Eczema flare-ups can cause intense itching, dry skin, redness and discomfort that interfere with sleep and everyday life. Understanding common eczema triggers and knowing which NHS treatments are available can help you manage symptoms and reduce the frequency of flare-ups.
In the UK, atopic eczema is a common long-term skin condition that can affect children and adults. Although there is no permanent cure, appropriate skincare, prescribed treatments and trigger management can help keep symptoms under control.
This guide explains what causes eczema flare-ups, how to recognise worsening symptoms, which NHS treatment options may help and when to seek medical advice.
What is an eczema flare-up?
An eczema flare-up occurs when eczema symptoms become worse than usual. The skin may become increasingly dry, itchy, inflamed or cracked, sometimes following exposure to an irritant, an allergen or another trigger.
Atopic eczema is associated with a weakened skin barrier, which makes it harder for the skin to retain moisture and protect itself from irritants. Inflammation can then contribute to further itching and scratching.
Common symptoms include:
- Dry, sensitive or scaly skin.
- Persistent itching, particularly at night.
- Red or inflamed patches on lighter skin.
- Purple, brown, grey or darker patches on darker skin.
- Cracked skin that may become sore or bleed.
- Thickened skin following repeated scratching.
- Occasionally, weeping or crusting when inflammation is severe or infection develops.
Eczema can affect the hands, face, neck, elbows, knees and other areas. Its appearance varies depending on skin tone, age and the type of eczema.
What triggers eczema flare-ups?
Eczema triggers vary from person to person. Identifying your own triggers can help you reduce avoidable irritation without unnecessarily restricting your everyday activities.
1. Soaps, detergents and skincare products
Harsh soaps, fragranced body washes, cleaning products and some cosmetics can irritate sensitive skin. Frequent handwashing and exposure to household cleaning products may also aggravate hand eczema.
What can help: Choose fragrance-free cleansers and moisturisers, use lukewarm water and apply an emollient after washing. Wear suitable protective gloves when handling cleaning products, while avoiding prolonged sweating inside gloves.
2. Cold weather, dry air and central heating
Cold weather, low humidity and indoor heating can dry out the skin, making eczema symptoms worse. Sudden changes in temperature may also trigger itching.
What can help: Apply moisturiser regularly, avoid overheating rooms and choose soft clothing that does not irritate the skin.
3. Heat, sweating and exercise
Sweat can irritate eczema-prone skin, particularly when it remains on the body after exercise. Overheating may also increase itching.
What can help: Wear breathable clothing, keep your environment comfortably cool and rinse off sweat after exercise. Apply moisturiser afterwards.
4. Stress and poor sleep
Stress does not cause every eczema flare-up, but it can worsen itching and contribute to a cycle of scratching, disturbed sleep and further inflammation.
What can help: Maintain a consistent sleep routine and explore relaxation techniques. If stress is significantly affecting your wellbeing, speak to your GP.

5. Allergens and environmental irritants
Some people notice worsening symptoms after contact with particular substances, including certain metals, fragrances or occupational chemicals. Dust mites, pollen and animal allergens may be relevant for some individuals, but they are not universal eczema triggers.
What can help: Keep a symptom diary to identify consistent patterns. Avoid expensive allergy testing or restrictive diets unless a healthcare professional recommends an appropriate assessment.
6. Scratching and skin damage
Scratching may provide temporary relief, but it damages the skin barrier and increases inflammation. Broken skin can also become infected.
What can help: Keep fingernails short, use prescribed treatments as directed and apply suitable moisturisers frequently. A cool compress may temporarily ease itching.
7. Hormonal changes and other individual factors
Some people report eczema changes during hormonal fluctuations, illness or periods of disrupted sleep. However, these factors do not affect everyone in the same way.
If flare-ups are persistent, severe or difficult to explain, a GP can assess your symptoms and discuss possible contributing factors.
NHS treatment options for eczema flare-ups
The NHS offers several approaches to eczema management. Treatment depends on the severity of symptoms, the affected body area, your age and whether complications such as infection are present.
1. Emollients: the foundation of eczema care
Emollients are moisturising treatments that help soften the skin, reduce water loss and support the skin barrier. They are commonly recommended for regular use, even when eczema appears to have settled.
Available forms include:
- Creams for everyday moisturising.
- Ointments for very dry or thickened skin.
- Lotions for less dry or hair-bearing areas.
- Soap substitutes for washing.
A pharmacist or GP can help you choose a suitable product. Apply emollients regularly and according to the product instructions, particularly after washing.
Important: Emollients containing paraffin can make clothing, bedding and dressings more flammable. Keep treated fabrics away from cigarettes, naked flames and other ignition sources. Bath and shower surfaces may also become slippery.
2. Topical corticosteroid creams and ointments
Topical corticosteroids, commonly called steroid creams, reduce inflammation during eczema flare-ups. They are available in different strengths and are selected according to the severity of eczema and the body area being treated.
A GP or other qualified prescriber may recommend:
- Mild steroids for suitable mild cases and sensitive areas.
- Moderate or stronger preparations for selected more severe flare-ups.
- A defined treatment course with instructions on where and how often to apply the medicine.
Use the prescribed product as directed. Facial skin, eyelids, skin folds and children’s skin often require particular care when choosing steroid strength and duration.
If eczema repeatedly returns, ask your clinician whether a maintenance treatment plan is appropriate rather than repeatedly self-treating without review.
3. Calcineurin inhibitors and other prescription treatments
For certain patients, a clinician may recommend topical calcineurin inhibitors, such as tacrolimus or pimecrolimus. These can be useful in selected cases, particularly where avoiding repeated corticosteroid use on sensitive areas is important.
Other treatments may be considered when standard topical therapy does not adequately control eczema. Their suitability depends on the diagnosis, severity and individual circumstances.
Do not start prescription treatments without appropriate medical advice.
4. Wet-wrap therapy for selected cases
Wet-wrap therapy involves applying prescribed topical treatment or moisturiser and covering the affected skin with suitable damp and dry layers. It can sometimes help manage severe flare-ups, but it is not appropriate for everyone.
Seek guidance from a healthcare professional before using wet wraps, particularly if steroid medicines are involved, because covering treated skin can increase absorption.
5. Specialist dermatology treatment
If eczema is severe, widespread or resistant to appropriate treatment, your GP may refer you to an NHS dermatology service.
Depending on the circumstances, specialist options may include phototherapy, systemic medicines or newer targeted treatments. These are generally considered when simpler treatments are insufficient or the disease has a substantial impact on quality of life.
Antibiotics are not routinely needed for eczema itself. They may be prescribed when a clinician identifies a bacterial infection and determines that antibiotic treatment is appropriate.
How to manage an eczema flare-up at home
A consistent routine can help reduce irritation and support prescribed treatment.
1. Moisturise regularly
Apply a suitable emollient several times daily as needed and follow your treatment plan. Use a clean spoon or pump where appropriate to avoid contaminating the product.
2. Wash gently
Use lukewarm water and an emollient soap substitute. Avoid harsh scrubbing, strongly fragranced products and very hot showers.
3. Reduce friction and overheating
Choose comfortable fabrics, avoid excessive heat and change out of sweaty clothing promptly.
4. Track possible triggers
Record flare-up dates, products used, weather conditions and any recurring exposures. Look for consistent patterns instead of assuming that every suspected trigger is responsible.
Avoid scratching as much as possible, but do not blame yourself if itching is difficult to control. If home care is not helping, seek advice rather than allowing symptoms to continue unchecked.
When should you contact your GP about eczema?
Contact your GP if:
- Your eczema is worsening or is not responding to recommended treatment.
- Itching is disrupting sleep or everyday activities.
- The skin is repeatedly cracking, bleeding or becoming painful.
- You need advice about steroid strength, duration or alternative medicines.
- You suspect a contact allergy or are unsure whether the rash is eczema.
- The condition is affecting your mental wellbeing or quality of life.
If you need help understanding other skin conditions, read HealthCresto’s guides to psoriasis treatment in the UK and adult acne. These conditions can sometimes be confused with other rashes, but they may require different treatments.
When is eczema urgent?
Seek urgent medical advice through your GP or NHS 111 if your eczema becomes suddenly worse, develops increasing pain, produces pus or develops extensive crusting, or if you develop a fever or feel generally unwell.
Get urgent same-day medical assessment if you suspect eczema herpeticum. Warning signs include rapidly worsening, painful eczema with clusters of blisters or similar-sized punched-out sores, sometimes accompanied by fever or feeling unwell. This can be a serious viral infection requiring prompt treatment.
Call 999 or attend A&E for a life-threatening emergency.
Does the NHS provide free eczema treatment?
NHS GP consultations and clinically appropriate NHS treatment are generally available without a consultation fee, subject to eligibility and the usual NHS arrangements. Prescription charges depend on where you live and the applicable rules.
In England, NHS prescription charges may apply unless you qualify for an exemption or another scheme. NHS prescriptions are free in Scotland, Wales and Northern Ireland under their respective arrangements.
Not every moisturiser or skincare product is routinely prescribed. Prescribing policies can vary by local NHS guidance and clinical need, so ask your pharmacist or GP which options are suitable.
Frequently asked questions about eczema flare-ups
1. What is the most common trigger for eczema flare-ups?
There is no single trigger for everyone. Common aggravating factors include soaps, detergents, dry weather, overheating, sweating and scratching. Identifying personal patterns can help you manage symptoms.
2. How can I calm an eczema flare-up quickly?
Use a suitable emollient frequently, avoid known irritants, keep the skin comfortably cool and follow any prescribed flare-up treatment. If symptoms are severe, painful or rapidly worsening, seek medical advice.
3. Can a GP prescribe steroid cream for eczema?
Yes. A GP or another qualified prescriber can recommend an appropriate topical corticosteroid based on the severity of eczema, the affected area and your individual circumstances.
4. Are eczema creams available on the NHS?
Yes. Clinically appropriate emollients and prescription eczema treatments may be available through the NHS. Whether a particular product is prescribed depends on clinical need and local prescribing policies.
5. Should I avoid certain foods if I have eczema?
Not automatically. Food allergies can be relevant in some cases, particularly in children, but eliminating foods without a clear reason can cause nutritional problems. Speak to a healthcare professional before starting a restrictive diet.
6. Is eczema contagious?
No. Atopic eczema is not contagious and cannot be passed from one person to another through ordinary contact. However, broken eczema skin can develop a separate infection that may need treatment.
7. When should I see a dermatologist for eczema?
A GP may refer you to an NHS dermatologist if eczema is severe, persistent, diagnostically uncertain or not responding to appropriate treatment. Referral depends on clinical need and local NHS pathways.
8. Can eczema be cured permanently?
There is currently no permanent cure for atopic eczema, but many people can manage it effectively with regular moisturising, suitable prescribed treatment and trigger management. Symptoms may improve or fluctuate over time.
Conclusion
Eczema flare-ups can be uncomfortable and frustrating, but identifying personal triggers and following an appropriate treatment plan can make symptoms more manageable. Regular emollient use, avoiding irritating products and using prescribed anti-inflammatory treatments correctly are important parts of care.
If your eczema keeps returning, affects your sleep or becomes painful, speak to your GP about reviewing your treatment. Seek urgent assessment if you develop signs of infection or rapidly worsening symptoms.
