We report on 3 cases of contact dermatitis following topical application of etofenamat. Each patient developed positive reactions in patch tests with etofenamat in concentrations of both 10% and 1%. After testing, one patient showed secondary inflammatory reactions at the original site of application. Considering the frequent administration of etofenamat, contact sensitization seems to be relatively rare.
