Medicines whose labels list bradycardia

310 medicines have an FDA label that names bradycardia 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 bradycardia name metoprolol (3,427), bisoprolol (3,391) and amlodipine (2,727), 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.

Check it at the source: the FDA FAERS public dashboard; FDA labels on DailyMed.

Which medicines' labels list bradycardia?

Ordered by where the label names it, the boxed warning first, then by FAERS reports. The first 150 of the 310 are below; every other one is on its medicine record. A medicine whose own indications name it, because it treats it, is not counted.
