Would Midodrine cause my 84 year old hospice patient to have a constant, dry hacking cough. His BP is 144/104, heart rate 106. O2 sat 99% on room air. No idea why this was prescribed as he does not have a history of low BP or orthostatic HTN. He is absolutely miserable at present. Will not lay down. Increased work of breathing for sure but lungs are clear. Not relief with 10mg MS Elixir. I m hoping to understand what changed if anything. He has fine petechiae over his face and nose.
