Impetigo is one of the most common skin infections seen across the UK, especially in children. It spreads fast, looks alarming, and can be confused with other skin conditions. Yet many people wait too long before getting help.

If you or your child has crusty sores, blistering skin, or a spreading rash, knowing what to do and when to act can make a real difference. This guide covers everything you need to know about impetigo treatment UK options, what the warning signs mean, and how Chertsey Pharmacy can help you manage it quickly and safely.

What Is Impetigo and Why Does It Spread So Fast?

Impetigo is a highly contagious bacterial skin infection. It is caused by two types of bacteria: Staphylococcus aureus and Streptococcus pyogenes. These bacteria enter the skin through small cuts, insect bites, or broken skin from conditions like eczema.

It spreads through direct contact with an infected person or by touching contaminated surfaces such as towels, clothing, or bedding. In schools, nurseries, and sports clubs, outbreaks can move quickly through groups.

There are two main types:

Non-bullous impetigo is the most common form. It causes small red sores that burst and leave a honey-coloured crust, usually around the nose and mouth.

Bullous impetigo is less common but more serious. It produces larger fluid-filled blisters that burst and leave a yellow, crusty patch. It affects the trunk, arms, and legs more often than the face.

Both types need prompt treatment to prevent spreading to others and to avoid complications.

Early Signs of Impetigo You Should Not Ignore

Catching impetigo early is the best way to keep it from spreading and to shorten recovery time. Here are the signs that need your attention:

Sores Around the Nose and Mouth

Red sores that appear quickly around the nose and mouth are a classic early sign. They may look minor at first but burst within days, leaving a thick, golden-brown crust. Do not mistake this for dry skin or a cold sore.

Fluid-Filled Blisters on the Body

Blisters that appear on the chest, back, or limbs and fill with cloudy fluid suggest bullous impetigo. These can be painless initially, which means people often delay seeking help. If blisters are spreading, that is a clear signal to act.

Itching and Skin Irritation

The affected area is usually itchy. Scratching spreads bacteria to other parts of the body and to other people. If a child is scratching a crusty sore, treat it as impetigo until a professional confirms otherwise.

Rapid Spread to Other Skin Areas

If you notice new sores appearing in areas that were previously clear, the infection is spreading. Impetigo can move quickly, especially in warm weather or in people with compromised skin barriers.

Swollen Lymph Nodes

Swollen glands near the infected area, such as under the jaw or in the neck, suggest the body is fighting infection. This sign often means the infection is more established and needs medical assessment.

High Temperature or Feeling Unwell

Fever alongside a skin rash should not be dismissed. While impetigo itself rarely causes fever, a high temperature can indicate a secondary infection or a complication like cellulitis that needs urgent care.

Impetigo Treatment UK: Your Main Options

In the UK, impetigo treatment follows NHS guidelines and depends on how severe the infection is and how widely it has spread.

Topical Antibiotic Cream (Mild Cases)

For small, localised patches, a topical antibiotic such as hydrogen peroxide 1% cream (Crystacide) or fusidic acid cream is usually the first-line treatment. Fusidic acid is prescription-only in the UK.

Since the introduction of the Pharmacy First scheme in 2024, pharmacists can now assess and supply prescription-strength treatments for impetigo without needing a GP appointment first. This has significantly cut waiting times for people needing fast access to impetigo treatment UK-wide.

Oral Antibiotics (More Widespread Cases)

When impetigo has spread across several areas, is not responding to topical treatment, or affects a person who is immunocompromised, oral antibiotics such as flucloxacillin or cefalexin are prescribed. These are typically taken for five to seven days.

Self-Care Alongside Treatment

Antibiotics treat the bacteria, but good hygiene reduces reinfection and spread. Key steps include:

• Wash sores gently with warm soapy water and pat dry with a clean cloth
• Cover the affected area loosely with a dressing
• Wash hands regularly, especially before and after touching the infected area
• Keep infected children away from school or nursery until 48 hours after starting antibiotic treatment or until all sores have crusted over
• Avoid sharing towels, flannels, and bedding

When to See a Pharmacist vs When to See a GP

Many cases of impetigo can now be handled at a pharmacy, which saves time and gets treatment started faster.

See a pharmacist if:

• Sores are limited to a small area
• The person is otherwise well with no fever
• There are no signs of a spreading deeper infection
• You want a quick professional assessment before calling the GP

See a GP or call 111 if:

• The infection is spreading rapidly despite treatment
• There is high fever, significant pain, or the person is very unwell
• There are signs of cellulitis (skin that is hot, swollen, and red beyond the sores)
• The person is immunocompromised or has a chronic condition
• Impetigo keeps coming back

Go to A&E if:

• An infant under three months develops skin sores
• There are signs of a serious systemic infection such as confusion, rapid breathing, or extreme weakness

Complications of Untreated Impetigo

Most people recover fully with treatment. But leaving impetigo untreated or undertreated can lead to complications.

Cellulitis is a bacterial skin infection that spreads into deeper layers of skin and tissue. It causes redness, swelling, warmth, and pain. It needs oral or intravenous antibiotics.

Scarlet fever can occasionally follow a streptococcal skin infection. Symptoms include a widespread pink-red rash, sore throat, and fever.

Post-streptococcal glomerulonephritis is a rare complication affecting the kidneys. It can occur after a streptococcal impetigo infection and causes blood in the urine, swelling, and raised blood pressure. It requires immediate medical care.

Antibiotic resistance is a growing concern. Overuse of topical antibiotics like fusidic acid has led to resistant strains of bacteria in some areas. Using the correct treatment for the correct duration and following pharmacist advice properly is important.

Impetigo in Children: What Parents Need to Know

Children aged two to five are most commonly affected, and school-age children are also at high risk. It is not a sign of poor hygiene. Impetigo can affect any child who comes into contact with the bacteria.

Keep these points in mind:

• Children should stay off school or nursery until 48 hours after starting antibiotics or until all sores have crusted and dried
• Inform the school so other parents can watch for symptoms
• Cut children’s fingernails short to reduce scratching and spreading
• Wash children’s bedding and clothing at a high temperature
• Do not let siblings share face cloths or towels with an infected child

If a child keeps getting repeat impetigo infections, it may be worth discussing with a healthcare professional whether there is an underlying skin condition such as eczema that is providing a route for bacteria to enter.

Impetigo in Adults: Different But Still Common

Adults can get impetigo too, though it is less common. It tends to occur in people who already have a skin condition, who play contact sports, or who work in settings like healthcare or childcare.

Adults who are immunocompromised, such as those on chemotherapy or immunosuppressants, are at higher risk of developing more severe infections and should seek assessment sooner rather than later.

Preventing Impetigo From Spreading at Home

If one person in your household has impetigo, taking steps to contain it matters.

• Assign that person their own towel, flannel, and pillowcase
• Wash all laundry at 60°C or higher

Frequently Asked Questions About Impetigo Treatment UK

Q: Can I get impetigo treatment in the UK without a GP appointment?

Yes. Since the NHS Pharmacy First scheme launched in 2024, pharmacists across England can assess impetigo and supply prescription topical antibiotic treatment directly. Visit your local pharmacy, including Chertsey Pharmacy, for a same-day assessment.

Q: How long does impetigo take to clear up with treatment?

Most cases clear up within seven to ten days of starting antibiotic treatment. Without treatment, it can last two to three weeks or longer and risks spreading further.

Q: Is impetigo contagious after I start antibiotics?

Yes, but much less so. You are generally considered non-contagious 48 hours after starting antibiotic treatment, provided sores are covered and you are following hygiene advice.

Q: Can impetigo come back after it is treated?

Yes, particularly in children with underlying skin conditions like eczema. Treating the underlying condition and maintaining good skin hygiene reduces the risk of recurrence.

Q: What does impetigo look like at the start?

It usually begins as small red spots or blisters around the nose, mouth, or broken skin. These burst within a few days and form a distinctive honey-colored or golden-brown crust.
