Asthma patients must switch inhalers per FDA

Inhalers that contain environment-harming chemicals will no longer be sold after 2008 but the FDA but the government is urging people to switch to CFC-free inhalers now.

Chemicals called chlorofluorocarbons, or CFCs, once were widely used to propel the drug into the lungs. But CFC-containing consumer products are being phased out because CFCs damage the Earth's protective ozone layer. As of Dec. 31, asthma inhalers with CFCs can no longer be made or sold in the U.S. Inhalers instead will be powered by ozone-friendly HFAs, or hydrofluoroalkanes.

The ozone layer shields the planet from harmful ultraviolet radiation.
