Evaluating the Effect of Drug Provocation Tests on Anxiety and Hopelessness Levels.

Drug provocation tests (DPTs) diagnose drug hypersensitivity reactions (DHRs) and identify safe alternatives. DHRs contribute to patient anxiety. The aim of this study was to evaluate anxiety and hopelessness levels before and after DPT and to examine patients' avoidance characteristics of the tested drugs. Patients undergoing DPT were included. The State-Trait Anxiety Inventory (STAI) assessed anxiety, and the Beck Hopelessness Scale measured hopelessness. Demographic and clinical data, pre- and post-DPT scores, the status of using the medication provided after DPT, and the reason for not using it were analyzed. Seventy-nine patients (60 female, 75.9%) participated. Patients' Beck Hopelessness Scale, STAI-State, and STAI-Trait scores decreased significantly after the DPT compared to the initial scores. Among the patients who developed a reaction during the drug provocation test, the rate of those whose scale scores increased was significantly higher than the rate of those who did not develop a reaction. A total of 42 patients (53.2%) did not use the alternative safe drug. Of these, six (14.3%) reported that their reluctance stemmed from a fear of experiencing a reaction similar to their initial adverse event. Patients with concomitant allergic diseases were less likely to use alternative safe drugs. DPT reduces long-term anxiety and hopelessness. However, one in seven patients avoids the prescribed safe drug due to fear of recurrence. Effective communication, especially with patients who have allergic conditions or experience a reaction during DPT, and psychological support may improve adherence to the tested medication.
