Medications

• Aveeno Advanced Relief Cold Sore Treatment, Zenmed AvaCare, Valtrex, Viroxyn, Zilactin and Denavir are just some of the prescription and over-the-counter products out there. Consult your doctor or a pharmacist for a recommendation. Topical lidocaine or benzyl alcohol may also provide some relief.
  
  

Natural Remedies

• Natural remedies can be used, as well. Lemon balm, peppermint oil, tea tree oil and echinacea have been used to alleviate symptoms and duration times.
  
  

Lifestyle Changes

• Identify triggers and sources of stress that cause the cold-sore episodes, and avoid these situations as much as you can. Avoiding peas, peanuts, gelatin, chocolate, beer and cola drinks is also helpful in reducing the number of episodes.
  
  

Ice

• Apply ice when you first feel the pain and tingling sensation that accompanies cold sores to lessen the severity of the sore.
  
  

Zinc

• Apply zinc directly to the area to prevent the virus from reproducing and lessen the symptoms.
  
  

Lysine

• Lysine in the form of foods, supplements or ointments can lessen the duration and severity of symptoms. Potatoes and dairy products fall into this category.
