I agree with Jean 100% talk to your doctor a lot of times they can provide free samples for you to try. Also check with your insurance company they pay on different scales for these meds. I started out with Spairiva two years ago as a tier one drug 10.00 copay, last year it went to a tier two (35.00 copay) this year it is a tier three (75.00) so my doctor changed me to Tuorza. They also have Nebulizer drugs you can take for faster action relief and longer action. See what each of them say and decide. I know it's a shame that insurance gets to dictate what drug you can take when your doctor knows best!! I told my insurance rep. not to worry bout it I'll just go to the E.R. when I feel bad instead of paying 75.00 a month for a med that works!!! (it didn't even bother him when I said it) WHAT A SHAME!!!!
