Fever blisters, also known as cold sores, are painful blisters that can develop on or around the lips. They are caused by the herpes simplex virus (HSV) and usually go away on their own. However, if you want to get rid of them quickly, you may consider using alcohol to dry them out. While some people swear by rubbing alcohol as a remedy for cold sores, there is no scientific data to support its effectiveness. In fact, it can irritate the skin, cause a burning sensation, and even lead to contact dermatitis. It is recommended to apply alcohol before the blisters appear to reduce their severity and avoid using it once the cold sore has developed into a blister. Other treatments for cold sores include over-the-counter medications, topical ointments, and antiviral drugs.

What You'll Learn
Apply alcohol before blisters appear to reduce their severity
Cold sores, also known as fever blisters, are painful blisters that can develop on or around the lips. They are caused by the herpes simplex virus (HSV). While there is no cure for HSV, medication can be used to manage symptoms and speed up the healing process.
Applying alcohol to a cold sore is a common remedy. Alcohol is a drying agent found in some over-the-counter cold sore preparations. The belief is that applying pure alcohol to a cold sore will dry the sore and promote healing. However, it's important to note that rubbing alcohol can cause contact dermatitis, resulting in a slight burning sensation and inflamed red skin. It can also irritate the sore and the surrounding skin, increase pain, and even cause reinfection.
To avoid these risks, it is recommended to apply alcohol to the affected area before the blisters appear to reduce their severity. At this stage, you can apply rubbing alcohol or topical ointments to the area to reduce the symptoms and help suppress the HSV virus. Applying alcohol before the blisters form can also help reduce the sore's size and severity.
If you choose to apply alcohol to the affected area, it is important to do so with caution. Stop using it immediately if it causes more irritation or pain. It is also important to note that once the blisters have appeared, do not apply rubbing alcohol or any other harsh treatment. Instead, you can use petroleum jelly, lemon balm, or another gentle cream to reduce discomfort and help the blisters dry out and heal faster.

Avoid alcohol once blisters have formed
While some people use rubbing alcohol on fever blisters, it is not recommended once the blister has formed. Rubbing alcohol is a combination of isopropyl alcohol and water and is often used as an antiseptic agent. It can help a fever blister dry up quickly, but it can also irritate the skin around the sore, increasing pain and even causing reinfection.
Fever blisters, also known as cold sores, are small, fluid-filled blisters that develop on or around the lips, chin, or cheeks. They are caused by the herpes simplex virus (HSV) and can be very painful, causing itching and a burning sensation. While there is no cure for HSV, medication is available to manage symptoms and speed up the healing process.
Once the blisters have formed, it is best to avoid using rubbing alcohol and opt for other treatments instead. Over-the-counter cold sore ointments can help shorten an outbreak. Applying a cool, damp cloth to the sore can help reduce redness and crusting, aiding in faster healing. Natural remedies such as lemon balm and a cream containing rhubarb and sage can also help decrease pain and promote quicker healing.
To prevent future outbreaks, it is important to avoid common triggers such as stress, hormonal changes, illness, and physical strain. Taking care of your lips with a sunblock lip balm can also help, especially when exposed to sunlight or dealing with dry, cracked lips. Additionally, replacing your toothbrush after a cold sore is crucial, as the virus can live on your toothbrush for days and lead to reinfection.

Alcohol can irritate the skin and cause reinfection
While some people believe that applying alcohol to a fever blister can help dry it out and promote healing, there are risks associated with this practice. Alcohol is known to irritate the skin and can cause contact dermatitis, characterised by a slight burning sensation and inflamed red skin. This is particularly true for rubbing alcohol, which is included in some over-the-counter cold sore preparations.
Additionally, alcohol can irritate the skin and cause reinfection. Alcohol is associated with an increased risk of infections, and heavy drinking can slow down the body's ability to ward off infections for up to 24 hours. Alcohol misuse can weaken the immune system, making the body more susceptible to diseases and infections. It can also cause a "leaky gut," allowing toxins and bacteria to enter the body and increasing the risk of endotoxemia and colorectal cancer.
Furthermore, alcohol can disrupt the intestinal permeability, leading to bacterial translocation and high levels of endotoxins in the circulation. This can induce the production of inflammatory cells, contributing to conditions such as alcoholic liver disease. Alcohol can also damage the epithelial lining of the gastrointestinal tract, causing inflammation and increasing the risk of gastroesophageal reflux disease and oral cavity cancer.
The use of alcohol on fever blisters may also lead to reinfection by transferring bacteria to the affected area. It is important to note that the herpes simplex virus type 1, which causes cold sores, can live on surfaces like a contaminated toothbrush, and using it can lead to reinfection. Therefore, it is recommended to replace your toothbrush after a cold sore outbreak.

Alcohol is a drying agent found in some over-the-counter cold sore treatments
While some people advocate for the use of rubbing alcohol on cold sores, it is generally not recommended due to the risk of skin irritation. Rubbing alcohol can cause a burning sensation, red and inflamed skin, and even reinfection. It is best to avoid using it once the cold sore has developed into a blister. Instead, it is suggested to apply it to the affected area before the blisters appear to reduce their size, severity, and symptoms.
If you decide to use rubbing alcohol on a fever blister, it is important to be cautious. Discontinue use immediately if you experience any irritation, pain, or discomfort. It is also crucial not to touch or pick at the cold sore, as this can spread the infection.
To effectively manage cold sores, it is recommended to consult a healthcare professional. They can prescribe antiviral medications or suggest over-the-counter treatments that contain menthol, tea tree oil, or antibacterial agents to reduce discomfort and speed up healing. Additionally, keeping a cool, damp cloth against the sore and using ice packs can help reduce redness and swelling.

Other remedies include ice, cold packs, and lemon balm
While some people use rubbing alcohol to dry out fever blisters, it can irritate the skin and cause a burning sensation. It may even lead to contact dermatitis. Hence, it is best to avoid using it, especially once the blister has formed.
Other remedies that can be used to dry out fever blisters include ice, cold packs, and lemon balm. When applied at the first sign of a tingling sensation, ice can help reduce the pain and severity of a fever blister. It can also prevent a full-blown blister from developing. However, it is important to remember not to apply ice directly to the skin, but to wrap it in a cloth first before applying it to the lesion.
Cold packs or compresses can also be used to soothe the pain and discomfort associated with fever blisters. They help reduce swelling, redness, and discolouration. Additionally, they can ease inflammation and remove crusty areas. Reusable gel ice packs or homemade cold compresses made by placing ice in a plastic bag and wrapping it in a cloth can be used for this purpose.
Lemon balm is another effective remedy for fever blisters. It can be applied topically as a cream directly to the lesion to reduce irritation and improve its appearance. Lemon balm leaf can also be soaked in boiling water, cooled, and then applied directly to the lesion several times a day using a cotton swab. Lemon balm helps speed up the healing process and can be continued for a few days even after the sores have healed.
