I have been using this for a couple of years now and the question came up among others that use it too 'how do you tell when the inhaler is empty of medication?" Yes, I know there is 200 doses but it is very impractical to keep a log of every time you use it because we carry it where ever we go for that "emergence dose." So how do you tell??
I've searched the internet for this information and either I'm using the wrong keywords or there isn't any information like this.
