Yikes, that's not good! I hope you get it very soon, and get your lungs back to happy.
Believe it or not, I ALSO mixed up my Flovent this month.
I called in the refill, then I was surprised to learn there were no more refills left, then a comedy of errors ensued, then I finally got it like 5 days later. And of course, the day after I have my first significant symptoms in like 2 months is the day that I don't get my refill on time!
I finally figured out that the reason I mix up the inhaler refills is because there's no prescription label ON the inhaler itself, so I forget when I'm out. So, when I finally did get it, I got a Sharpie and wrote on the actual inhaler
how many refills I had left! (And the Rx number, though that's not relevant if you are mail-ordering.)
