Prednisone at a dose of about 1 mg/kg/day, quickly tapered. Clofazimine (note that the multibacillary regimen with clofazimine prevents type 2 lepra reactions) Thalidomide 400 mg/day for 5–10 days, tapered over 1–2 months.
Why thalidomide is used in lepra reaction?
Thalidomide is highly effective in the treatment of patients with chronic or recurrent ENL. It acts by inhibition of selective gene expression of tumour necrosis factor-α (TNF-α) involved in the pathogenesis of nerve damage in leprosy and other mechanisms contributing to its anti-inflammatory effect [13,14].
