Really tired of instruction-many of us are capable of reading and following instruction!!!! So 3 of the RESCUE inhalers contain ethanol-if you have a corn allergy???? Ok now Ventolin doesn't use ethanol-well what does microcrystallized ingredient mean??? Is that also corn based? All of the rescue inhalers worsened my asthma-causing severe broncospasm, nausea and rash like burns-even the so called other choice Ventolin. So the FDA thinks they have given us choices-well, not in my opinion-clearly an inferior product at the cost of the health of many Asthmatics!!! Is the FDA listening? No, they aren't!! Google, Save CFC inhalers-join us in the fight to breathe.
