Side effects across medicines
Medicines whose labels list wheezing
261 medicines have an FDA label that names wheezing 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 wheezing name montelukast (7,647), tiotropium (6,890) and budesonide and formoterol (5,738), 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 wheezing?
Ordered by where the label names it, the boxed warning first, then by FAERS reports. The first 150 of the 261 are below; every other one is on its medicine record. A medicine whose own indications name it, because it treats it, is not counted.
