|Information for patients
Famciclovir 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 Famciclovir tablets as
soon as the first symptoms appear.
Famcilovir tablets are 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). Famciclovir tablets stop the virus from spreading in the body so that healing can occur faster.
•Famciclovir tablets are 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. Famciclovir tablets are used to treat genital herpes infections in adults. People who have frequent episodes of genital herpes can also take Famciclovir tablets to help to prevent the attacks.

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 Famciclovir tablets.

|Excess Drug Consumption
||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 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.
|Forgot Drug Consumption
||If you forget to take a dose of Famciclovir tablets, you should take it as soon as you remember. Then take your next dose as scheduled. However, 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 product, ask your doctor or pharmacist.
