Shingles

Also called Herpes zoster or Zoster

Shingles is an infection that causes a painful rash, usually on one side of the body. It is caused by the chickenpox virus becoming active again, often years after having chickenpox. It is more common in older people and people with a weakened immune system. You cannot catch shingles from someone, but you can catch chickenpox from someone with shingles if you have not had it.

What it is

Antiviral medicine started within 3 days of the rash can help it heal faster and reduce the risk of long-term pain. Painkillers help.

A shingles vaccine is offered to some older adults and people with weakened immune systems.

Common signs

  • A tingling or painful feeling in one area of skin before the rash
  • A rash of blotches that become itchy blisters
  • A rash on one side of the body, often the chest or tummy
  • A high temperature and feeling unwell

How it is usually diagnosed

  • Looking at the rash and asking about symptoms

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • GP notes
  • Prescriptions
  • Vaccination records

Questions to ask your doctor

  • Do I need antiviral medicine?
  • Who should I avoid while I have the rash?
  • Am I eligible for the shingles vaccine?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • A rash near the eye, or shingles with a weakened immune system: get urgent help the same day
