Primatene Mist is a trade name for an epinephrine metered-dose inhaler sold over-the-counter in the United States for the relief of bronchial asthma. It is manufactured by Armstrong Pharmaceuticals, a company based in Canton, Massachusetts and a subsidiary of Amphastar Pharmaceuticals, located in Rancho Cucamonga, California.
Because Primatene Mist contains chlorofluorocarbon, it can no longer be prescribed or sold. This ban was unsuccessfully challenged in the United States Senate in November 2011.

The bronchodilator brand Primatene Mist was introduced in 1963 by Armstrong Pharmaceuticals. In October 2003, Armstrong was bought by Amphastar Pharmaceuticals. In 2008, the Food and Drug Administration (FDA) announced that Primatene Mist inhalers, which contain chlorofluorocarbons (CFCs), failed to comply with the environmental regulations of the Montreal Protocol and therefore could not be manufactured or sold after December 31, 2011. Armstrong Pharmaceuticals is currently developing an HFA version of Primatene Mist to replace the CFC inhalers. 
Legislation authored by Senator Jim DeMint to overturn the ban was defeated by the Senate in November 2011.
