Lupus erythematosus exacerbated by griseofulvin.

Because griseofulvin is one of the safest systemic medications, its side effects are often forgotten. This paper serves as a reminder that griseofulvin can precipitate or exacerbate lupus erythematosus. Two patients are described: one had a photosensitivity reaction to griseofulvin which precipitated discoid LE skin lesions, without any previous evidence of LE. The other, who had known systemic LE, developed a systemic reaction, consisting of fever and malasise.
