Hello everyone, hope we are all coping well. Just want to ask maybe a very silly question, but, at what number reading do you discard a metered dose inhaler (like Fostair)? It strts at 120. Last month i finished it up to 0 but felt like there is nothing there but air. Now with my current one, i am on reading 10 but i felt like from 20, i feel it is not giving me relief. Sorry if i did not explain it properly. When do you start a new one?
Thanks for taking the time to reply.
All the best us here!
