THURSDAY, Sept. 22 (HealthDay News) -- Over-the-counter asthma
inhalers containing chloroflouorocarbons (CFCs), which can damage
the ozone layer, will not be made or sold after Dec. 31, the U.S.
Food and Drug Administration announced Thursday.
The sole product affected is Primatene Mist, marketed by
Armstrong Pharmaceutical Inc., because it is the only inhaler
approved by the FDA to be sold without a prescription for the
relief of occasional symptoms of mild asthma.
"With this phase-out, all of the other inhalers that could substitute for the CFC over-the-counter inhaler to relieve symptoms of mild asthma require a prescription," Dr. Andrea Leonard-Segal, director of the FDA's Division of Nonprescription Clinical Evaluation, said during a morning news conference.
Primatene Mist uses CFCs to propel epinephrine from the inhaler
so it can be taken into the lungs.
"Consumers who use Primatene Mist need to take action now to see a health-care provider to get a prescription for a replacement product," Leonard-Segal said. "Primatene Mist may be even harder to find on store shelves even before Dec. 31, 2011."
People who have the product after Dec. 31 can continue to take
it as long as it hasn't expired, Leonard-Segal said.
The product is being removed from the market to comply with the
Montreal Protocol on Substances that Deplete the Ozone Layer. This
international agreement, signed by the United States and other
nations, calls for phasing out chemicals that deplete the ozone
layer, including CFCs.
Many manufacturers have replaced CFCs with an environmentally
friendly propellant called hydrofluoroalkane (HFA). However, there
are no HFA versions of over-the-counter epinephrine inhalers
currently available, the FDA said.
While the other types of medications delivered through HFA
inhalers are effective, there are some significant differences
between HFA and CFC inhalers that people need to be aware of,
