If you are over 50, shingles is one health problem worth knowing about now. For some people shingles looks like something as simple as tingling, itching, or burning skin that is manageable. For others, shingles progresses to a painful, blistering rash moving onto severe pain and complications that hang around long after the rash disappears.
This article will help you understand the simple definition of shingles, along with the early signs of this viral infection, how to manage an outbreak, plus news about the Shingrix vaccine and when you should seek medical attention.
Another interesting bit of information is that scientists are discovering potential benefits associated with the shingles vaccine that go beyond preventing the infection itself. More about that further down in this article.
First, What Is Shingles?
Shingles, medically known as herpes zoster, is caused by the varicella-zoster virus, the same virus responsible for chickenpox.
If you had chickenpox as a child, and then got better, the virus never completely left your body. Instead, it became an inactive virus hiding out in your nerve tissue. Years or even decades later, it can reactivate and travel along a nerve and up to the skin, causing shingles.
The risk increases with age as the immune system naturally changes. That’s one reason shingles becomes particularly important to consider after age 50.
A typical shingles rash develops on one side of the body or face, forming a stripe or band. Pain, burning, itching or tingling can begin several days before the rash appears. Fluid-filled blisters then develop and eventually scab over. Other shingles symptoms may include headache, fever, chills, fatigue and an upset stomach.
Early Signs of Shingles: Don't Miss the 72-Hour Window
One of the most important things to know about treating shingles is that timing matters.
Prescription antiviral medications such as acyclovir, valacyclovir and famciclovir can shorten the duration and severity of shingles but must be taken within 72 hours after the shingles rash appears.
This means that you shouldn’t be keeping an eye on a rash for a week to see if it improves.
If you suddenly develop unexplained burning, tingling or pain followed by a blistering rash, particularly if it appears predominantly on one side of your body, seek medical care promptly.
Are There Different Levels of Shingles?
There aren’t official levels of shingles in the way we might describe stages of some other illnesses. However, there is a big difference between an uncomplicated localized case and shingles that requires more urgent medical attention.
Localized shingles is the most familiar form of the disease. The rash and pain generally follow a nerve pathway on one side of the torso or another limited area of the body.
A more painful or extensive outbreak may involve a larger area and cause significant nerve pain, fatigue and difficulty sleeping or performing everyday activities.
Shingles on the face or around the eye requires prompt medical attention. When shingles affects nerves involving the eye, it can threaten vision. Ear or facial involvement can also sometimes affect hearing, balance or facial movement.
Disseminated shingles occurs when the rash becomes widespread rather than remaining in its typical localized pattern. It is more likely in people with weakened immune systems and requires prompt medical evaluation. Rare neurological complications can also occur, including inflammation involving the brain or nervous system.
One of the most common longer-term complications is postherpetic neuralgia (PHN). With PHN, nerve pain continues after the rash has healed and may last for months or longer. The risk of this complication increases with age.
What Can You Do at Home for Shingles?
Medical treatment and home care often work together. If a healthcare provider prescribes an antiviral, take it exactly as directed and complete the recommended course.
At home, keep the rash clean and dry and avoid scratching or picking at blisters. Cool, damp compresses can help soothe irritated skin. Loose-fitting, soft clothing can reduce friction, and adequate rest can help your body recover sooner.
Over-the-counter pain medications may be appropriate for some people but ask your healthcare provider or pharmacist if you have kidney disease, stomach ulcers, take blood thinners or have other conditions or medications that could make common pain relievers unsafe.
FACT: Shingles itself isn’t passed from one person to another in the same way a cold is. However, varicella-zoster virus from shingles blisters can cause chickenpox in someone who has never had chickenpox or the chickenpox vaccine.
Until the blisters have crusted, cover the rash, when possible, wash your hands frequently and avoid direct contact with pregnant people without evidence of immunity, newborns, immunocompromised individuals and people who have never had chickenpox or the chickenpox vaccine.
Shingles Prevention After 50: Shingrix
Vaccination has dramatically changed our ability to prevent shingles. The current shingles vaccine, Shingrix, is a recombinant, adjuvanted vaccine (this is an immunization that combines a genetically engineered piece of a germ with an immune-boosting chemical additive to create strong protection). Unlike the older Zostavax vaccine, it does not contain live varicella-zoster virus.
The FDA has designated Shingrix for preventing shingles in adults 50 and older. It is also for adults 18 and older who are at increased risk because of immunodeficiency or immunosuppression.
For most adults 50 and older, the recommended series consists of two doses. Clinical trials found very high efficacy against shingles, including approximately 97% efficacy in adults ages 50 to 69 and about 91% in adults 70 and older.
NOTE: You should still discuss vaccination with your healthcare provider even if you’ve already had shingles. Having an outbreak doesn’t guarantee that you won’t get shingles again.
Emerging Shingles Vaccine Research
Shingles research has become especially interesting lately because scientists are investigating whether shingles vaccination might have benefits extending beyond preventing a painful rash.
A 2026 study published in Nature Communications examined more than 329,000 vaccinated and matched unvaccinated adults. Among adults 65 and older, receiving two doses of the recombinant zoster vaccine was associated with a significantly lower risk of dementia.
Researchers attempted to account for what is known as the “healthy vaccinee” effect, where people who choose vaccination may also engage in other health-promoting behaviors.
The results add to previous research. A 2025 Nature study took advantage of an unusual vaccine eligibility policy in Wales that created what researchers call a natural experiment. It found that receiving the older shingles vaccine was associated with about a 20% relative reduction in new dementia diagnoses over seven years.
More research is needed to determine exactly why this association exists and whether shingles vaccination itself directly prevents or delays dementia.
The story doesn’t end with brain health.
Another study examined recombinant shingles vaccination and cardiovascular outcomes. Researchers found that people receiving the recombinant vaccine had a lower risk of major cardiovascular events compared with those receiving the older live vaccine.
These results are exciting, but they require perspective. Researchers have not established that Shingrix should be used as a treatment or preventive therapy for dementia or cardiovascular disease. Further studies, including clinical trials, are needed to determine whether these associations represent additional direct benefits of vaccination and, if so, why they occur.
For now, the primary reason to get a Shingrix vaccine is to prevent shingles and its potentially painful complications.
When to Seek Medical Help for Shingles
Because antiviral treatment works best when started early, consider seeking medical care as soon as you suspect shingles rather than waiting for the rash to become severe.
Prompt evaluation is especially important when the rash is on the face, near an eye or ear, unusually widespread or extremely painful. You should also seek medical attention if you have a weakened immune system, develop a high fever, experience severe headache, confusion, weakness or other neurological symptoms, or if the affected skin becomes increasingly red, swollen, warm or produces drainage that could indicate a secondary bacterial infection.
Eye symptoms, vision changes, significant facial weakness, confusion or other severe neurological symptoms may require emergency evaluation.
Remember, the first 72 hours after the rash appears are especially important because early antiviral treatment can help reduce the severity and duration of an outbreak.
