title: Subacute cutaneous lupus erythematosus induced or exacerbated by terbinafine: a report of 5 cases.
abstract: BACKGROUND
  Subacute cutaneous lupus erythematosus is a nonscarring, non-atrophy-producing photosensitive cutaneous disorder. Half of the patients have 4 or more of the criteria for classification as systemic lupus erythematosus. In some patients, drugs induce or exacerbate the cutaneous disease.
  
  
  METHODS
  We describe 5 patients who had either an exacerbation or a new onset of subacute cutaneous lupus erythematosus while taking terbinafine for presumed onychomycosis.
  
  
  CONCLUSIONS
  In general, terbinafine is a safe drug, but perhaps patients with known lupus erythematosus or photosensitivity are predisposed to drug-induced or drug-exacerbated disease.
