Actually up to two years is safe says my pulmonigist

Just call the pharmacist. I should be able to help you

my DR said to go ahead and use the one I was given in rehab. even thro it had expired.

if the date has expired then they recommend not using them at all return to the place of purchase in the same answer don't use any medications once passed the use by date as it can change the construction of the medications and this defaults the use for the medication and can lead to illness yep I know we are already ill but who wants to get sicker have a great day

Years ago we did not have sell by dates on anything, and we survived. There is too much fuss today, over not using it passed its date time. I open it, smell it, taste it if you can. Inhalers I would use. Happy breathing. God bless.
