3. Possible mild side effects are nausea, vomiting, diarrhea, itching, insomnia, and light skin rash.

4. Possible severe side effects are a severe rash or an anaphylactic allergic reaction (leading to the inability to breathe and subsequent death if not treated rapidly).

WHAT ARE THE SYMPTOMS OF SHINGLES?

The symptoms of Shingle (Herpes Zoster) are usually described as a burning or tingling sensation before the rash occurs. The rash usually has a red base. On top of the base there is usually fluid filled vesicles. There is no pus, unless there is secondary infection. The rash is usually in lines because the rash is following the path of one or several nerves in the same area of the body—but only on one side of the body. It is most commonly seen on the back, chest, and abdomen—but it can be anywhere, including the eyes and ears, which can be very bad places for infection because it can cause permanent hearing loss or sight loss. It is almost always on one side of the body.

WHAT IS THE CAUSE OF SHINGLES (HERPES ZOSTER)?

The cause of Shingles is the reactivation of the Chicken Pox virus. The virus is called the Varicella-Zoster Virus. People who have never had Chicken Pox can not get shingles—but they can get Chicken Pox (which can be more dangerous when it is acquired by and adult—rather than during childhood). The reason that Shingles only occurs in one location on the body is not known.

HOW IS HERPES ZOSTER (SHINGLES) DIAGNOSED?

Shingles is usually diagnosed by a careful history and visual inspection of the skin. A laboratory test can be performed to confirm the diagnosis if desired. The test is made by swabbing a leaking vesicle and sending the specimen to the lab.
