Been on brown 100 aerosol inhaler for years did nothing. Just made me cough more. I told them n told them. Hosp trip other day. Docs there said may need changing Ermm ya think. Now on fostair 100/6 pink inhaler. Anyone know the difference? Still coughing. Can't sleep. Pink needs time to wrk admitting. Left me 3 mths to cough last time. Anyone else having these probs?
