Researchers found that giving older adults the vaccine reduced the expected number of later cases of shingles by half. In March 2011, the FDA extended the approval to inlcude adults 50 to 59 as well. Other treatments for postherpetic neuralgia include steroids, antidepressants, anticonvulsants (including pregabalin and gabapentin enacarbil), and topical agents.In 2006, the Food and Drug Administration approved a VZV vaccine (Zostavax) for use in people 60 and older who have had chickenpox.
Antiviral drugs may also help stave off the painful after-effects of shingles known as postherpetic neuralgia. The severity and duration of an attack of shingles can be significantly reduced by immediate treatment with antiviral drugs, which include acyclovir, valcyclovir, or famcyclovir. The viruses multiply, the tell-tale rash erupts, and the person now has shingles. When the varicella-zoster virus reactivates, the virus moves back down the long nerve fibers that extend from the sensory cell bodies to the skin.
After effects of shingles skin#
Scientists think that in the original battle with the varicella-zoster virus, some of the virus particles leave the skin blisters and move into the nervous system. Anyone who has had chickenpox is at risk for shingles. The most common location for shingles is a band, called a dermatome, spanning one side of the trunk around the waistline. Some people have mostly itching some feel pain from the gentlest touch or breeze. After several days or a week, a rash of fluid-filled blisters, similar to chickenpox, appears in one area on one side of the body. The first sign of shingles is often burning or tingling pain, or sometimes numbness or itch, in one particular location on only one side of the body. Shingles (herpes zoster) is an outbreak of rash or blisters on the skin that is caused by the same virus that causes chickenpox - the varicella-zoster virus.
