Albuterol is a quick-relief medication that's used to open up the airways so that it's easier to breathe. The medication is used by people with certain airway diseases, such as asthma and chronic obstructive pulmonary disease (COPD), a group of lung diseases that includes chronic bronchitis and emphysema.
One method of delivering albuterol is the metered dose inhaler, a hand-held device that delivers a specific amount of medication directly into the lungs. Traditionally, inhalers have contained chlorofluorocarbons (CFCs), a type of propellant that helps the albuterol reach the lungs. But inhalers with CFCs are being phased out because they are harmful to the environment.
Whether it’s because of the flu or seasonal allergies, diabetes or epilepsy, pregnant women must often take prescription medication—usually while worrying about the potential impact on their developing babies.
With studies showing the average woman takes from three to five medications while pregnant, the Food and Drug Administration (FDA) encourages drug makers and moms-to-be to participate in pregnancy registry studies that track the risks from drugs taken during pregnancy or breastfeeding.
Here are facts you should know about switching from your CFC-propelled albuterol inhaler to inhalers that contain propellants called hydrofluoroalkanes (HFAs).
CFCs deplete the ozone layer.
CFCs deplete ozone high up in the stratosphere--the part of the earth's atmosphere that protects us from the sun's harmful ultraviolet radiation. In the stratosphere, the ozone layer serves as a shield that absorbs ultraviolet radiation and keeps it from reaching the earth's surface. CFCs are among the substances that damage the ozone layer. This leads to higher levels of ultraviolet B radiation, which has negative effects, including increases in skin cancers and cataracts. Under an international agreement, the United States, along with almost all countries of the world, agreed to phase out CFCs and other ozone-depleting substances.
CFC-propelled albuterol inhalers will no longer be available after Dec. 31, 2008.
In accordance with an FDA Final Rule and under the authority of the Clean Air Act of the U.S. Environmental Protection Agency, no CFC-propelled albuterol inhalers can be produced, marketed, or sold in the United States after Dec. 31, 2008. Manufacturers have been increasing production of HFA-propelled albuterol inhalers so that sufficient supplies exist to replace the CFC-containing inhalers. If you haven't done so already, you should talk with your health care professional about switching to an HFA-propelled albuterol inhaler.
Albuterol inhalers containing HFAs deliver the same medicine, but there are some differences.
The HFA-propelled albuterol inhalers are still convenient and have been shown to be safe and effective in studies with patients. But you may find that the spray from an HFA inhaler tastes and feels different than the spray from the CFC-propelled albuterol inhalers. The spray from an HFA inhaler may feel less forceful, but this does not mean that the medication is not working.
