Just diagnosed with asthma

Hi, 11 days ago my Doctor said it seems I've developed adult onset asthma, after being poorly for 4 months with various colds/coughs. He's given me a preventer inhaler to take am & pm (Clenil Modulite), and a blue inhaler to take whenever I need it. How long does it normally take for the brown inhaler to start working? As I'm taking the blue inhaler about 7 times a day at the moment, and definitely don't think the Clenil Modulite has made any difference so far, infact the last 3 nights have been worse. Look forward to hearing from someone

I don't have any experience with clenil modulite specifically but they do say allow 2-3 weeks to get the full effect of a preventer inhaler

hope you start to feel better soon xx
