Why would flovent doses disappear very quickly?

Question unclear: Do you mean the container is emptying too quickly? Over the years I have had a few younger patients who, when adult supervision was absent, would activate their inhaler into thin air over and over. Kinda fun. I prefer inhalers like Flovent that have counters on the device so that one knows how many doses are left. Considering the exorbitant price of these drugs every inhaler should have a counter!
