What this medicine is used for
Famciclovir is used to treat outbreaks of genital herpes and to suppress (prevent) recurrent outbreaks of the condition in adults and adolescents.
It belongs to a group of medicines called antivirals.
How it works
Genital herpes is a viral infection caused by Herpes Simplex 1 (HSV 1) or Herpes Simplex 2 (HSV 2). It is usually transmitted through sexual contact.
Symptoms include tingling, burning or itching of the genitals, followed by blisters that may be painful.
Famciclovir works by stopping the multiplication of the virus that causes genital herpes. Although famciclovir 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.
People who have frequent episodes of genital herpes can also take famciclovir to help prevent the attacks.
Taking famciclovir 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 for you.
Your doctor may have prescribed famciclovir for another reason.
This medicine is available only with a doctor’s prescription.
This medicine is not addictive.
Famciclovir is not recommended for use in children under 12 years of age.

Taking other medicines
Tell your doctor or pharmacist if you are taking any other medicines, including any that you buy without a prescription from your pharmacy, supermarket or health food shop.
Some medicines and famciclovir may interfere with each other. These include:
probenecid, a prescription medicine used to treat gout and to increase blood levels of penicillin-type antibiotics

medicines that can affect your kidneys.
These medicines may be affected by famciclovir or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.
Your doctor and pharmacist 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
Follow all directions given to you by your doctor or pharmacist carefully.
They may differ to the information contained in this leaflet.
If you do not understand the instructions on the label, ask your doctor or pharmacist for help.
How much to take
Your doctor or pharmacist will tell you how many tablets you will need to take. This depends on your condition and whether you are taking any other medicines.
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 reduced kidney function, the dose may need to be reduced.
Your doctor may have prescribed a different dose.
To treat an outbreak of genital herpes:
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 famciclovir to treat an outbreak of genital herpes. Your doctor will tell you which regimen is best for you:
Take two 500 mg tablets twice daily for one day
or
Take two 250 mg tablets to start with, followed by one 250mg tablet every 12 hours for the next 3 doses
or
Take one 125 mg tablet every 12 hours for 5 days.
For dosing regimens with 12-hourly dosing, take the second (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.
To suppress (prevent) outbreaks of recurrent genital herpes:
The usual dose is one 250 mg tablet taken twice each day.
Continue to take this medicine for as long as your doctor tells you to. Do this even if you do not have an outbreak.
How to take it
Swallow the tablets whole with a full glass of water.
The tablets may be taken with or without food.
When to take it
Take the tablets at about the same time each day.
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 famciclovir 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.
This medicine helps to control your condition but does not cure it. Your doctor will tell you when you can stop. It is important to keep taking your medicine even if you feel well.
If you forget to take it
If it is almost time to take your next dose, skip the dose you missed and take your next dose when you are meant to.
Otherwise, take it as soon as you remember, and then go back to taking it as you would normally.
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 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 famciclovir. Do this even if there are no signs of discomfort or poisoning.
You may need urgent medical attention.
Taking too much famciclovir may affect the kidneys. In people who already have kidney problems, it may, rarely, lead to kidney failure if their dose is not correctly lowered.
While you are taking this medicine
Things you must do
If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking famciclovir.
Tell any other doctors, dentists, and pharmacists who are treating you that you are taking famciclovir.
If you become pregnant while taking famciclovir, immediately tell your doctor.
For suppressing recurrent outbreaks, make sure to 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.
Keep all of your doctor’s appointments so that your progress can be checked.
Your doctor may do some tests from time to time to make sure the medicine is working and to prevent unwanted side effects.
Things you must not do
Do not take this medicine to treat any other complaints unless your doctor tells you to.
Do not give this medicine to anyone else, even if they have the same condition as you.
Do not stop taking your tablets or change the dosage without checking with your doctor first.
If you stop your tablets suddenly, your condition may worsen, or you may have unwanted side effects.
Things to be careful of
Be careful driving, operating machinery or doing jobs that require you to be alert until you know how famciclovir affects you.
This medicine can cause dizziness, tiredness or confusion in some people. If you have any of these symptoms, do not drive, operate machinery or do anything else that could be dangerous.
Practice “safer sex”, including the use of condoms, when symptoms are present, even if you have started taking famciclovir.
This is important to prevent you passing the infection onto others.
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.
