I am not questioning the use if you have Covid. I am questioning the protocol since inhaler doesn’t seem to be what common people get - unless it has recently changed.
I understood your question.
I have had to use an inhaler 3 times in the last 20 years to open my lungs for the flu.
Recently had covid,
Prescribed Paxlovid
Quarantine for 5 days
No inhaler mentioned or offered
