I have been on Combivent and Advair inhalers for about 20 yrs. Now that I m 77 and have gained weight (from less exercise and overeating) my peak flow meter reinforces my hunches about my capacity dropping 50 points. My pulmonologist insists I haven t grown immune to my asthma meds while the Walk-In clinic believed its possibility and reason for trying Symbicort and Proair HFA on me...(to no avail). I ve increased my short term Combivent puffs to 3 instead of 2 twice daily as prescribed, although I still need to take my evening puffs earlier. Have also had a wet cough over 2 months despite Cetirizine, Metoprolor .5 mg + Montelukast 10 mg RX. Any thoughts?
Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, your lung disease have worsened because your peak flow reading has been Chat Doctor.  So better to consult pulmonologist and get done PFT (Pulmonary Function Test).PFT will tell you about severity of the disease and treatment is based on severity only. You may need newer ultra long acting inhaled bronchodilators (indacaterol and glycopyronium). Deep breathing exercises and incentive spirometry are also beneficial for lung functions. Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
