Try to avoid triggers that can cause cold sore outbreaks
• Keep your lips moisturized
• Wear sunblock on your lips and avoid long exposure to the sun
• Live a healthy lifestyle: eat right, exercise, get plenty of sleep, and avoid stress
Treat cold sore symptoms with an over-the-counter medication
Carmex® Multi-Symptom Cold Sore Treatment contains benzocaine, an FDA-approved pain relief ingredient, which helps temporarily relieve pain and itch associated with cold sores and fever blisters.
Consider a prescription medication for cold sores
There is no cure for cold sores. Your dentist or physician might recommend a prescription antiviral medication as a cold sore remedy to treat fever blisters. Antiviral treatments can help your body fight the virus.
