How to Treat a Cold Sore

Cold sores or fever blisters that form around the mouth are caused by the herpes simplex virus type 1. The sores are filled with fluid and may open up and crust over during an outbreak. Once the virus that causes cold sores is in your body, you cannot eradicate it, but you can treat the discomfort of cold sores as they heal.

Step 1

Apply a compress to your cold sore to relieve some of the pain. Some people prefer a warm compress while others find cold takes the pain away. Moisten a soft washcloth with either warm or cold water. Wash the cloth after use to prevent the spread of the virus.

Step 2

Take medication to dull the pain and tingling you may feel when you have a cold sore. Over-the-counter drugs like ibuprofen and acetaminophen are effective. Consult your doctor if you do not find relief with these medications.

Step 3

Use a topical medication that contains an anesthetic such as lidocaine. Apply the ointment or cream directly to the cold sore. Pharmacies and grocery stores carry a selection of over-the-counter remedies of this kind. Dosage instructions are included in the packaging.

Step 4

Ask your doctor to prescribe an anti-viral drug for you to take as soon as you know you are having a cold sore outbreak. Some people feel tingling even before the sore appears. Anti-viral medicines do not cure the herpes simplex virus but can minimize symptoms.

Tips and Warnings

  • Refrain from popping or scratching the fever blister or you may risk spreading the virus to other areas of your body or to other people. Allow the sore to heal on its own. Avoid kissing someone who has an active cold sore or you may end up becoming infected yourself. Keep towels, bedding and eating utensils separate while someone in your home has an active fever blister.
