Experiences with
ImpetigoCheck if you have impetigo
Impetigo starts with red sores or blisters, but the redness may be harder to see in brown and black skin.
The sores or blisters quickly burst and leave crusty, golden-brown patches.
The patches can:
- look a bit like cornflakes stuck to your skin
- get bigger
- spread to other parts of your body
- be itchy
- sometimes be painful
Sores (non-bullous impetigo) or blisters (bullous impetigo) can start anywhere – but usually on exposed areas like your face and hands.
The sores or blisters burst and form crusty patches.
- might have impetigo
- had treatment for impetigo but the symptoms change or get worse
- had impetigo before and it keeps coming back
Impetigo is very infectious. Check with the GP before you go into the surgery. They may suggest a phone consultation.
Treatment for impetigo
A GP or pharmacist will check it's not something more serious, like cellulitis.
If it's impetigo, you may need:
- hydrogen peroxide cream if it's in one area
- antibiotic cream or tablets if it's more widespread
- antibiotic tablets if you have bullous impetigo or feel very unwell
Babies and people with a weakened immune system may need antibiotic tablets to stop the infection causing more serious problems.
If your impetigo keeps coming back
A GP can take a swab from your skin to check for the bacteria that causes impetigo. They may also take a swab from inside your nose.
They might prescribe an antiseptic body wash, nasal ointment, or both, to try to clear the bacteria and stop the impetigo coming back.
Do not stop taking the antibiotic tablets early, even if the impetigo starts to clear up.
Stop impetigo spreading or getting worse
Impetigo can easily spread to other parts of your body or to other people until it stops being contagious.
It stops being contagious:
- 48 hours after you start using hydrogen peroxide cream or antibiotics prescribed by your GP
- when the patches dry out and crust over (if you do not get treatment)
To help stop impetigo spreading or getting worse while it's still contagious:
stay away from school or work
keep sores, blisters and crusty patches clean and dry
cover them with loose clothing or gauze bandages
wash your hands frequently
wash flannels, sheets and towels at a high temperature
wash or wipe down toys with detergent and warm water if your children have impetigo
do not touch or scratch sores, blisters or crusty patches – this also helps stop scarring
do not have close contact with children or people with diabetes or a weakened immune system (if they're having chemotherapy, for example)
do not share flannels, sheets or towels
do not prepare food for other people
do not go to the gym
do not play contact sports like football
How to avoid impetigo
Impetigo usually infects skin that's already damaged.
To avoid spreading the infection to other areas of your body and to other people:
- keep cuts, scratches and insect bites clean – for example, by washing them with warm water and soap
- get treatment for skin conditions, like eczema
Impetigo causes sores or blisters that burst and leave crusty, golden-brown patches. They can look a bit like cornflakes stuck to your skin.
Impetigo is often treated with antibiotics. You'll need to take care not to spread the infection to other people while you have it.
You’re more likely to get impetigo if you have damaged skin from a cut, insect bite or a skin condition like eczema.
