I once tried an inhaler I rediscovered in my kitchen drawer. It was perhaps 5 yr old.
I had not had a need for it for a long time, and was just testing to see if it worked.
About other drugs, I read or was told that medicine in tablets or dry form lasts much longer than in liquid form. Perhaps that also explains the inhaler going bad.
