What EZOVIR® Cold Sore Relief is used for
EZOVIR® Cold Sore Relief is an antiviral medicine that is used to treat recurrent outbreaks of cold sores in adults who have a normal
immune system (the body system which fights against harmful bacteria, viruses and fungi).
Cold sores are an infection caused by a virus called herpes simplex type I (HSV-1). Cold sores usually begin on or around
the lips, mouth, and nose. After redness and swelling develop, the small red bumps turn into fluid-filled blisters.
The blisters may weep or burst and this can be tender and painful. A shallow ulcer and yellow crust form as the cold sore
dries. The crust eventually falls off, exposing new pink-coloured skin. Generally the sores heal without scarring.
The infection is most commonly acquired as a baby or child from physical contact with parents or relatives that have a cold
sore, often by kissing. After the initial infection has healed, the virus becomes dormant in nerve cells.
Cold sores can be unpredictable. Even after many years, some people may experience recurring cold sores due to viral reactivation.
Some common triggers to a cold sore may include:
dry chapped lips
Many people who get cold sores know when one is coming by a tingling, burning, itchy or painful sensation or redness in the
area. This can happen very rapidly.
Although EZOVIR® Cold Sore Relief does not cure the viral infection, it helps to relieve the symptoms and shorten their duration of an outbreak.
The best results are obtained if the medicine is started as soon as possible after the onset of symptoms occur. These may
include tingling, itching or burning, or the appearance of the first signs, such as redness or swelling. This is when the
virus is reproducing rapidly.
Ask your pharmacist or doctor if you have any questions about why this medicine has been prescribed for you.
EZOVIR® Cold Sore Relief is only available from your pharmacist. The cold sores pack may be purchased without a doctor's prescription.
It is not addictive.
Use in Children
This medicine is not recommended for use in infants, children or adolescents under 18 years of age.

A single dose of EZOVIR® Cold Sore Relief is all that is necessary for treating each episode of cold sores. Each pack of EZOVIR® Cold Sore Relief contains enough medicine for one dose. A repeat dose during this episode is not recommended.

Tell your pharmacist or doctor if your cold sore symptoms do not improve within a few days, or if they become worse.
If you become pregnant, tell your doctor before taking any further doses of this medicine to another episode of cold sores.
Your doctor can discuss with you the risks of taking it while you are pregnant.

Be careful driving, operating machinery or doing jobs that require you to be alert until you know how EZOVIR® Cold Sore Relief affects you.

Things that may help your condition
Cold sores are contagious and the virus can be passed on from an infected person to an uninfected person through close physical
contact or saliva, even when blisters are not present.
The risk is much higher when the cold sore is visible, as the virus can be shed, making it easy to infect other people.
Take the following precautions to avoid spreading the virus:
Keep the areas affected by the virus as clean and dry as possible.
Avoid touching or scratching the sore areas as you may spread the virus on your fingers.
Do not share any objects that have been in contact with a cold sore (e.g. drinking glasses, eating utensils, or towels).
Avoid direct skin-to-skin contact of the area with other people (e.g. kissing) until the cold sore has healed.
Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking EZOVIR® Cold Sore Relief.
