Asthma patients who rely on over-the-counter inhalers will need to switch to prescription-only alternatives as part of the federal government's latest attempt to protect the Earth's atmosphere.
The Food and Drug Administration said Thursday patients who use the epinephrine inhalers to treat mild asthma will need to switch by Dec. 31 to other types that do not contain chlorofluorocarbons, an aerosol substance once found in a variety of spray products.
The action is part of an agreement signed by the U.S. and other nations to stop using substances that deplete the ozone layer, a region in the atmosphere that helps block harmful ultraviolet rays from the Sun.
But the switch to a greener inhaler will cost consumers more. Epinephrine inhalers are available via online retailers for around $20, whereas the alternatives, which contain the drug albuterol, range from $30 to $60.
