This is crazy, dangerous even, what if you lost it when you were out?! You’d have to wait until you could get a replacement. It’s supposed to relieve your symptoms immediately they start, you shouldn’t have this worry. I have them everywhere, next to bed, in car, handbag etc. My GP wouldn’t dream of rationing them, they last longer this way anyway. I also get the proper Ventolin brand, don’t know why but it’s never been changed to generic & I agree with Happylondon, Ventolin is best. I use the nebules too, when I have an infection.
If you can’t get an appointment, write a personal letter to your GP & explain the situation. Also, when you’re not needing it so often, stock up as peege suggests.
