| Potency Level | Examples | Clinical Use |
|---|---|---|
| Low (Class VI-VII) | Hydrocortisone 1-2.5% | Face, intertriginous areas, children |
| Medium (Class III-V) | Triamcinolone, Betamethasone | Body surfaces, moderate inflammation |
| High (Class I-II) | Clobetasol, Halobetasol | Thick skin areas, severe conditions |
A 6-year-old child presents with atopic dermatitis on the face. The appropriate choice would be low-potency hydrocortisone 1% rather than a high-potency steroid due to increased absorption risk in children and facial skin.
Face = Low potency only
Absorption increases with occlusion
Children need lower potency
Elderly have thinner skin
Intertriginous areas = higher absorption
Thin skin = more absorption
Never apply topical glucocorticoids to infected skin without concurrent antimicrobial therapy as steroids can worsen infections by suppressing local immune response.
| Concept | Topical Glucocorticoids | Topical Antibiotics |
|---|---|---|
| Primary Action | Anti-inflammatory | Antimicrobial |
| Use with Infection | Contraindicated alone | First-line treatment |
| Duration Limits | Yes (2-4 weeks max) | Usually 7-10 days |
Remember: When choosing topical glucocorticoids, always consider patient age, application site, and condition severity. Start with lowest effective potency and increase only if needed.
□ Can you identify appropriate potency levels for different body areas?
□ Do you know the maximum duration for high-potency topical steroids?
□ Can you recognize signs of systemic absorption?
⚠️ Don't confuse potency with concentration percentage
⚠️ Remember that facial skin requires low-potency agents
⚠️ Never recommend topical steroids for infected lesions without antimicrobials
