Can anyone please advise. My daughter has been well for the last 5 months. no coughing which is the longest time ever. we now have an asthma plan in place which is 2 puffs of the preventer (dark brown) twice a day. her peak flow is normal around 200 - 240 if this drops to 160 we are to give her 2 puffs of the blue inhaler 4 time a day. the weather has been unsettled and she now has a cold which has started the coughing again. her PF dropped a little but today back good. But she is coughing all night and all day today. its been 2 days taking the blue inhaler but no change. Can I increase the Brown inhaler I wonder. she is well in herself but this cough is starting to get worse. a visit to the docs if no change but wonder if anyone has some helpful advise.
