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.
CFCs harm the environment by decreasing the earth's ozone layer. This layer of the atmosphere protects us from some of the sun’s harmful ultraviolet radiation, which can increase the risk of skin cancers and cataracts. The United States and most other countries have signed an international agreement to phase out CFCs and other ozone-depleting substances.
“There are many other safe and effective medications to treat the symptoms of asthma,” says Badrul Chowdhury, M.D., Ph.D., director of FDA’s Division of Pulmonary, Allergy, and Rheumatology Products. But you need to find out if you really have asthma—not just pick another over-the-counter medicine, adds Chowdhury. “If you have breathing problems but have not been diagnosed by a health care professional, it’s important to see one. Not all breathing problems are asthma, so you need to get an accurate diagnosis and the proper medicine.”
FDA first began public discussion about the use of CFCs for Primatene Mist and generic epinephrine inhalers in January 2006. FDA finalized the phase-out date for using CFCs in these inhalers and notified the public in November 2008.
Many manufacturers have changed their inhalers to replace CFCs with an environmentally friendly propellant called hydrofluoroalkane (HFA). There is currently no HFA version of the Primatene Mist inhaler.
