Table 2: Relative potency of topical corticosteroids*

TC are divided into four groups according to their potency in keeping with the British National Formulary (BNF), while American system classifies them into seven classes, [23] with class I being the super potent or ultra potent and class VII represent the least potent [Table 2]. Although a thorough knowledge of drugs in each class may be ideal, practically a physician should become familiar with one or two agents in each category of potency to safely and effectively treat steroid-responsive skin conditions.

As a general rule, low potency steroids are the safest agents for long-term use, on large surface areas, on the face, or on areas with thinner skin and for children. More potent TC are helpful for severe disease and for thicker skin of palms and soles. High and ultra-high potency steroids should not be used on the face, groin, axillae, and under occlusion; except in rare situations and for short duration.
