the area. This can happen very rapidly.
After redness and swelling develop, blisters form. The blisters may weep or burst and this can be painful. Then a shallow
ulcer and yellow crust form as the cold sore dries. The crust eventually falls off, exposing new pink-coloured skin. Generally
the sores heal without scarring. After the initial infection has healed, the virus becomes dormant in nerve cells.
Cold sores can be unpredictable. The virus can become active again in the body, even after many years, resulting in recurrent
outbreaks. Even after many years, some people may experience recurring cold sores due to viral reactivation.
Some common triggers to a cold sore may include:
dry chapped lips
Although APOHEALTH FAMCICLOVIR ONCE does not cure the viral infection, it helps to relieve the symptoms and shorten the duration
of an outbreak.
The best results are obtained if the medicine is started as soon as possible after the onset of symptoms of a cold sore, such
as tingling, itching or burning, or the appearance of the first signs, such as redness or swelling. This is when the virus
is reproducing rapidly.
Ask your pharmacist or doctor if you have any questions about why this medicine has been prescribed for you.
This medicine is available only from your pharmacist and does not require a prescription.
There is no evidence that this medicine is addictive.
Use in children
Famciclovir is not recommended for use in children or adolescents under 18 years of age.

Some medicines and famciclovir may interfere with each other. These include:
probenecid, a prescription medicine used to treat gout (a disease with painful, swollen joints caused by uric acid crystals)
and to increase blood levels of penicillin-type antibiotics
raloxifene, a medicine used to treat osteoporosis (a disease which causes bones to become less dense, gradually making them
weaker, more brittle and likely to break)
medicines that can affect your kidneys.
medicines that can affect your immune system.

or you may need to take different medicines.
Your doctor and pharmacist can tell you if you are taking any of these medicines. They may also have more information on medicines
to be careful with or avoid while taking famciclovir.
Other interactions not listed above may also occur.
How to take this medicine

They may be different to the information in this leaflet.
If you do not understand any written instructions, ask your doctor or pharmacist for help.
How much to take
The usual dose is three 500 mg tablets taken together as a single dose.
However, if you have problems with your kidneys and your pharmacist has referred you to your doctor to see if this medicine
is suitable for you, your doctor may have recommended a different dose.

The tablets may be taken with or without food.
If you do not understand the instructions on the label, ask your doctor or pharmacist for help.
When to take it
Take APOHEALTH FAMCICLOVIR ONCE as soon as possible after the first symptoms (e.g. tingling, itching or burning) or signs
(e.g. redness or swelling) of a cold sore appear.
Do not take the tablets if a hard crust has already formed on the cold sore.
Keep the tablets for the next episode.
How long to take it
A single dose of famciclovir is all that is necessary for treating each episode of cold sores.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (Tel: 13 11 26 for Australia) for advice, or go to the
Accident and Emergency Department at the nearest hospital, if you think that you or anyone else may have taken too much famciclovir.

failure if their dose is not correctly lowered.
While you are taking this medicine
Things you must do
Tell your doctor or pharmacist if your cold sores symptoms do not improve within a few days, or if they become worse.
If you become pregnant while taking famciclovir, tell your doctor.
Your doctor can discuss with you the risks of taking it while you are pregnant.

This medicine can cause dizziness, sleepiness or confusion in some people.
Things that may help your condition
Cold sores are contagious and the virus that causes them can be passed on from person to person through close physical contact
or saliva, even when blisters are not present. The risk is much higher when the cold sore can be seen, as the virus can be
shed, making it easy to infect other people.
Take the following precautions to avoid spreading the virus:
Keep the areas affected by the virus as clean and dry as possible
Avoid touching or scratching the sore area as you may spread the virus on your fingers
Do not share any objects that have been in contact with a cold sore (e.g. drinking glasses, eating utensils, towels)
Avoid direct skin-to-skin contact of the area with other people (e.g. kissing) until the cold sore has healed.
Possible side effects
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking famciclovir.
