Recommendations for Patients Who Used Primatene Mist

Author: Jeannette Y. Wick, RPh, MBA, FASCP

As of the end of 2011, the only OTC asthma inhaler was removed from shelves due to its damaging effect on the environment.



At the end of 2011 and after 50 years of availability, the only OTC asthma inhaler, Primatene Mist (epinephrine), was removed from the shelves. Pharmacists may field questions from the approximately 3 million patients who relied on Primatene Mist about what to do next. Most studies indicate that patients used Primatene Mist out of convenience rather than financial concern.

Primatene Mist was discontinued not because it was ineffective, but because its operation relied on chlorofluorocarbon (CFC) propellants, which are harmful to the environment because they deplete the ozone layer in the earth’s upper atmosphere. The United States promised to discontinue use of CFCs after signing the Montreal Protocol on Substances that Deplete the Ozone Layer. Most inhalers that once depended on CFCs now use hydrofluoroalkane instead.

"Primatene Mist does not treat asthma—it treats symptoms that can come from asthma," Kyle Hogarth, MD, an assistant professor of medicine and the medical director of the pulmonary rehabilitation program at the University of Chicago Medical Center, told the Los Angeles Times.

Pharmacists can provide the following guidance to patients: Combivent Inhalation Aerosol (albuterol and ipratropium in combination) and Maxair Autohaler (pirbuterol) are the last 2 inhalers containing CFCs. They may be sold until December 31, 2013.
