Dermatologic side effects have included severe skin reactions (including Stevens-Johnson syndrome and toxic epidermal necrolysis) and erythema multiforme. Fixed-drug eruptions, photosensitivity, exacerbation of systemic lupus erythematosus (SLE), and SLE-like syndromes have been reported. A patient with Hailey-Hailey disease (chronic benign familial pemphigus) experienced a widespread bullous eruption due to griseofulvin therapy. Lesions have commonly begun on sun-exposed areas.
Fixed-drug eruptions have been verified by rechallenge.
At least one reported case of toxic epidermal necrolysis resulted in death.
At least one fatal case of SLE exacerbation occurred after ingestion of approximately 1 gram of griseofulvin.
Nervous system side effects have included headache, insomnia, dizziness, and mental confusion. Neuropathy and development of paresthesia of the hands and feet have been reported with long-term use.[Ref]
Neuropathy and paresthesia have been reported in a few cases of long-term griseofulvin therapy.
