Drug allergy is a very common condition faced by both primary care physicians  and hospital physicians  worldwide. Drug allergy is further complicated by the underlying disease, which frequently prevents the use of the usual first-line treatments.
Furthermore, allergists know that patients who have experienced an allergic drug reaction, especially those who have had a severe reaction, are increasingly fearful of new allergic reactions and therefore tend to avoid taking any type of medication. In a previous study , we validated the Spanish version of the Drug Hypersensitivity Quality of Life (DHRQoL) questionnaire, which was developed in Italy by Baiardini et al . In the present paper, we report the results of our psychometric validation of the questionnaire.
