Reported Outcomes
Outcomes recorded in FAERS reports that included Cyclosporine Modified. 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 | 37,149 |

| Death | 10,556 |
| Non-Serious | 5,072 |

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.
