What Are Cold Sores?
Cold sores, also known as fever blisters, are small blisters that develop on the lips or around the mouth. They are caused by the herpes simplex virus (HSV-1) and are very contagious.
Cold sores typically go through five stages:
- Tingling or itching before a blister appears
- Small, fluid-filled blisters
- Oozing and crusting over of blisters
- Scabbing over of blisters
- Healing
The first outbreak usually lasts 10-14 days. Recurrent outbreaks after that are generally shorter.
What is Vicks VapoRub?
Vicks VapoRub is an over-the-counter topical ointment made by Procter & Gamble. It contains ingredients like camphor, eucalyptus oil, and menthol.
When applied to the skin, Vicks VapoRub produces a cooling, tingling sensation. It can help temporarily relieve cough and congestion when used on the chest and throat.
Because of its cooling properties, some people wonder if Vicks can help provide relief for cold sores. Here is a look at the evidence.
Can You Put Vicks on a Cold Sore?
There is no definitive scientific research on using Vicks VapoRub directly on cold sores. Therefore, doctors do not officially recommend using Vicks as a cold sore treatment.
Potential Benefits
Although untested, there are some potential benefits to putting Vicks on a cold sore:
- Cooling effect - The menthol in Vicks can temporarily numb and cool the skin, providing relief from discomfort and itching.
- Tingling distraction - The strong camphor scent and tingling sensation can distract from the pain of the cold sore blisters.
- Drying effect - The camphor may dry out oozing blisters by absorbing moisture.
Potential Risks
Despite possible benefits, there are also some notable risks to consider before putting Vicks on a cold sore:
- Skin irritation - Vicks contains harsh ingredients like camphor and eucalyptus oil that could further irritate delicate cold sores.
- Spreading infection - Applying Vicks with your fingers could introduce new bacteria and spread the herpes infection.
- Delayed healing - Certain ingredients in Vicks constrict blood vessels. This could potentially prolong healing time.
- Unpleasant burning - Menthol and camphor create a burning effect on the skin that could worsen blister pain.
Proper Usage Precautions
If you do decide to try using Vicks for a cold sore, there are some proper usage precautions to follow:
Use a Cotton Swab
Apply Vicks to the cold sore with a clean cotton swab instead of your fingers. This prevents spreading the infection to other areas.
Use Sparingly
Only use a very small amount of Vicks on the cold sore. Too much could increase skin irritation and inflammation.
Don't Use Inside Mouth
Never apply Vicks to sores inside the mouth. The ingredients are unsafe to swallow and can cause poisoning.
Stop if Irritation Occurs
Discontinue use if you notice any increased redness, swelling, or burning of the cold sore after applying Vicks. This indicates skin irritation.
Other Remedies to Soothe Cold Sores
While Vicks may help provide temporary relief, it is not a cure for cold sores. Here are some other soothing remedies you can try:
Ice Packs
Gently applying an ice pack directly to a cold sore can ease pain, swelling, and inflammation in the area.
Aloe Vera Gel
The cooling, anti-inflammatory properties of aloe vera gel can provide comforting relief for cold sore blisters when applied topically.
Petroleum Jelly
Dabbing petroleum jelly onto cold sores creates a protective barrier to prevent cracking and keep the area moisturized as it heals.
Licorice Root Cream
Creams with licorice root extract can decrease swelling and redness when applied to cold sores.
Medical Treatments for Cold Sores
For best results, consider using medicated cold sore treatments recommended by your doctor or pharmacist:
Antiviral Medications
Oral antiviral drugs like acyclovir or valacyclovir can speed up healing time and reduce symptoms if taken at the first sign of a cold sore outbreak.
Antiviral Creams
Topical antiviral creams containing acyclovir or penciclovir applied directly to cold sores can hasten the healing process.
Anesthetic Creams
Over-the-counter creams like Orajel or Zilactin with benzocaine can provide temporary numbness and pain relief on cold sores.
Talk to your doctor about prescription-strength treatments if your cold sores are severe or frequent.
Preventing Future Cold Sore Outbreaks
While Vicks likely does not cure or prevent cold sores, you can reduce future outbreaks through lifestyle measures like:
- Using SPF lip balm when outdoors
- Taking L-lysine supplements
- Managing stress levels
- Avoiding excessive sun exposure
- Not sharing food/drinks
- Keeping your immune system healthy
See your doctor if your cold sores are very painful or recurring frequently for proper diagnosis and treatment options.
