if for any reason dr says no, GO GET A NEW DR
if u have insurance then great, if not u may need to
buy online because some of these inhalers can cost $230 for a single canister and u can buy the same online for about 28, I can't put a website as it is considered advertising but u can google FORACORT and find online pharmacies, azmacort is a pure corticosteroid which u would use daily and then only use the provental as needed
good luck
