Chemists Own Famciclovir (Favic) is an antiviral medicine used to treat recurrent outbreaks of cold sores in adults who have a normal immune system. Favic does not cure the viral infection, however it helps relieve the symptoms and shortens the duration of an outbreak.

Cold sores usually begin on or around the lips, mouth, and nose as small red bumps that turn into fluid-filled blisters that can be tender and 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.

Cold sores can be unpredictable. The virus can become active again in the body, even after many years, resulting in recurrent outbreaks.

For best results, start the medicine as soon as possible after the onset of symptoms of a cold sore, such as tingling, itching or burning, or the appearance of the first signs, such as redness or swelling. This is when the virus is reproducing rapidly.

Ingredients:

Favic 500 contains 500 mg of famciclovir.

Usage Directions:

Follow all directions given to you by your pharmacist or doctor carefully. 

If you do not understand the instructions on the label, ask your pharmacist or doctor for help.

Take Favic (Famciclovir) as soon as possible after the first symptoms (e.g., tingling, itching or burning) or signs (e.g., redness or swelling) of a cold sore appear.

Do not take the tablets if a hard crust has already formed on the cold sore.

The usual dose is three 500 mg tablets taken together as a single dose.

However, if you have problems with your kidneys and your pharmacist has referred you to your doctor to see if this medicine is suitable for you, your doctor may have recommended a different dose.
