Hi! I have currently have a small(ish) blue aerospace chamber spacer that I was prescribed when I had my first inhaler in the summer, I know they say to replace every 12 months, however the seal bit where the inhaler goes in has come very loose, and it keeps coming off every time I take my inhaler out, so I don’t think it will last the 12 months... so I’m going to need a new one, and I was curious as to how any of you get them replaced? Do you buy your own from a pharmacy/online (are they even readily available to buy??), or are they always prescribed? If prescribed do you think they would give me another one before it’s due?
