Reported Outcomes
Outcomes recorded in FAERS reports that included Rapidol. A single report may involve multiple reactions, each with a different outcome. These categories are defined by FDA reporting guidelines, not by PillSignal.
View outcome data as a table
| Outcome | Reports |
|---|---|
| Other Serious | 161,109 |
| Hospitalization | 132,621 |
| Death | 55,255 |
| Non-Serious | 41,317 |

| Disability | 13,842 |
Serious outcomes are far more likely to be reported than mild ones, so this overstates how often outcomes are serious. A recorded death does not mean the drug caused it.
Report Volume Over Time
Number of FAERS reports received per quarter for Rapidol. Changes in volume may reflect shifts in prescribing rates, media attention, or reporting behavior, not changes in the medication's safety profile.
