Guidelines for the treatment of atopic eczema recommend that application amount of topical anti-inflammatory therapy should follow the FTU rule. In the USA it has been recommended that the FTU should be used as part of the treatment plan and communication with patients and caregivers of

In the original study in the UK, one FTU weighed 0.49 g in men and 0.43 g in women. The area covered by one FTU was 312 cm in men and 257 cm in women. Very similar results were found in a Mexico study. The weight of an FTU has been recalculated in Japan, relating to the use of

Working Groups in the UK and in Poland have recommended that guidance for use of topical corticosteroids in patient information leaflets should include clear FTU instructions, preferably with images of a FTU and a chart to show the number of units required for specific areas of the

One handprint is 0.8% (i.e. approximately 1%) of the total body surface area, and one FTU covers approximately two handprints. As two FTUs are approximately equivalent to 1g of topical application, the "Rule of Hand" states that "4 hand areas = 2 FTU = 1 g".

The FTU is particularly useful when counseling patients with regards to the amount of topical steroid cream they should be applying in order to minimize the side-effects which are associated with their use. The FTU can also be used in children.

The use of the FTU has been advocated to reduce the variation in usage of topical steroids and to encourage adherence to therapy. The FTU can also be used to guide the use of topical sunscreens.
