Rashes can occur in allergic reactions due to the presence of mast cells within the skin. During a reaction these cells release histamine which produces symptoms. An allergy rash is generally red, elevated bumps. These bumps are also known as wheals, they may also be itchy.

The type of rash experienced, location of the rash and the severity is highly individual. Rash symptoms may appear in isolation or in conjunction with other allergy symptoms. Allergic rashes can occur in response to a food item, plants and medications.

Rashes can occur for reasons other than allergies and it is important to understand the cause of a rash. Other common rashes include those from infections such as bacteria, viruses or fungi. If you are unsure about the cause of a rash please see your GP or visit the pharmacy.

Also known as atopic dermatitis, eczema is a non-contagious chronic inflammatory skin condition. It is often hereditary and very common in children. Some infants will outgrow eczema, however, this is not the case for everyone. The condition results in very dry and sensitive skin, which can become inflamed with red itchy patches. The location of the patches can often be in the folds of joints however this may change over time. Irritation and itchiness from eczema can be severe and lead to scratching, breaking of the skin and in some cases, an infection.

Eczema can be exacerbated by exposure to allergens such as food items, pet hair, mould and dust. Certain products on the skin can also aggravate eczema such as shower gels, shampoos, lotions, perfumes and household cleaning products.
