The latter is not related to the dosage but to cell-mediated hypersensitivity (dapsone hypersensitivity syndrome, DHS), ranging from mild cutaneous manifestations to severe life-threatening complications, such as exfoliated dermatitis, liver function failure, agranulocytosis, toxic epidermal necrolysis, nephritis and renal failure, Stevens-Johnson syndrome, etc.
Once this response, called cell-mediated hypersensitivity, is established, a person's T cells 'usually will respond to the tuberculin skin test (PPD test) and produce a characteristic red welt.
