It is important to use the correct amount of topical steroid for your eczema, as instructed by your healthcare professional. Topical steroids should be applied with clean hands so that the skin just glistens. It can sometimes be difficult to judge how much steroid to use and there are guidelines on the amount required to cover body areas that are affected by eczema. These are based on the Finger Tip Unit (FTU), and explained in detail in our fact sheet which you can download as a pdf from the related documents to the right of this page.
Topical corticosteroids are available in a wide range of different strengths, from Class 1 (very strong) to Class 7 (very weak). Stronger corticosteroids are generally more effective in reducing moderate to severe symptoms, such as thick, chronic plaques, but are also more likely to cause side effects 2 . Lower strength corticosteroids are generally better for milder symptoms and for very sensitive areas of the body (such as the face or groin areas) and stronger strengths are better for areas with thicker skin (such as the knees and elbows).
There is no agreed treatment for topical corticosteroid withdrawal, apart from ceasing the topical corticosteroid. However whether this should be tapered or abrupt has not been determined. Japanese reports suggest there is minimal difference in the outcome, so recommend immediate cessation. A tapering course of oral steroids is helpful, as the addiction appears to relate only to the use of topical corticosteroids. Oral tetracyclines and low-dose isotretinoin have been used in steroid rosacea and perioral /periorificial dermatitis .
