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 as soon as the first symptoms appear.
How Famciclovir works
Famciclovir is used to treat cold sores (herpes labialis) of the lips in adults. Cold sores are an infection caused by a virus called herpes simplex type 1. Cold sores usually begin on or around the lips, as small red bumps that turn into fluid-filled blisters. Cold sores can be tender or painful. Many people who get cold sores know when one is coming by a tingling, burning, itchy or painful sensation or redness in the area.
- If you are allergic (hypersensitive) to famciclovir, to any of the other ingredients of Famciclovir 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.
- If you have kidney problems (or have had them before), please refer to your doctor who may recommend you another treatment.
- 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 Famciclovir.
