Topical Steroids for Hidradenitis Suppurativa
Intralesional triamcinolone (10 mg/mL, 0.2-2.0 mL per lesion) is the recommended topical steroid approach for acute, inflamed HS lesions and localized flare-ups, providing rapid pain relief within 24 hours and reducing erythema, edema, and lesion size. 1
Evidence Basis and Strength
The North American HS guidelines consistently recommend intralesional corticosteroids based on Level III evidence (expert consensus and case series data). A prospective case series demonstrated significant improvements in physician-assessed parameters including erythema, edema, suppuration, and lesion size, with notable pain reduction on VAS scores occurring as early as 1 day post-injection 1. While the evidence quality is limited, the rapid symptomatic relief and short-term disease control make this a valuable intervention for acute flares across all Hurley stages 1.
Important Caveats
- Topical corticosteroid creams or ointments are NOT recommended - the guidelines specifically address intralesional injection, not surface application
- The evidence is weak (Level III), based primarily on expert opinion and small case series rather than randomized controlled trials
- This is a short-term control measure for acute flares, not a maintenance therapy
- Intralesional steroids should be used as part of a multimodal approach, not as monotherapy
Special Population Considerations
In pregnant patients with HS, intralesional steroids can be used for acute, localized flares based on expert opinion aligned with the general HS population, though no specific safety data exist for this population 2.
Practical Application
For acute inflamed nodules or abscesses:
- Inject triamcinolone 10 mg/mL directly into the inflamed lesion
- Use 0.2-2.0 mL per lesion depending on size
- Expect pain relief within 24 hours
- Combine with other modalities (antiseptic washes, systemic antibiotics) for optimal outcomes
This approach is appropriate for:
- All Hurley stages during acute flares
- Bridging therapy while initiating systemic treatments
- Adjunctive treatment alongside long-term management strategies
