I am 75 years old. Within the last year I was diagnosed with interstitial lung disease and have dypsnia. I am using a basic albuhterol inhaler which in my opinion does not help me much. I have tried drugs for stress. None seem to work well for me. I am on a new blood pressure med--Losartan. I have difficulty breathing when I lay down at night. I m allergic to sulfur-containing drugs which I found out while taking lisinopril I get anxiety feelings--not fun. I have problems catching my breath too. I need a plan that will head me in a new direction. I also take Hytrin at bedtime and trazadone. Can losartan be part of any problem I have?
