About Remedies for Fever Blisters

Fever blisters, also called cold sores, are caused by a strain of the herpes simplex virus. The virus normally lies dormant in the body for long periods. When it becomes active, it causes blisters to form around the mouth. Remedies for fever blisters include antiviral medications, topical treatments, over-the-counter pain relievers and home-care measures. The goal of these remedies is to ease pain and discomfort. Some remedies may reduce the duration of the outbreak, but only slightly.

  1. Time Frame

    • According to the Mayo Clinic, fever blisters usually clear up without treatment in seven to 10 days. Oral antiviral medications may slightly shorten the duration.

    Antiviral Medications

    • Antiviral medications are often used to treat fever blisters. Taken orally, they may shorten the duration of an outbreak of blisters and decrease pain and discomfort. Antiviral creams applied directly to the blisters may also help relieve pain. Antiviral medications are only effective if taken when the virus first appears. If fever blisters keep coming back, which they often do, your doctor may recommend that you take antiviral medication on a regular basis.

    Topical Treatments

    • Over-the-counter topical treatments, such as creams or lip balms, can be used to help ease discomfort associated with fever blisters. Two of the most common are topical lidocaine and benzyl alcohol (Zilactin).

    Pain Relievers

    • Other remedies for fever blisters include over-the-counter pain relievers. The most common include aspirin, ibuprofen (such as Advil and Motrin) and acetaminophen (Tylenol). However, you should not give aspirin to children because of potentially serious side effects.

    Home Remedies

    • There are several home remedies for fever blisters. Wash the blisters gently with soap and water to keep them from spreading to other areas. Your doctor may recommend an antiseptic soap. Apply ice or warmth to the blisters to ease discomfort. Try to keep from touching the infected area, and do not pinch, pick or squeeze the blisters.
