Ive had asthma now for 5 months. I have both inhalers-blue and brown. After taking the brown inhaler as prescribed-day and night, im still finding that im getting my usual symptoms-tight chest, coughing and getting out of breath after walking up the stairs. Im using my blue inhaler frequently as well as the brown inhaler as prescribed. My boyfriend has noticed my symptoms affecting me a lot more too. Could it be that i need stronger inhalers?
