- 1). Press ice against the spot for several minutes as soon as you feel or see the beginnings of a cold sore. Not only does ice numb the uncomfortable tingling of a cold sore, but it may result in a less severe outbreak.
- 2). Apply Abreva, a cold sore cream, directly to your sore. Abreva is the only cream the FDA says will shorten the duration of a cold sore, but other topical creams and gels can be used for pain relief.
- 3). Take 15 mg of zinc a day until the sore is healed. Zinc fortifies your immune system and blocks the virus from replicating and making a bigger sore.
- 4). Take 1,200 to 3,000 mg of lysine, an amino acid that supports healthy mouth tissue. Do this daily until the sore is completely healed.
- 5). Squeeze fresh lemon into a full glass of fresh water. Drink five to eight glasses of water a day, adding lemon when you can. Lemon can help limit the reproduction of the virus.
- 6). Use a cotton swab to dab petroleum jelly onto the sore when it begins to get dry. This will help healing and relieves some of the discomfort of cracked lips.
