@marmee26 When you buy nebulizer cups, make sure you are getting "reuseable" ones, and not the disposables, which are cheaper and meant to be used once (or for a day or 2 by a single user) and thrown away. One time (I learned my lesson) I purchased some pre-packaged no-name ones online but not from a medical supply. They were labeled as reuseable, but clearly were not - the first time I boiled them, they warped. I put them in the closet to use for my grandsons when they sleep over & remember the meds but forget the cup.
