WEDNESDAY, March 5, 2014 (HealthDay News) -- People older than 50 can reduce their risk for developing shingles by being vaccinated against the varicella-zoster virus that causes the painful condition, an expert says.
"People who have had shingles previously can still receive the vaccine. If you are above the age of 50 years old, you should talk to your health care provider about the shingles vaccines," advised Dr. Khalilah Babino, immediate care physician at Loyola University Health System.
Shingles is caused by the same virus responsible for chicken pox. Most people who get shingles are older than 50 because the virus can remain dormant in the body for years before being activated again, according to background information in a university news release.
Anyone who develops shingles on their face should seek immediate medical attention since this could result in vision loss, advised Babino, who is also an assistant professor in the department of family medicine at Loyola University Chicago Stritch School of Medicine.
"If you are diagnosed with shingles, you are contagious as long as you have blisters and ulcers," Babino said in the news release. "Since it can be spread from person to person it is important to cover your rash and wash your hands frequently. It also is important to avoid people who have not received the chicken pox vaccine, pregnant women and anyone with a weak immune system."
"Fortunately, there is antiviral medication to treat shingles," Babino noted. "The medication does not kill the virus like antibiotics kill bacteria, but they help slow the virus and speed recovery. . . I recommend starting these medications within 72 hours of the onset of rash. Since shingles can be very painful, you might also need prescription pain medication."
Although most people with shingles don't develop any complications from the virus, there is a 10 percent chance of developing a painful nerve condition known as postherpetic neuralgia, which can last for up to a year, the news release noted.
