What are the common triggers for contact dermatitis that I should advise my patients to avoid?

Common triggers for contact dermatitis that patients should avoid include:

• Soaps and detergents, especially those containing irritants or allergens.
• Certain chemicals and occupational substances that may cause irritant or allergic reactions.
• Products containing known allergens such as preservatives, fragrances, and rubber or latex components.
• Exposure to water and chemicals under jewellery, which can accumulate and irritate the skin.
• Use of aqueous cream as a leave-on emollient, due to its potential to cause skin reactions.
• Smoking or exposure to naked flames when emollients are in contact with dressings, clothing, or bedding, due to fire risk.

Patients should be advised to avoid identified causative agents as avoidance is the most important element in treatment and prevention of recurrent episodes of contact dermatitis. If complete avoidance is not possible, measures such as rinsing the skin promptly after contact, substituting products with non-allergenic alternatives, and using protective gloves (cotton-lined rubber or plastic) are recommended to minimise exposure and irritation. Gloves should be removed frequently to prevent sweating, which can worsen dermatitis ¹.
