Shingles (cont.)

What is the treatment for shingles? Should I visit my health-care professional?
There are several effective treatments for shingles. Drugs that fight viruses (antivirals), such as acyclovir (Zovirax), valacyclovir (Valtrex), or famciclovir (Famvir), can reduce the severity and duration of the rash if started early (within 72 hours of the appearance of the rash). In addition to antiviral medication, pain medications may be needed for symptom control.

The affected area should be kept clean. Bathing is permitted, and the area can be cleansed with soap and water. Cool compresses and anti-itching lotions, such as calamine lotion, may also provide relief. An aluminum acetate solution (Burow's or Domeboro solution, available at your pharmacy) can be used to help dry up the blisters and oozing.

What are the complications of shingles?

Generally, shingles heal well and problems are few. However, on occasion, the blisters can become infected with bacteria, causing cellulitis, a bacterial infection of the skin. If this occurs, the area will become reddened, warm, firm, and tender. You might notice red streaks forming around the wound. If you notice any of these symptoms, contact your health-care professional. Antibiotics can be used to treat these complications.

A more worrisome complication occurs when shingles affect the face, specifically the forehead and nose. In this situation, it is possible, although not likely, that shingles can affect the eye, leading to loss of vision. If you have shingles on your forehead or nose, your eyes should be evaluated by a health-care professional.
