Impetigo is a highly contagious bacterial skin infection that commonly affects young children but can occur at any age. While not usually serious, it spreads easily through direct contact or shared items like towels and bedding. With the right treatment, impetigo typically clears up within 7 to 10 days.
Symptoms of Impetigo:
The infection starts with red sores or blisters, which may be less noticeable on brown or black skin. These quickly burst, forming distinctive golden-brown, crusty patches that can:
Look like flakes of cornflakes stuck to the skin
Increase in size and spread to other areas
Feel itchy, irritated, or painful
Impetigo commonly affects the face (around the nose and mouth), hands, and limbs but can appear anywhere on the body.
Pharmacy Treatment for Impetigo:
A pharmacist can assess symptoms and offer treatment without the need for a GP appointment. Treatment depends on the severity and type of impetigo and may include:
Hydrogen peroxide cream – An antiseptic option for mild cases affecting a small area.
Antibiotic cream – Recommended if the infection is spreading or persistent.
Oral antibiotics – Needed for widespread, severe, or bullous impetigo, or for those at higher risk (e.g. babies, people with weakened immune systems).
How Long is Impetigo Contagious?
Impetigo is highly infectious but stops being contagious:
✔ 48 hours after starting treatment (antibiotics or hydrogen peroxide cream)
✔ When sores dry out and crust over naturally (without treatment, this may take longer)
Preventing the Spread of Impetigo
Impetigo spreads through skin-to-skin contact, contaminated surfaces, and scratching the sores. To prevent spreading it to others:
Do:
✔ Wash the affected area gently with soap and water, then dry it thoroughly
✔ Wash hands frequently, especially before and after applying treatment
✔ Use separate towels, flannels, bedding, and clothing
✔ Wash infected items at a high temperature (60°C or above)
✔ Keep fingernails short and clean to prevent scratching and further spread
Don’t:
✖ Touch, scratch, or pick at sores – this can worsen the infection and cause scarring
✖ Share towels, bedding, or personal items with others
✖ Have close contact with babies, children, or people with weakened immune systems
✖ Prepare food for others while still contagious
✖ Attend school, nursery, or work until treatment has started and you are no longer infectious
How to Reduce the Risk of Impetigo in the Future
Impetigo often develops on broken or irritated skin. To reduce the risk:
✔ Keep cuts, scratches, insect bites, and eczema patches clean
✔ Avoid sharing razors, makeup, or skincare products
✔ Treat underlying skin conditions like eczema or scabies
A pharmacist can provide advice and prescribe treatment to help clear up impetigo quickly and safely.
