asthma, acute
"Just started using this one particularly, but every brand of MDI has similar issues people are complaining of here. I saw lots of reviews about it clogging and being useless. Just thought I'd recommend what I've learned to others to fix this problem. If you put warm/hot water in a cup and let it soak for a few seconds.. (I'll even shake it around in the water to help clean it) then dry it on a window sill or somewhere warm. You'll find that it will unclog the dispenser and is good as new  (as long as it is dry before you use it again). Happy breathing. Xoxo."
