Abstract

Despite the need for immediate treatment during acute allergic reactions (AARs), many patients do not consistently carry medication. A new mouth-dissolving dexamethasone film offers a portable, easily administered alternative to corticosteroid tablets. This non-randomized, open-label, low-interventional real-world trial assessed satisfaction (accessibility and safety/security) with the mouth film versus betamethasone tablets in adults prescribed tablets for moderate to severe AARs at a Swedish primary care center. Over six months, participants had access to both treatments and reported monthly via an electronic diary; qualitative responses were converted to Likert scales where applicable. Of 50 enrolled, 44 provided diary data (mean age 50 years, 74% female, 58% had an epinephrine autoinjector). In total, 189 responses were collected: 98% stated that the participant was satisfied or very satisfied with mouth film accessibility versus 58% for tablets (mean Likert scores 3.5–3.7 vs. 2.5–2.8; p < 0.001). A higher feeling of safety with the mouth film versus tablets was reported in 78% of responses and improved medication carriage compliance in 77%. At six months, 69% preferred the film. Of 18 AARs in total reported by 13 participants, the mouth film was chosen for treatment of 16 (11 participants); in 94%, the mouth film was found immediately accessible, and in 94%, the efficacy was rated as good or very good. In conclusion, the mouth film improved perceived accessibility, safety/security, and medication-carriage compliance compared with tablets for the treatment of AARs.
