Mebendazole is a benzimidazole derivative widely used as an anthelminthic and reactions to it are few. To the best of our knowledge this is the first report of a case of fixed drug eruption (FDE) due to mebendazole.

  Case Report Top

A forty - six - year old lady came to the hospital for complaints of well circumscribed pigmented macules, 2-3 cms in size over the lips and dorsa of hands since eight months. There was a history of erythema and edema of these lesions and development of fresh macules off and on. On questioning, she ad­mitted frequent self medication with mebendazole tablets for pruritus ani during the past two years. She was not on any other drugs. Three hours after the administration of a single tablet of mebendazole, the pigmented macules became erythematous, edematous and blistered.

  Comments Top

Systemic toxicity due to mebendazole is rare in clinical practice. Perhaps this is due to its poor absorption. However, transient symp­toms of abdominal pain and diarrhoea have occurred when it is given to patients with massive worm infestation.[1]

The reported efficacy of mebendazole in the treatment of scabies[2] and cutaneous larva migrans,[3] suggest that the drug is indeed absorbed in sufficient amounts to pro­duce parasiticidal concentration in the skin therefore it is capable of inducing drug reac­tions.

Several drugs, certain dyes and food ad­ditives are known to produce FDE. Though the commonest presentation is a pigmented macule, sharply defined erythematous, ec­zematous, vesicular, papular, acneiform, purpuric, herpetiform to erythema multiforme like lesions have also been reported.[4]
