There are times when I have a little bit of trouble breathing; mostly it is when I am around people who are wearing cologne or perfume and it irritates my throat. I was hospitalized with pneumonia and was given two different inhalers to treat my breathing issues from the infection. The Advair Diskus is convenient to carry and has a numeric read out window so you can see how many doses are left in the inhaler. I have been using this for a couple of days when I notice my breathing is a little labored and it starts to work in less than ten minutes but in most cases I can feel it opening up my lungs in a matter of minutes. This is used the same way as a regular inhaler but the delivery system and set up design are more modern. If you are used to a regular inhaler it might take a little bit of time to get used to this one but the results are about the same. I don't have any ongoing or recurring issues with breathing but it is nice to know that if I need this, it is there. I started with 60 doses and expect to have that last at least three months if not more. I am sure that if I need a refill I will be able to get one from my doctor but I don't have to become dependent on having something like this to improve my breathing. It is covered under my current insurance plan so I am lucky that I was able to get it without paying a co-pay or for the whole thing out of pocket.
