Patient Information Leaflets (PILs)

These Patient Information Leaflets (PILs) are specially written by the British Association of Dermatologists (BAD).

The BAD has been awarded The Information Standard certification for the process it employs to develop information products aimed at the general public, which include PILs, Sun Awareness Campaign materials, and other information products.

The BAD shall hold responsibility for the accuracy of the information published, and neither the scheme operator nor the scheme owner shall have any responsibility for costs, losses, or direct or indirect damages or costs arising from inaccuracy of information or omissions in information published on the website on behalf of the BAD.

Please note:

  1. There are thousands of different skin complaints, therefore, the focus of the British Association of Dermatologists' PILs production is on the most common, rarest or debilitating skin conditions.
  2. The offer to provide details of source materials used to inform the British Association of Dermatologists' PILs is for instances where the advice provided in the PILs does not reflect local practice and therefore evidence supporting said advice needs to be produced. It is not an offer to conduct literature searches or supply bibilographic materials for your own research.

Urticaria and angioedema

Urticaria is a common illness affecting up to 20% of people (one in 5 people) at some point in their lives. Urticaria presents with highly itchy raised skin reactions known as weals (also known as hives) that may be round or ring-shaped, and may join together. They come and go within hours. Weals can also appear as raised lines after scratching. They can appear anywhere on the skin. Individual weals typically disappear of their own accord within 24 hours without a trace but the condition lasts longer.  Angio-oedema, swelling deep to the skin, often occurs in urticaria. Angio-oedema usually affects soft areas of skin, such as the eyelids, lips or inside the mouth but may occur anywhere. These swellings often take longer to clear and tend to be painful rather than itchy. Urticaria may present with weals alone, angio-oedema or both together.

If angio-oedema occurs without weals it may be an inherited illness called hereditary angio-oedema. This is a different problem to urticaria. It can be diagnosed with blood tests and needs different treatment.
