I just recently purchased a 3 month supply of Seretide, which is said to be Advair with a different name in Canada and other countries besides the U.S.
I bought this because I don't have insurance that covers the cost of prescriptions and seretide is about 100 dollars cheaper than Advair. Well I just started using the seretide and it doesn't seem to be working the same as Advair. Does anyone know any information on Seretide or know if it's different?

Also it's the same dosage so that's not the problem.

Any help on this would be very greatful.
