What FAMVIR is used for
FAMVIR is an antiviral medicine for adults and adolescents. It is used to treat outbreaks of genital herpes and also to suppress
(prevent) recurrent outbreaks of the condition. Genital herpes is a viral infection caused 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 blisters that may be painful.
People who have frequent episodes of genital herpes can also take FAMVIR to help prevent the attacks.
Although FAMVIR 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 FAMVIR does not prevent you from spreading the herpes virus to another person.
Ask your doctor if you have any questions about why this medicine has been prescribed to you.
Your doctor may have prescribed it for another reason.
FAMVIR is only available with a doctor's prescription. It is not addictive.
This medicine is not recommended for use in children under 12 years of age.
Before you take FAMVIR
When you must not take it

swelling of the face, lips, tongue or other parts of the body;
rash, itching or hives on the skin.
Do not take FAMVIR after the expiry date printed on the pack or if the packaging is torn or if it shows signs of tampering.
In that case, return it to your pharmacist.
Before you start to take it
Tell your doctor if you have a problem with:
your body's immune system, which helps to fight off infections
Your doctor may want to take extra precautions in that case.
Tell your doctor if you are pregnant, intend to become pregnant or if you are breast-feeding.
FAMVIR should not be used during pregnancy unless necessary. Your doctor will discuss with you the potential risks of taking
FAMVIR during pregnancy, and will also advise you if you should take FAMVIR while breast-feeding, based on the benefits and
risks of your personal situation.

FAMVIR 125 mg tablets and 250 mg tablets contains lactose. FAMVIR 500 mg tablets do not contain lactose.
Tell your doctor if you are allergic to any other medicines, foods, dyes or preservatives.
Your doctor will want to know if you are prone to allergies.
If you experience an allergic reaction, stop using the medicine and inform your doctor or pharmacist immediately.
Taking other medicines
Tell your doctor if you are taking any other medicines, including any that you buy without a prescription from a pharmacy,
supermarket or health food shop.
Some medicines and FAMVIR 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.
You may need to take different amounts of these medicines or you may need to take different medicines. Your doctor and pharmacist
have more information.
If you have not told your doctor about any of these things, tell him/her before you start taking this medicine.
How to take FAMVIR
Swallow the tablets whole with a full glass of water.
The tablets may be taken with or without food. It is not necessary to chew or crush the tablet.
If you do not understand the instructions on the label, ask your doctor or pharmacist for help.
How much to take
Follow your doctor's instructions on how many FAMVIR tablets to take.
These instructions may differ from the information contained in this leaflet.
Do not change the dose yourself, without your doctor's advice, regardless of how well you may feel.
Ask your doctor or pharmacist if you are unsure of the correct dose for you.
They will tell you exactly how much to take.
For people whose immune system does not work as well as it should, the dose and duration of treatment may need to be increased.
For people who have kidney problems, your doctor may decide to give you a lower dose.
When to take it
There are different ways to take FAMVIR depending on your condition.
1.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 three ways to take FAMVIR to treat an outbreak of genital herpes and your doctor will tell you which regimen is
best for you:
Two 500 mg FAMVIR tablets twice daily for one day
Two 250 mg FAMVIR tablets to start with, followed by one 250 mg tablet every 12 hours for the next 3 doses
One 125 mg FAMVIR tablet every 12 hours for 5 days
Take the second dose (and subsequent doses, if applicable) 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.
2.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 FAMVIR
Take one 250 mg FAMVIR tablet twice each day.
Continue to take one 250 mg FAMVIR 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 long to take it
Continue taking FAMVIR every day for as long as your doctor tells you.
To help clear up your infection, you must keep taking this medicine, even if your symptoms begin to clear up after a few days.
To prevent recurrent episodes of genital herpes, you must take the tablets each day, even if you have no symptoms.
It is important to keep taking your medicine even if you feel well.
If you forget to take it
Take a dose as soon as you remember. Take your next tablet at the usual time, and then go back to taking it as you would normally.
Do not take two doses within a time frame of less than one hour. In that case, skip the missed dose.
Do not take a double dose to make up for the one that you missed.
This may increase the chance of you getting an unwanted side effect.
If you have trouble remembering when 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 number 13 11 26), or go to Accident and Emergency
at your nearest hospital if you think that you or anyone else may have taken too much FAMVIR. Show them your pack of tablets.
Do this even if there are no signs of discomfort or poisoning. Keep the telephone numbers for these places handy.

failure if their dose is not correctly lowered.
