The only over-the-counter asthma inhaler sold in the United States will no longer be available next year as part of an international agreement to stop the use of substances that damage the environment.
Primatene Mist (epinephrine) is approved by the Food and Drug Administration (FDA) for the temporary relief of occasional symptoms of mild asthma. FDA urges those who use Primatene Mist to see a health care professional soon to switch to another asthma medicine.
Primatene Mist inhalers are being discontinued because they use chlorofluorocarbons (CFCs) as a propellant (spray) to move the medicine out of the inhaler so patients can breathe the medicine into their lungs.
From the Big Government article:
CFCs from inhalers were a trivial contributor and should have been permanently exempted from these regimes until something just as good and just as affordable came along. They weren’t, and it hasn’t.
