I have been using Fostair for some time now but have found that it looses its effectiveness as the inhaler is used.
This really caught me out this time ,after a infection, when I was not getting any benefit from the inhaler at all. Changing to a new one radically improved my breathing.
Checking the old one it still had 30 puffs left in it.
I know that the inhaler should be stored in a fridge but I'm wondering if it should still be kept cold whilst I'm using it.
