Hi Peggy,

Thank you for your question.  The new HFA inhalers look just like the inhalers you have used.  The medicine in the new HFA (hydrofluoroalkane) inhalers is the same medicine in the inhalers being replaced (Chlorofluourocarbon - CFC).  Some differences between the HFA and the CFC inhalers that you may not see: the HFA inhaler might be slightly different in smell and taste, the mist from the canister may be less forceful and warmer, and the inhaler may need to be cleaned and cared for differently.  These new HFA inhalers also have to be primed before using them for the first time, or if they haven't been used in about 2 weeks.  Priming means releasing 2 to 3 pumps into the air.  Keep in mind that you are only releasing the propellant that is used to in the inhaler into the air, not the medicine.  Also, these new HFA inhalers have a shorter shelf life and come with an expiration date of 3 to 4 months, depending on the inhaler.

It really is important fore everyone to understand that the medicine is not changing in the inhalers.  And with all inhalers, it really is best to use a holding chamber/spacer to administer the medicine.  If you feel the new HFA inhalers are not working or you are experiencing some trouble, please talk to your doctor.  Have a safe transition!
