Description
What Famvir is and what it is used for
Famvir is an antiviral medicine. It stops the infecting virus from reproducing. Since the virus reproduces very early in the infection, you will benefit most from treatment if you take Famvir as soon as the first symptoms appear.
Famvir is used in adults to treat shingles (herpes zoster) and recurrent outbreaks of genital herpes. Famvir is not a cure for herpes infections.
Shingles (herpes zoster)
Shingles (herpes zoster) is a viral infection caused by varicella zoster virus (the same virus that causes chickenpox).
The safety and effectiveness of Famvir for shingles in the eye(s) (ophthalmic zoster) have not been established.
Genital herpes
Genital herpes is a viral infection caused by herpes simplex virus type 1 or 2. It is normally spread by sexual contact. It causes blisters and burning or itching around the genitals, which may be painful.
Famvir is used to treat recurrent genital herpes outbreaks in adults. People who have frequent outbreaks of genital herpes can also take Famvir as suppressive therapy to help reduce the number of outbreaks. The safety and effectiveness of suppressive therapy beyond 1 year have not been established.
Before you take Famvir
Do not take Famvir
If you are allergic (hypersensitive) to famciclovir, to any of the ingredients in Famvir, or to penciclovir (e.g. Denavir® (penciclovir cream)). Ask your doctor for advice, if you think you may be allergic.
Take special care with Famvir
If you have kidney problems (or have had them before). Your doctor may decide to give you a lower dose of Famvir.
If you have problems with your body's immune system. If you have liver problems. If any of these applies to you, tell your doctor before you take Famvir.
Children and adolescents (below the age of 18 years)
Famvir is not recommended for use in children and adolescents.
Prevent passing genital herpes to others
If you are taking Famvir to treat or to suppress genital herpes, or you have had genital herpes in the past, you should still practise safe sex, including the use of condoms. This is important to help reduce the risk of passing the infection on to others. You should not have sex if you have genital sores or blisters.
Taking other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.
It is especially important that you tell your doctor or pharmacist if you take probenecid, as it may increase penciclovir levels.
Taking Famvir with food and drink
You can take Famvir with or without food.
Pregnancy and breast-feeding
Ask your doctor or pharmacist for advice before taking any medicine.
If you are pregnant or plan to become pregnant, tell your doctor. It is not known if Famvir will harm your unborn baby.
If you are breast-feeding or plan to breastfeed, tell your doctor. It is not known if Famvir passes into breast milk or how it may affect a breastfed baby.
Driving and using machines
Famvir can cause dizziness, drowsiness or confusion. Do not drive or use machines if you have any of these symptoms while taking Famvir.
Important information about some of the ingredients of Famvir
If you have been told by your doctor that you have an intolerance to some sugars, e.g. lactose, contact your doctor before taking this medicine. Famvir 125 mg, 250 mg and 500 mg tablets contain lactose.
How to take Famvir
Always take Famvir exactly as your doctor has told you. You should check with your doctor or pharmacist if you are not sure.
The daily dose and length of treatment will depend on the type of viral infection you have - see below. Your doctor will prescribe the correct dose for you.
For the best results start the medicine as soon as possible after the first signs and symptoms appear.
Do not have sexual contact with anyone if you have symptoms of genital herpes - even if you have started treatment with Famvir. This is because you could pass the herpes infection to your partner.
If you have or have had kidney problems, your doctor may decide to give you a lower dose of Famvir.
Dose for shingles
If you have a normal immune system, the recommended dose is one tablet of 500 mg, three times a day, for seven days.
Dose for genital herpes
The dose depends on the stage of your infection.
Famvir is not indicated for the first outbreak of genital herpes.
To treat recurrent outbreaks, the recommended dose is: 1000 mg twice daily for 1 day.
To help prevent future outbreaks (suppressive therapy), the recommended dose is: one tablet of 250 mg twice a day. Your doctor will tell you how long you need to continue taking your tablets.
The safety and effectiveness of Famvir have not been established in immunocompromised patients, except for treatment of recurrent orolabial or genital herpes in HIV-infected adults (500 mg twice daily for 7 days).
If you take more Famvir than you should
If you have taken more tablets than you have been told to take, or if someone else accidentally takes your medicine, go to your doctor or hospital for advice immediately. Show them your pack of tablets.
Taking too much Famvir 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.
If you forget to take Famvir
If you miss a dose of Famvir, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and take your next dose as scheduled. Do not take two doses at the same time to make up for a missed dose.
If you have any further questions on the use of this product, ask your doctor or pharmacist.
