High Potency Topical Corticosteroid Options for Severe Skin Conditions
For severe skin conditions requiring high potency topical corticosteroids, clobetasol propionate 0.05% is the most effective option, available in cream, ointment, and gel formulations, and should be applied twice daily for up to 2 weeks with a maximum of 50g per week. 1

Application Guidelines for Severe Skin Conditions
For Localized Severe Disease
- Apply very potent topical steroids to lesional skin only 4
- Suitable for smaller areas of involvement
- Reduces risk of systemic absorption compared to whole-body application
For Extensive Severe Disease
- For generalized disease with large areas of involvement, apply super-potent topical corticosteroids to the whole body except the face 5
- In bullous pemphigoid, clobetasol propionate 0.05% cream (20g) applied all over twice daily (total 40g daily) showed significant benefit for disease control, adverse events, and mortality compared to oral prednisone 4
Dosing Considerations
Fingertip Unit Method
- One fingertip unit (FTU) = amount from fingertip to first finger crease
- One FTU covers approximately 2% body surface area in adults 6
- Helps ensure correct amount is applied
Duration Limitations
- Super-high potency corticosteroids: Maximum 2-3 weeks 1, 6
- High or medium potency: Maximum 12 weeks 6
- Treatment should be discontinued when control is achieved 1
- If no improvement after 2 weeks, reassessment of diagnosis may be necessary 1
Formulation Selection
Ointments
- Most potent vehicle
- Best for thick, chronic plaques and very dry skin
- Provides better occlusion and hydration
- Disadvantage: greasy feel
Creams
- Good for most body areas
- Better cosmetic acceptability than ointments
- Useful for acute or subacute dermatoses
- Clobetasol propionate emollient cream (with moisturizers) may improve moisture content in treated skin 7
Gels, Foams, Solutions
- Preferred for scalp and hairy areas
- Less greasy feel
- Good for acute weeping dermatoses
Special Considerations and Precautions
High-Risk Areas
- Face, genitals, intertriginous areas: Avoid super-high potency steroids due to increased risk of skin atrophy 5, 6
- Use lower potency steroids or topical calcineurin inhibitors in these areas 5
Monitoring for Adverse Effects
- Local effects: skin atrophy, striae, telangiectasia, folliculitis, purpura 5, 8
- Systemic effects: HPA axis suppression possible with extensive use 1, 8
- Risk increases with:
- Prolonged use
- Large area of application
- Higher potency
- Occlusion
- Application to thin-skinned areas 6
Adjunctive Measures
- Liberal moisturization is essential as adjunctive treatment 5
- Use dispersible creams as soap substitutes 5
- Avoid irritants such as soaps and detergents 5
When to Consider Alternatives
- If inadequate response after 2-4 weeks of appropriate topical steroid therapy 5
- Consider systemic therapy for widespread severe disease 4
- For bullous pemphigoid not responding to topical therapy, consider systemic corticosteroids (0.5-1.0 mg/kg daily) 4
Remember that while super-high potency topical corticosteroids are extremely effective for severe skin conditions, their use must be carefully monitored due to the potential for significant local and systemic adverse effects with prolonged or excessive use.
