Occupational allergic contact dermatitis from tetrazepam in nurses.
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.


CONCLUSIONS
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.
