More than 150 million Americans experience the
pain, discomfort, and embarrassment associated
with cold sores. Cold sores, also called fever
blisters, are primarily caused by the herpes simplex virus 1.
The herpes simplex virus 2 is typically responsible for genital
herpes, although both virus types can cause cold sores
or genital herpes. The virus is highly contagious and can be
easily spread from one individual to another by both direct
and indirect contact. It is important for you to thoroughly
understand how to treat a cold sore outbreak and how to
prevent or reduce the chance of further complications.
What Can Cause a Cold Sore Outbreak?
There is no cure yet for the cold sore virusfrom the
time of infection on, you will have periods when
the virus is not active and periods when you will
have an outbreak of cold sores. Certain situations
called risk factors can increase the chances that
you will have an outbreak.
Common triggers for cold sore outbreaks are as
follows:
- Stress/fatigue
- Ultraviolet radiation/extreme exposure to the sun
- Exposure to cold weather
- Fever and upper respiratory infections
- Trauma due to recent dental work
- Infectious diseases
- Menstruation or other hormonal changes
- Factors that may compromise the immune
system (chemotherapy, immunosuppressant
agents)
- Certain foods such as chocolate and others
with a high content of the amino acid arginine
What Are the Signs and Symptoms of Cold
Sores?
Cold sores usually appear on your lips or in adjacent
areas around your lips and sometimes on your nose.
You may first feel pain and tingling 1 or 2 days before a
cold sore forms. Some people may also experience
mouth soreness, fever, or swelling of lymph glands. Cold
sores appear as small raised blisters filled with a clear
fluid and can cause redness in the affected area as well
as pain and discomfort. In general, cold sores heal in 10
to 14 days.
How Are Cold Sores Spread?
If you have a cold sore, it is very easy to infect another
person through direct contact, such as kissing. It can
also be spread if a person touches the cold sore and
touches any mucous membranes, such as your nose,
eyes, and mouth. If you touch your cold sore, always
wash your hands with warm soapy water. Infection may
also occur through indirect contact with the virus such
as by sharing personal items such as razors or drinking
out of the same glass.
Treatments for Cold Sores
A cure for cold sores has not been found, but many
treatment options are available. You can discuss these
options with your pharmacist or primary health care
provider to determine which one is best for you. For
example, if you have many outbreaks of cold sores, your
doctor may prescribe a prescription product for the treatment
of cold sores.
A New Product
A new product has recently entered the market as a
treatment for cold sores. It is called RELEEV 1-Day Cold
Sore Symptom Treatment. RELEEV is designed to aid
healing and reduce the duration of an outbreak. RELEEV
has been shown to relieve the symptoms of cold sores,
including pain, itching, tingling, burning, and throbbing
within 24 hours of initial use. RELEEV is a topical microbicide
that is a proprietary blend of benzalkonium chloride
0.13% and phytochemicals primarily derived from
the Asteraceae family. RELEEV is a nontoxic botanical
product and should be applied 3 to 4 times a day. It can
be used safely in adults and children 2 years of age or
older and is nonirritating. It is best used at the first sign
of an outbreak but can be applied at any time to relieve
symptoms. It may be used as an antiseptic to help
cleanse or dry cold sores and to help in preventing secondary
infections. RELEEV also may be used on sores on
the inside of the lips and on oral mucosa. RELEEV should
not be used if an individual has an allergy to the
Asteraceae (daisy) family of flowers.
Other Products
Another nonprescription topical product available for
the treatment of cold sores is Abreva. In addition, a variety
of medications are available to help with the discomfort
and pain associated with cold sores. These products
include skin protectants such as lip balms and moisturizers
that provide protection for the lip area. Other products
can provide relief of pain and burning. Examples of these
products include Blistex, Campho-Phenique, and Zilactin.
Preventing and Managing Cold Sore Outbreaks
The virus that is responsible for cold sores is very contagious.
To reduce or prevent cold sore recurrences and to
prevent the spread of cold sores to others, you should
take the following steps:
- Avoid sharing items such as towels, razors, and eating
utensils.
- Avoid close or direct contact with others when cold
sores are present.
- Avoid things that may trigger cold sores, such as
stress, fatigue, and excess sun exposure.
- Clean cold sores with warm water and a nonprotein
soap frequently, and keep them dry.
- Avoid touching cold sores to reduce the chance of
spreading them to other parts of your body.
- Wash your hands frequently and thoroughly to help
prevent the spread of cold sores.
- Use topical skin protectants to prevent infection in
cold sores that can result from drying and cracking.
- Use lip balm or moisturizers to keep the lips moist.
- Avoid foods high in the amino acid arginine such as
chocolate during an outbreak.
- Avoid drinking alcoholic beverages, because they
may hinder the immune system from fighting the
outbreak.
When to Seek Medical Advice
Consult your physician if:
- Cold sores do not heal within 1 to 2 weeks or worsen.
- You experience frequent episodes of cold sores
(more than 6 per year).
- You have any health conditions affecting your
immune system.
- Your cold sore shows signs of secondary infection,
such as unusual redness, swelling, or discolored
discharge.
