1. 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 to treat two types of viral infections in adults:
- Shingles (herpes zoster), which is a viral infection caused by a virus called varicella zoster (the same virus that causes chickenpox). Famvir stops the virus from spreading in the body so that healing can occur faster.
- Famvir is also used for the treatment of shingles in the area around the eye or of the eye itself (ophthalmic zoster).
- 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 genital herpes infections in adults. People who have frequent episodes of genital herpes can also take Famvir to help to prevent the attacks.
2. What you need to know before you take Famvir
Do not take Famvir
- If you are allergic to famciclovir, to any of the other ingredients of this medicine (listed in section 6), or to penciclovir (the active metabolite of famciclovir and an ingredient of some other medicines).
Ask your doctor for advice, if you think you may be allergic.
Warnings and precautions
Talk to your doctor before taking 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 prevent you passing the infection on to others. You should not have sex if you have genital sores or blisters.
Other medicines and Famvir
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without prescription.
It is especially important that you tell your doctor or pharmacist if you are taking any of the following medicines:
• Raloxifen (used to prevent or treat osteoporosis).
• Probenecid (used to treat high blood levels of uric acid associated with gout and to increase blood levels of penicillin-type antibiotics), or any other medicine that can affect your kidneys.
Famvirwith food and drink
You can take Famvir with or without food.
Pregnancy, breast-feeding and fertility

Famvir is not to be used during pregnancy unless clearly necessary. Your doctor will discuss with you the potential risks of taking Famvir during pregnancy.
Famvir is not to be used during breast-feeding unless clearly necessary. Your doctor will discuss with you the possible risks of taking Famvir during breast-feeding.

3. How to take Famvir
Always take this medicine exactly as your doctor has told you. 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.

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 forget to take a dose of Famvir, you should take it as soon as you remember. Then take your next dose as scheduled. Flowever, do not take two doses within a time interval of less than 1 hour, in that case you should skip the missed dose. Furthermore, do not take a double dose to make up for a forgotten dose.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
