As a halakhic matter, do you have any thoughts on using an aerosol asthma inhaler on Yom Kippur? Not life threatening requirement. Also, for what it’s worth, taste is disgusting.
It should be totally fine. It’s just medication. And it tastes bad. Not אכילה or שתיה.
Just for clarity – “It’s just medication” does not mean one can chew good tasting vitamins or the like. This is just directly putting the medicine into the lungs and can in no way be considered an act of eating or drinking.
