What do FAERS reports show for lotilaner?

The FDA Adverse Event Reporting System holds 3,098 reports that list lotilaner among the medicines taken, through July 30, 2026, each a report of something that happened, not proof the medicine caused it; 27 are coded as a death and 57 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 (1,253, against a median of 1 a year): FAERS counts follow reporting, which news, litigation and label changes can drive, not how often a reaction happens.
