BACKGROUND: Tetrazepam is a muscle relaxant belonging to the benzodiazepine group. Drug eruptions following ingestion of tetrazepam tablets are well known. OBJECTIVE: To draw the attention to occupational airborne dermatitis and/or hand dermatitis in nurses resulting from crushing of tablets for elderly or disabled people. METHODS: Since 2003, 16 nurses with facial (eyelid) and/or hand dermatitis, suspected to be of occupational origin, were patch tested with the medication they handled during work. RESULTS: Ten nurses presented with a positive patch test reaction to tablets containing tetrazepam, 14 controls remaining negative. Some of them also reacted to other drugs. CONCLUSION: Occupational airborne and/or hand contact dermatitis from tetrazepam might be much more common than suspected by dermatologists, particularly in view of the short period in which all cases have been observed.
