What do FAERS reports show for cenobamate?

The FDA Adverse Event Reporting System holds 8,296 reports that list cenobamate among the medicines taken, through July 30, 2026, each a report of something that happened, not proof the medicine caused it; 197 are coded as a death and 1,666 as a hospital stay. Counts follow how widely a medicine is used and watched, and they are not a measure of how risky it is. Reports rose sharply in 2025 (2,052, against a median of 83 a year): FAERS counts follow reporting, which news, litigation and label changes can drive, not how often a reaction happens.
