How to Get Rid of a Fever Blister in a Day

By Kathryn Milner ; Updated July 27, 2017

Developing a fever blister can be discomforting when attending social events or working in the general public. These pus-filled mini-blisters occur when the herpes simplex virus 1 invades the body through close skin-to-skin contact or by sharing facial products. Fever blisters generally develop inside or outside the mouth, often near the lips,and can take as long as one to two weeks to heal. Natural treatments for fever blisters are available, and you can drastically reduce a fever blister’s appearance in as little as one day.

Salty Toothpaste

Pour 1 tsp. of non-gel toothpaste and 1/2 tbsp. of salt into a bowl. Stir the ingredients for two minutes to properly blend.

Dip one cotton swab into the salty toothpaste and apply to fever blister. Be sure to coat the entire fever blister with the mixture. Salt contains anti-inflammatory properties that minimize redness and swelling while extracting the pus-like liquid from fever blisters. Sodium lauryl sulfate, an active ingredient in non-gel toothpastes, robs the herpes simplex virus proteins of adequate food, resulting in fever-blister elimination.

Allow the salty toothpaste to soak on the fever blister overnight for best results. Repeat treatment once daily as needed.

Tea Time

Soak 1 black-tea bag in cool running water. Squeeze the tea bag over the sink to remove excess liquid.

Apply the moistened tea bag directly onto the fever blister. Tea contains anti-viral agents such as tannic acid that can help the body's defense system eliminate the herpes simplex virus.

Allow the tea bag to soak on the fever blister for 15 minutes. Rinse your face with cool water to remove leftover tea drippings. Repeat this treatment two times daily for best results.

Tips

All ingredients can be purchased at your local supermarket.

Over-the-counter medications such as Abreva are available for fever-blister treatment; however, they often produce unwanted side effects and require a minimum of three days before showing signs of improvement.

Fever Blisters cannot fully heal until the pus-like fluid is extracted from the blister. The toothpaste salt remedy will drain all fluid from the fever blister in one day, producing only a tiny scab. Be patient and allow the scab to properly heal.

To help speed a fever blister's healing time apply ice. Wrap 1 individual ice cube in a paper towel and place onto fever blister. Ice can slow a fever blister’s development and numb the skin surrounding the blister for instant pain relief. Apply ice every hour for 10 to 15 minutes daily until fever blister heals.

Warnings

Consult your physician immediately if fever blisters worsen, cause your face to swell or do not heal within two weeks. While fever blisters are very common and affect nearly 75 percent of the world's population, they can be a symptom of a serious medical condition. Refrain from using salty toothpaste remedy if your skin is very sensitive.
