Get urgent medical advice (urgent GP appointment / NHS 111) if your eczema is blistered, crusty, leaking fluid, has pus-filled spots, is painful, swollen or warm, suddenly gets worse or spreads, or you have a high temperature / feel generally unwell. These can be signs your eczema is infected or a more serious condition such as eczema herpeticum.

What “infected eczema” means

“Infected eczema” usually means eczema skin has developed a secondary infection. Eczema-prone skin has a weakened barrier, and scratching can create tiny breaks that allow germs to enter more easily.

Infections in eczema can be:

Bacterial (common; often causes weeping/crusting/pus and rapid worsening), or
Viral, including eczema herpeticum (urgent), which involves blistering and systemic symptoms in some cases.

Signs your eczema may be infected (bacterial infection signs)

Infection can be obvious-crusting, weeping, swelling, redness, pain, pus-but sometimes the clue is simply that eczema isn’t improving as expected.

Common signs (use this as a recognition list)

Rapidly worsening eczema (flare that escalates fast)
Weeping/leaking fluid
Crusting (often yellow/golden, “stuck-on” crust)
Pus-filled spots/blisters
Skin becomes painful (not just itchy)
Skin feels hot/warm or looks more swollen than usual
Fever or feeling generally unwell
No response to usual eczema treatment (emollients + topical steroids)

If multiple signs appear together (especially pain + warmth + fever), treat it as urgent.

When to suspect eczema herpeticum (same-day urgent)

Eczema herpeticum is a serious viral infection that can affect people with eczema and needs prompt treatment.

Red flags for herpeticum

Clusters of blisters that are painful (often similar-looking “grouped” blisters)
Rapid spread over days, sometimes with new patches appearing
Feeling unwell with fever and swollen lymph nodes
Any concern about eye-area involvement

If this pattern is possible, don’t wait-seek same-day urgent medical advice.

“When steroids aren’t enough” – what that really means

Topical steroids reduce inflammation, which is why they help eczema flares. But if infection is driving the flare, you may need additional treatment (such as antibiotics for bacterial infection or antivirals for eczema herpeticum).

Important clinical principle (this prevents confusion)

NICE guidance for secondary bacterial infection says to manage the underlying eczema and flares with emollients and topical corticosteroids whether antibiotics are offered or not. In other words: infection management often happens alongside eczema management, not instead of it.

So “steroids aren’t enough” usually means one of these:

Infection is present and needs antimicrobial treatment too.
The trigger/exposure is ongoing (e.g., hand irritants) so the flare keeps restarting.
The diagnosis may not be purely eczema (overlap with contact dermatitis or another condition).

What to do right now (step-by-step)

If you think eczema may be infected, use this sequence:

Step 1: Check for urgent signs

If you have any of the NHS urgent signs (crusting/weeping/pus, pain/warmth/swelling, rapid worsening/spreading, fever/unwell), seek urgent advice

Step 2: If blisters + rapid worsening, treat as same-day urgent

Because eczema herpeticum can worsen quickly, seek same-day assessment if blister clusters + fever/unwellness are present.

Step 3: Keep the routine simple (don’t add noise)

Avoid starting new fragranced skincare or experimenting with multiple new products during a suspected infection.
Continue basic barrier support (moisturising) unless a clinician tells you otherwise-dryness and cracking worsen the barrier.

Step 4: Reduce spread and skin damage

Don’t share towels/cloths; keep nails short; minimise scratching.
Take a clear photo now (and again 12–24 hours later) to show progression.

Where your treatment hub fits

Once infection risk is assessed, your treatment pathway can be chosen from the main hub:

For mild anti-inflammatory options when appropriate and guided, your category includes:

If infection is suspected, don’t rely on a product page alone-use the hub pathway and clinician guidance first.

Preventing repeat infections (practical prevention layer)

Because infections are more likely when the barrier is broken:

Keep moisturising consistent to reduce cracking and micro-breaks.
Treat flares early (less scratching = fewer entry points).
Identify hand/cleaning irritants if hands are repeatedly affected.
Use a “simple routine” during flares less irritation, better barrier stability.

If your eczema frequently becomes crusty/weeping or you’re getting repeated infections, that’s a strong reason to get a structured review and a prevention plan.
