Infected Eczema

Additional information

Infected eczema

Infected eczema can feel like regular eczema that’s suddenly levelled up: more sore, more weepy, more crusty, and a lot more stressful. This page explains what infected eczema is, what causes it, what treatments are used in the UK, and when you should get urgent help. We’ll also cover how courierpharmacy.co.uk can support you with safe, discreet care.

Overview

Infected eczema is eczema (atopic dermatitis or another eczema type) where the skin has developed a secondary infection. Eczema already weakens the skin barrier and changes the immune response, which makes it easier for bacteria, viruses, or fungi to cause trouble. [3]

It matters because infection can:

• Make symptoms much worse (pain, oozing, crusting)

• Delay healing

• Spread to other areas

• Occasionally cause serious illness, especially with viral infections like eczema herpeticum. [3], [5]

It also affects daily life in very real ways: sleep gets wrecked, clothes rub, showers sting, and people feel self-conscious. Add in the fear of “is this getting dangerous?” and it’s a lot to carry.

Diagnosing infected eczema can be tricky because eczema can look inflamed even without infection. That’s why we focus on pattern changes: sudden worsening, weeping, crusting, pain, and feeling unwell. [2]

What is infected eczema?

• weeping or oozing
• yellow or golden crusting
• pus-filled spots
• more pain or tenderness
• fast worsening redness and irritation
• sometimes fever or feeling unwell

Brief overview of support/services offered by Courier Pharmacy

At courierpharmacy.co.uk, we support people with eczema flares that may be infected by helping you:

• Understand the difference between a flare and an infection

• Know when self-care is enough and when you need treatment

• Choose the right type of topical treatment (and avoid the wrong one)

• Build a simple routine that protects your skin barrier

If you’ve had repeated infections, we can also help you think through common triggers (scratching, stress, sweating, harsh soaps, and under-treated eczema) and how to reduce the risk of the next flare. [1], [2]

When you should go to a doctor

If your eczema is blistered, crusty, leaking fluid, has pus-filled spots, or is painful, you should get urgent advice from a GP or NHS 111. [2]

If you feel unwell with fever, chills, or rapidly spreading redness, don’t wait it out. Infections can worsen quickly, especially in children and people with widespread eczema. [2]

What you should know about infected eczema treatments

Treatments depend on what’s causing the infection:

• Bacterial infection: may need topical or oral antibiotics, plus continued eczema control. [1], [2], [4]

• Viral infection (eczema herpeticum): needs urgent antiviral treatment and same-day assessment. [3], [5], [6]

• Fungal infection: may need antifungal treatment, especially in skin folds. [7]

A key point from UK guidance is that not every flare needs antibiotics. Sometimes the main issue is uncontrolled inflammation and broken skin, which lets germs move in. Getting the eczema under control is part of treating the infection, not a separate job.

How common is infected eczema?

Eczema itself is common, affecting a significant proportion of children and a smaller proportion of adults worldwide. [8] Infection is also common in eczema, especially bacterial infection with Staphylococcus aureus, which is frequently found on eczema skin and is linked with flares and complications.

Viral infections are less common, but they can be more serious. Eczema herpeticum is a key one to know about because it can become severe without prompt antiviral treatment. [3], [5]

What causes infected eczema?

Infected eczema happens when three things line up:

• The skin barrier is damaged (dryness, cracks, scratching)

• The immune response in the skin is altered

• Germs get a chance to multiply

Bacteria such as Staphylococcus aureus can attach more easily to eczema skin and may worsen inflammation through toxins and immune effects. [9]

Viruses can also infect eczema skin. Eczema herpeticum is caused by herpes simplex virus and can spread quickly across areas of eczema. [3], [5]

Fungal involvement is sometimes seen, especially in certain body areas and in some people with atopic dermatitis, where yeast may play a role.

What happens in the body with infected eczema?

Eczema involves inflammation and a weakened skin barrier. When the barrier is leaky, irritants and microbes get in more easily. The immune system responds, but in eczema it can be “misdirected”, which leads to ongoing inflammation and itch. [10]

Scratching then causes micro-tears. That creates a perfect environment for infection. Once bacteria or viruses multiply, they can:

• Increase inflammation

• Cause oozing and crusting

• Trigger pain and swelling

• Spread to nearby skin

In some cases, infection can lead to systemic symptoms like fever and malaise, which is a sign you need prompt medical review.

Diagnosing infected eczema

Diagnosis is usually clinical, based on symptoms and how the rash looks. Key clues include weeping, crusting, pustules, rapidly worsening eczema, and systemic symptoms like fever. [3]

A clinician may take a swab if:

• Infection keeps coming back

• Treatment isn’t working

• There’s concern about resistant bacteria

For suspected eczema herpeticum, the priority is urgent assessment and treatment rather than waiting for test results.

Managing infected eczema: current treatments

Treatment depends on severity and suspected cause.

For suspected bacterial infection, UK guidance covers the use of antibiotics when clinically indicated, alongside ongoing eczema management (emollients and anti-inflammatory treatment as appropriate)

For suspected eczema herpeticum, urgent antiviral therapy is recommended because delays can increase complications.

For suspected fungal involvement, antifungal treatment may be used, especially in skin folds where yeast thrives.

Non-medicine support matters too:

• Keep nails short to reduce skin damage

• Use bland emollients often to support the barrier

• Avoid fragranced washes and harsh soaps

• Use cool compresses for itch (and to reduce scratching)

Patient experiences and challenges

A lot of people feel judged for scratching. But itch is a symptom, not a personality flaw. When you’re half-asleep and your skin feels like it’s buzzing, scratching is almost automatic.

Common challenges include:

• Not knowing if it’s a flare or an infection

• Worry about using steroid creams safely

• Embarrassment about visible crusting or weeping

• Sleep disruption and low mood

A good plan is realistic. It should fit normal life, not a fantasy life where you never sweat, never stress, and always remember to moisturise.

Personalised care

At Courier Pharmacy we advocate prevention in addition to treatment, so we recommend the following:

• Early recognition of infection signs

• Clear step-up/step-down plans for flares

• Barrier-first routines that reduce repeated infections

• Support for trigger patterns (sweat, friction, detergents)

Research is ongoing into the skin microbiome and how bacterial balance affects eczema severity and relapse. [4], [9]

Looking to the future

The future is hopeful. We’re learning more about why eczema skin is prone to infection and how to reduce that risk. Better education, better routines, and better targeted treatments can reduce the “flare ? scratch ? infect ? repeat” cycle.

FAQs

What does infected eczema look like?

It often looks more wet and crusty than a usual flare, with weeping, yellow crusts, pustules, and increased pain.

How do I know if my eczema is infected or just flaring?

A flare is usually dry, red, and itchy. Infection is more likely if it’s weeping, crusting, painful, rapidly worsening, or you feel unwell.

Can I treat infected eczema at home?

Mild flares can be supported with emollients and trigger control. But if you suspect infection, especially with weeping, crusting, pus, or pain, get medical advice.

When should I seek urgent help for infected eczema?

Seek urgent help if your eczema is blistered, crusty, leaking fluid, painful, or you feel unwell. Eczema herpeticum symptoms need same-day assessment.

What is eczema herpeticum?

It’s a herpes simplex virus infection on eczema skin. It can cause painful blisters and systemic symptoms and is considered a medical emergency.

Will I always need antibiotics for infected eczema?

Not always. Treatment depends on severity and cause. Some flares look infected but are mainly inflammation. A clinician can help decide what’s appropriate.

Can steroid creams make infection worse?

Steroids reduce inflammation, but if there’s an untreated infection, symptoms can worsen or spread. That’s why assessment matters when infection is suspected.

How can I prevent infected eczema?

Moisturise often, treat flares early, avoid triggers, keep nails short, and reduce scratching where possible. Barrier care is prevention.

Is infected eczema contagious?

The eczema itself isn’t contagious. Some infections (like herpes simplex) can spread through close contact, so it’s important to get assessed if viral infection is suspected.

How can courierpharmacy.co.uk help with infected eczema?
