Irritant contact dermatitis

Irritant contact dermatitis means a skin reaction that is caused by directly touching an irritating substance, and not by an infectious agent such as a bacteria or virus.

Common causes are soap, bleach, cleaning agents, chemicals, and even water. Almost any substance can cause it with prolonged exposure. Contact dermatitis is not contagious.

Anyone who works with an irritating substance can contract the condition. Mechanics, beauticians, housekeepers, restaurant workers, and health care providers are all susceptible.

Symptoms include skin that feels swollen, stiff, and dry, and becomes cracked and blistered with painful open sores.

A medical provider can give the best advice on how to heal the skin and avoid further irritation. Self-treatment can make the problem worse if the wrong creams or ointments are used.

Diagnosis is made through patient history, to find out what substances the patient comes into contact with, and through physical examination of the damaged skin.

Treatment involves avoiding the irritating substance if possible. Otherwise, the person can use petroleum jelly on the hands underneath cotton and then rubber gloves.

Rarity: Common

Top Symptoms: rash with well-defined border, itchy rash, red or pink, rough patch of skin, painful rash, red rash

Symptoms that always occur with irritant contact dermatitis: rash with well-defined border

Symptoms that never occur with irritant contact dermatitis: fever, black-colored skin changes, brown-colored skin changes, blue-colored skin changes

Urgency: Self-treatment
