Approx 4 years out of date?!
I stopped suffering with asthma around 4 years ago but it’s started up again. I started wheezing last night and I’ve just been for a run and I’m wheezing like mad. I still have my old inhaler and obviously can’t get another one until tomorrow.
Can I use it as an emergency even though it may not be as effective as it once was? (In other words, will it harm me??)
