Does Seretide (Advair) work if it does not come in a foil pouch?
I just found out that Seretide is the same thing as Advair, and it is so much cheaper to buy Seretide in Mexico. However, it does not come in a foil pouch like Advair. The Advair instructions emphasize that it is only good for 30 days after opening the foil pouch. So I am wondering if anyone has tried the Seretide from Mexico, without the foil pouch, and if it still works. Thanks for your help.
