Difference Between Urticaria and Eczema

Urticaria and eczema are both common skin conditions, but they have distinct characteristics. Here are the definitions followed by the difference between the two:





Also known as hives, it's a skin rash with raised, itchy bumps.

A chronic skin condition characterized by dry, itchy skin and inflammation.


Allergic reactions, infections, medications, and stress.

Allergens, irritants, genetic factors, and environmental triggers.


Red or skin-colored welts or bumps that appear suddenly and may disappear quickly.

Dry, inflamed skin with redness, swelling, and sometimes blisters or crusts.


Often intensely itchy.

Can be itchy but not always as severe as in urticaria.


Typically acute and lasts for a few hours to days.

Can be chronic and last for weeks to months.


Foods, medications, insect bites, stress, and infections.

Allergens (like pollen, pet dander), irritants (like soaps), stress, and climate changes.


Bumps can appear anywhere on the body and may move around.

Commonly occurs in the bends of elbows, behind knees, on face, neck, and hands.


Typically individual welts or hives.

Skin patches, sometimes with oozing, crusting, or scaling.


Antihistamines, corticosteroids, avoiding triggers.

Moisturizers, topical corticosteroids, antihistamines, and avoiding triggers.

What is Urticaria?

Urticaria, often known as hives, is an allergic reaction in which swollen, itchy welts appear on the skin. These welts emerge unexpectedly and can shift from one location to another, lasting anywhere from an hour to a few days. Allergens, medicines, infections, and stress are all potential triggers.

Key Features of Urticaria:

  • Wheals, or raised, red, itchy welts, are the defining feature of urticaria. These welts can arise anywhere on the body and come in various sizes and shapes.
  • Unlike eczema, urticarial welts often appear and go fast, lasting minutes to hours. They may vanish entirely, leaving no trace.
  • Urticaria can be caused by a variety of reasons, including allergies (food and medicine), infections, physical stimulation (pressure, heat, cold), and even mental stress.
  • Urticaria can be acute (less than 6 weeks) or chronic (greater than 6 weeks). In chronic situations, determining the underlying reason might be difficult.

What is Eczema?

Eczema is a chronic inflammatory skin ailment that results in dry, itchy, and irritated skin. It usually shows as red, scaly spots and can occasionally ooze or crust. Eczema is caused by a breakdown in the skin's barrier and can be brought on by irritants, allergies, or even dry weather.

Key Features of Eczema:

  • Eczema is characterised by dry, itchy skin that can turn red, inflammatory, or cracked. It frequently triggers a scratching cycle, exacerbating the disease.
  • Eczema is a persistent, inflammatory skin disorder that flares up on occasion. Unlike urticaria, eczema symptoms can last for days or weeks.
  • In children, eczema often affects the face, hands, and inner elbows, but adults may suffer it in flexural regions (knees, elbows), hands, or feet. The location varies according to the type of eczema.
  • Irritating agents (soaps, detergents), allergens (dust mites, pollen), and environmental variables (dry weather) can all cause eczema flares. It is frequently related with a family history of allergies or atopic dermatitis.

Similarities Between Urticaria and Eczema

  • Both conditions are characterised by extreme itching, which can be debilitating and cause scratching, perhaps exacerbating the symptoms.
  • Urticaria and eczema both cause skin inflammation, albeit the patterns and processes of inflammation differ.
  • Allergens, irritants, stress, and temperature fluctuations can all cause both diseases to develop.
  • Urticaria and eczema, which cause discomfort, itching, and cosmetic issues, can have a substantial influence on a person's quality of life.
  • While exact treatments may differ, both disorders may benefit from similar tactics, such as avoiding triggers, applying moisturisers, and using drugs to manage symptoms.

While both urticaria (hives) and eczema create itchy skin rashes, there are significant variances. Urticaria is characterised by raised, red welts that emerge unexpectedly and then disappear within hours or days. Eczema, on the other hand, is a persistent skin ailment characterised by dry, scaly spots that leak or crust when touched. Understanding the differences between urticaria and eczema is critical for accurate diagnosis and treatment.
