What do FAERS reports show for ublituximab?

The FDA Adverse Event Reporting System holds 3,781 reports that list ublituximab among the medicines taken, through July 30, 2026, each a report of something that happened, not proof the medicine caused it; 62 are coded as a death and 449 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 (1,782, against a median of 10 a year): FAERS counts follow reporting, which news, litigation and label changes can drive, not how often a reaction happens.
