What it is
Eczema (dermatitis) causes dry, itchy, inflamed skin that may flare and settle. Contact dermatitis is a reaction to something that touched the skin.
Hives (urticaria) are raised itchy welts that come and go. Other conditions, such as psoriasis, can also cause scaly patches.
Common factors
- Personal or family history of eczema, asthma or hay fever
- Soaps, detergents, cosmetics, hair dye, metals and plants
- Foods or medicines (for some types of hives)
- Heat, sweat, stress and dry weather
When to see a dermatologist
- Itching disturbs sleep or daily life
- A rash is spreading, weeping or not improving
- You suspect a reaction to a product or medicine
- Swelling of lips, eyes or throat, or difficulty breathing. Get emergency care immediately
At your consultation
- 1The doctor asks about the timing of the rash, possible triggers, products, medicines and family history.
- 2Your skin is examined, and the likely type of rash and its triggers are explained.
- 3A treatment and skincare plan is agreed, including what to avoid.
Options that may be considered
Which, if any, is right for you is decided by the doctor after examining you.
- Prescription treatment matched to the type of rash
- Trigger identification and avoidance advice
- Skin barrier care and moisturising routine
Realistic expectations
- Eczema and some allergies are long-term conditions that are controlled rather than cured.
- Knowing your triggers usually means fewer flares.
Questions
Can you tell what I am allergic to?
Often the history and examination point to the likely trigger. If further tests would help, the doctor will discuss them with you.Verify: Confirm whether patch testing is offered at the clinic or by referral.
