This is source I found from another site, main source you can find in last paragraph

Inhalers containing chlorofluorocarbons, or CFCs, will be phased out by the end of the year to comply with international treaties intended to protect the the ozone layer.

The U.S. Food and Drug Administration made the announcement, which is part of an ongoing phase-out of the inhaler products. Only two remain on the market: Combivent Inhalation Aerosol and Maxair Autohaler. The FDA advises patients using these products to see their doctors for alternative treatment.

Inhalers are critical to the health of the 25 million Americans who suffer from asthma and the 15 million Americans diagnosed with chronic obstructive pulmonary disease. Asthma constricts the airways and can cause coughing, difficulty in breathing and tightness or pain in the chest.

Chronic obstructive pulmonary disease is a serious lung disease that grows worse over time. Symptoms can include chest tightness, chronic cough and excessive phlegm.
