Treating Cold Sores or Fever Blisters
A cold sore or fever blister is a highly contagious infection caused by the herpes simplex virus. It's important to treat cold sores and fever blisters as soon as you notice them, so that you can help prevent spreading the virus to other areas of your skin or other people.
Steps for Treating Cold Sores or Fever Blisters
- Wash your hands with warm water and soap. Do this often, and whenever you touch the cold sore.
- If you have recurrent outbreaks, start taking antiviral medication as soon as you notice any signs of a cold sore or fever blister.
- Consider applying lip balm or petroleum jelly with an SPF of 30 or more to the spot before you go out in the sun, as exposure to sunlight can make outbreaks worse.
- Take steps to reduce stress, which can trigger an outbreak. Try yoga, deep breathing, meditation, or physical activity.
- Once the blisters have broken, apply an over-the-counter ointment to keep the area moist and to help the healing process. Popular options include Abreva, Cinnacain, and Campho-Phenique.
- If your symptoms are severe, contact your doctor. He or she may prescribe an oral or topical antiviral medication.
By properly treating cold sores and fever blisters, you can help reduce the duration of the outbreak and lessen the chance of spreading the virus.
