A real-world adverse events study of rimegepant from the FAERS database.

Background: The primary objective of this research is to conduct an exhaustive evaluation of rimegepant with the Food and Drug Administration Adverse Event Reporting System (FAERS) repository.

Research design and methods: This study downloaded the reporting files related to rimegepant from the second quarter of 2020 to the first quarter of 2024. Disproportionality analysis was utilized to explore the relationship between rimegepant and adverse drug events (ADEs).

Results: This study analyzed 6659 ADE reports associated with rimegepant as the primary suspected (PS) drug. In the disproportionate analysis of system organ classes (SOCs), the significant signal for rimegepant was general disorders and administration site conditions.On the preferred terms level, 35 ADEs were identified following the exclusion. The top five ADEs with high signal strengths were medication overuse headache, nasal edema, tension headache, performance status decreased, and motion sickness. The most frequent ADEs were nausea, feeling abnormal, abdominal pain upper, somnolence, and hypersensitivity. In addition, we need to pay attention to the ADEs not mentioned in the instruction and clinically significant: vertigo, hyperacusis, somnolence, Raynaud's phenomenon, motion sickness, panic attack, and fear.

Conclusions: This study highlights previously unrecognized safety concerns associated with the use of rimegepant. These novel safety aspects suggest that while these treatments can be effective, additional risks may need further exploration.
