Side effects across medicines
Medicines whose labels list rash
1,495 medicines have an FDA label that names rash in its boxed warning, warnings, adverse reactions, trial table, patient leaflet or Drug Facts “stop use” warning (of the labels PlainMeds reads: each medicine's quoted label and up to eight more, by route and wording). Among them, the most FAERS reports of rash name dupilumab (38,629), adalimumab (25,746) and methotrexate (22,362), through July 30, 2026. A label lists what its studies and reports found, and a report does not show that a medicine caused the event.

Which medicines' labels list rash?
Ordered by where the label names it, the boxed warning first, then by FAERS reports. The first 151 of the 1,495 are below; every other one is on its medicine record. A medicine whose own indications name it, because it treats it, is not counted.
