So, if you have one of these above inhalers, you'll all set. You don't need to switch. Your lungs - and the earth's atmosphere - will thank you!

Will I See a Price Difference?
There may be a significant price difference between the CFC inhalers and the new HFA inhalers, particularly if you currently use a generic CFC inhaler. The HFA inhalers cost from $30 to $60, compared with $5 to $25 for a generic CFC inhaler. The price difference is most likely to have an impact on patients without health insurance, and it is hoped that as more people move to the CFC-free delivery method, the price will come down.

If you have questions about the transition to HFA inhalers or to learn about assistance programs that may help you pay for your prescriptions, including a coupon offer, you can call the American Lung Association Lung HelpLine at 1-800-LUNG-USA, and press "2" to speak to a nurse or respiratory therapist.

The clock is ticking, and even if your lungs are well maintained, you don't want to be left out in the cold without your quick relief inhaler. Find out about the switch today!

Remember that this is not medical advice, but general information. As always, talk with your doctor. He or she knows you best.
