I am on a trial of brown inhaler, two puffs each morning and night and blue inhaler 'when needed'. Can someone let me know:
1. How long do the inhalers last? I don't want it to run out unexpectedly but not got another hospital appointment until May.
2. When is 'when needed'? My GP set me off using it every 4 hours. Others I spoke to say it's when they get a tight chest or breathless. I don't get that, I just have a bad chesty cough which has gone on for months so I am not sure when to take it.
