How do I manage eczema flares and prevent complications?

Question

Hello doctor,

I am a 40-year-old woman with long-standing eczema that sometimes becomes red, swollen, and painful. My doctor said infections can happen, but I do not fully understand why eczema makes me more prone to skin infections.

How can I tell the difference between a flare-up and an infection?
Are antibiotics often needed?
How can I prevent complications?
Should I see a dermatologist immediately when symptoms change?

Kindly help.

Hello,

Welcome to icliniq.com.

I understand how worrying it can be when eczema flares become red, swollen, or painful. Let me explain in simple terms. Eczema weakens the skin’s natural protective barrier, making it more vulnerable to bacteria, viruses, and fungi. This is why people with eczema are more prone to skin infections.

A normal flare-up usually causes dryness, redness, itching, and scaling, while an infection may present with increased redness, swelling, warmth, pain, pus, or yellow crusts, and sometimes fever.

Antibiotics are not needed for every flare, only if there is a confirmed bacterial infection, usually diagnosed by a dermatologist. Viral infections like herpes can also complicate eczema and need different treatment.

To prevent complications from eczema, it is important to:

Keep the skin well moisturized, which helps strengthen the natural skin barrier and reduce dryness.
Avoid scratching, as scratching can introduce bacteria and increase the risk of infection.
Use gentle, fragrance-free cleansers to protect sensitive skin from irritation.
Treat eczema flares promptly with topical medications as advised by your doctor to control inflammation, reduce itching, and prevent the skin from becoming more damaged or infected.

Regarding lifestyle changes, I would suggest the following:

Shift to 100 percent cotton clothing and bed fabric, as cotton does not trigger eczema, while other fabrics like plastic or wool can trigger eczema.
Avoid perfume in your skin care and body care products, as perfume can also trigger eczema.
Avoid possible food allergens like nuts or dairy if you notice they trigger your flare.
Avoid carpets and pets in your house, as these can also be possible triggers of eczema.

Switch to ceramic base moisturizers, non-comedogenic make-up, and use physical sunscreen like Zinc oxide rather than mineral sunscreen.

You should see a dermatologist immediately if you notice sudden redness, swelling, pain, oozing, or crusting, or if your symptoms worsen beyond your usual flare. Early treatment can prevent infections from spreading and reduce the risk of scarring or long-term skin damage.

With careful skin care, prompt flare management, and attention to signs of infection, most eczema complications can be prevented, keeping your skin healthier and more comfortable.
