Bullous pemphigoid

Bullous pemphigoid is a rare skin condition that causes itching, redness and blisters. It may last a few years and sometimes causes serious problems, but treatment can help.

Check if you have bullous pemphigoid

Bullous pemphigoid mainly affects people over 60.

Large red, blotchy, dry rash with small scabs on the arm of a person with white skin — It usually starts as sore, itchy red patches

Lots of sore, red patches with small blisters spread on white skin spread across a woman's chest — It can affect large areas of the body or limbs

Large red, flaky, dry rash with scabs and a small orange blister on white skin — After a few weeks, small blisters may appear

A large orange blister and a smaller, dark blister on the wrist of a person with white skin — The blisters can grow quite big and may contain blood

Not everyone gets blisters. If you do, they may keep coming and going for months or years.

There are several other causes of blisters if you're not sure it's bullous pemphigoid.

Non-urgent advice: See a GP if:

you have an itchy red rash that doesn't go away in a few weeks
you have lots of blisters, or big, painful blisters
you have blisters that keep coming back
your skin is red, hot and swollen, or a blister is filled with green or yellow pus

A GP can check what the cause might be.

If they think it could be bullous pemphigoid, they may refer you to a specialist for tests and treatment.

Treatment for bullous pemphigoid

Bullous pemphigoid eventually goes away on its own, but it can last a few years.

Treatment can help your skin heal, stop new patches or blisters appearing, and reduce the risk of your skin getting infected.

The main treatments are:

Your skin should eventually heal without scarring, but it might be a bit darker than it was before.

Important

Do not burst your blisters – your skin might get infected.

If a blister is in an annoying place (like the bottom of your foot), your doctor can drain it with a needle.
