Can we do inhaler/nasalspray emptyStoma.

I have cold (running nose) problem since childhood. I was diagnosed with asthma in 2016 and have been taking budamate inhaler twice a day, arzep nasal spray twice a day, metatop nasal spray twice a day. Earlier i used to do nasal spray - Arzep and Metatop daily twice a day. But now i do whenever i have cold (running nose) My asthma is controlled and cold is controlled with nasal spray. My questions 1. After wakeup in morning, i get running nose some days, can i do nasal spray (arzep and metatop)empty stomach. And can i do inhaler empty stomach? 2. Is there any side effect if these nasal sprays- arzep and metatop are used daily over long period. My cold gets controlled with arzep . Is there any ill effect of these nasal spray?
