Picture of How does an Advair dispenser work?
Did you ever wonder how an Advair Discus dispenser works? I did. Here's what I found.

Step 1: Remove the outer cover

 Peel the labels off to expose the center axle.
This whole thing just snaps together and will just as easily unsnap to come apart.
Pry the outer case away from the inner carrier and it will pop off.
Once free, the inner carrier easily slides out.

Step 2: Open the inner carrier

 This is the meat of the device. It's all snap together pieces though so it comes apart easily.
First, pop off the mouthpiece.
Then work your way around the edge to free the 3 snaps. Finally, there are 2 more snaps under the mouthpiece and the top will pop right off.

Step 3: Examining the inside.

 Now that the unit is open, We find that the medicine was contained within dimples along a strip of foil in much the same way as caps from an old cap gun held a small powder charge. One side of the device peels a foil cover from the dimples to expose each next dose of medicine. This happens every time you depress the cocking lever.
These rolls slide easily off their capstans.

Weird I just opened my old one a few days ago, for the same purpose. To find out how it works.

Every time I see one of these I think of that pistol that hides in the palm.

This is incredibly timely!  I was just wondering exactly how it worked this morning!!!  Thanks for the great article.

 I did this because some friends were wondering if there was any way to overdose. Due to the nature of the advancing medicine pods, I would say, NO there is no way to OD on advair.

Very interesting, and good documentation of the disassembly!

So theoretically, this could be made much "greener" by providing the user with a single dispenser case, and just refilling it with new spools of medication. 

Of course, that's how birth-control packaging is supposed to work, too, but they send my wife a whole complete plastic case with blister pack for each one :-(
