Beclomethasone
"I would give a higher rating except that , as others have noted, I don't get the stated 120 doses per canister.  Qvar works very well for me when I get the recommended dosage.  When the canister starts to fail and I don't realize I'm not getting the prescribed amount things go downhill.  I don't like paying for medicine I don't get but the far bigger issue is not getting the protection Qvar provided when I do get it.

If the manufacturer fixed this I'll be very happy with Qvar."
