first metered-dose inhaler that doesn't contain chlorofluorocarbons (CFCs)
Starting this month you can prescribe the first metered-dose inhaler that doesn't contain chlorofluorocarbons (CFCs)...Proventil HFA.
Eventually all CFCs will be phased out...they deplete the ozone.
Proventil HFA contains hydrofluoroalkane-134a (hence the HFA). HFA gives a softer spray...no cold Freon-like effect on the back of the throat.
