Herpes labialis

Cold sore; Fever blister; Herpes simplex - oral; Oral herpes simplex

Untreated, the symptoms will generally go away in 1 to 2 weeks. Antiviral medications taken by mouth may shorten the course of the symptoms and decrease pain.

Herpes sores often come back again and again. The antiviral medicines work best if you take them when the virus is just starting to come back -- before you see any sores. If the virus returns frequently, your doctor may recommend that you take the medicines all the time.

Wash blisters gently with soap and water to reduce the spread of the virus to other areas of skin. An antiseptic soap may be recommended. Applying ice or warmth to the area may reduce pain.

Herpes labialis usually disappears spontaneously in 1 to 2 weeks. It may recur. Infection may be severe and dangerous if it occurs in or near the eye, or if it happens in immunosuppressed people.
