I believe that was budesonide using a nebulizer, not the OTC nasal spray. Also was for one of the earlier variants, not Omicron.

I’m not a physician, and I haven’t stayed at a Holiday Inn Express in several years, so take this for what it’s worth.
Me neither...But sometimes I play one on Free Republic.
