Triamcinolone acetonide 0.1% is a mid‑ to high‑potency topical corticosteroid for corticosteroid‑responsive dermatoses such as eczema/atopic dermatitis, contact dermatitis, lichen simplex chronicus, and localized psoriasis, reducing inflammation, erythema, and itch via glucocorticoid receptor–mediated anti‑inflammatory effects. Apply a thin film to affected skin for short courses, avoiding face, groin, and axillae unless directed, then taper or step down potency once controlled; integrate moisturizers and trigger avoidance for maintenance. Reserve occlusion for clinician‑directed use and schedule follow‑up to assess response, rotating to lower‑potency agents on sensitive sites to preserve barrier and minimize steroid exposure.
